What does inert mean in science?

Definition – An inert chemical substance is one that is not generally reactive. This is a synonym for “inactive” with respect to chemical reactions. Inert has a non-chemical meaning of being unable to move or resist movement; for example, “the accident victim was laying on the ground, inert.”

What is the meaning of inert items?

Something that’s unable to move or moving without much energy can be described as inert. Wind up in a body cast and you’ll find yourself not only itchy, but totally inert. When motion is restricted or sluggish, or when something or someone appears lifeless, the adjective to use is inert.

Does inert mean neutral?

Neutral gases are often called inert gases. That means that these gases do not initiate chemical reactions by themselves. Nitrogen is an inert gas. It does not react under normal conditions.

What is the synonym of inert?

Some common synonyms of inert are idle, inactive, passive, and supine. While all these words mean ‘not engaged in work or activity,’ inert as applied to things implies powerlessness to move or to affect other things; as applied to persons it suggests an inherent or habitual indisposition to activity.

How do you know if something is inert?

In chemistry, the term chemically inert is used to describe a substance that is not chemically reactive. From a thermodynamic perspective, a substance is inert, or nonlabile, if it is thermodynamically unstable (positive standard Gibbs free energy of formation) yet decomposes at a slow, or negligible rate.

What materials are inert?

Inert materials are classed as ‘waste that does not undergo any significant physical, chemical or biological transformations and is unlikely to adversely affect other matter with which it comes into contact’. To you and I, this waste includes brick, concrete, hardcore and subsoils which cannot be reused/recycled.

Does inert mean non toxic?

Inert Ingredients – Pesticide products contain at least one active ingredient and other intentionally added inert ingredients. Called “inert ingredients” by the federal law, they are combined with active ingredients to make a pesticide product. Inerts are chemicals, compounds, and other substances, including common food commodities (e.g., certain edible oils, spices, herbs) and some natural materials (e.g., beeswax, cellulose).

  • The name “inert” does not mean non-toxic.
  • All inert ingredients must be approved by EPA before they can be included in a pesticide.
  • We review safety information about each inert ingredient before approval.
  • If the pesticide will be applied to food or animal feed, a food tolerance is required for each inert ingredient in the product, and we may limit the amount of each inert ingredient in the product.

Inert ingredients play key roles in pesticide effectiveness and product performance. Examples of functions inerts can serve include:

Act as a solvent to help the active ingredient penetrate a plant’s leaf surface. Improve the ease of application by preventing caking or foaming. Extend the product’s shelf-life. Improve safety for the applicator. Protect the pesticide from degradation due to exposure to sunlight.

Under federal law, the identity of inert ingredients is confidential business information. The law does not require manufacturers to identify inert ingredients by name or percentage on product labels. In general, only the total percentage of all inert ingredients is required to be on the pesticide product label. Information on inert ingredients:

What are 3 examples of inert items?

Examples of inert ingredients include emulsifiers, solvents, carriers, aerosol propellants, fragrances and dyes.

What are the types of inert?

There are six primary inert gases which include helium, neon, krypton, argon, xenon, and radon.

Is plastic an inert material?

1. Introduction – Plastics are considered to be biochemically inert materials that do not interact with the endocrine system because of their large molecular size, which prohibits their penetration through the cell membrane. However, plastic debris present in the marine environment (marine plastics) carry chemicals of smaller molecular size (MW Sonnenschein & Soto 1998 ), while some phthalate plasticizers have been associated with reduced testosterone production (e.g.

  • Foster 2006 ).
  • A wide range of biological effects have been reported for polychlorinated biphenyls (PCBs; Neal 1985 ).
  • Reviews of human and wildlife exposure to plastics additives are also available in this volume ( Koch & Calafat 2009 ; Meeker et al,2009 ; Oehlmann et al,2009 ).
  • The objective of this paper is to review the phenomena by which plastics released to the environment serve as carriers of organic contaminants to wildlife.

The first two sections describe leaching of contaminants from plastics in landfills. Section 2 reviews the migration and degradation of plasticizers (phthalates), additives (organotin compounds and nonylphenols (NP)) and monomers (BPA), while §3 focuses on landfill leachate as a source of plastics-derived endocrine-disrupting compounds.

The following sections address the uptake of contaminants from the environment onto plastics. In §4, sorption is described mathematically and the model validated by experimental observations. Section 5 summarizes the types and quantities of contaminants found sorbed to plastics collected from the marine environment.

The remaining sections emphasize plastics as a vector in the transport of contaminants to animals. Section 6 presents an overview of the transfer of plastic-derived contaminants to organisms. This is expanded in §7, which describes literature concerning the transport of contaminants to sediment-dwelling invertebrates.

Are any metals inert?

The Noble Metals – Gold, Silver, Platinum, Palladium and – So that leaves us with what are known as the “noble” metals, Just like there are noble gases, (noble meaning “inert”), these metals are not active. I want you to think of the noble metals as the royalty of all metals,

  • Copper,
  • Silver,
  • Gold,
  • Platinum,
  • Palladium,
  • Ruthenium, Rhodium, Osmium, and Iridium.

Historically, copper, silver, and gold have been known as the coinage metals. And scientists deem these 3 as the “real” noble metals because of their electronic structure. Copper does react with oxygen, which is where the Statue of Liberty got its bluish-green color from.

  • But the result of copper interacting with oxygen is not corrosion, like rust.
  • It’s the exact opposite.
  • The process is called “passivation,” and the bluish-green color is actually a layer of protection that protects the copper from natural debasement.
  • That is why copper is included in the noble metals.
  • It does “interact,” but it doesn’t corrode.

This interaction acts as a protective barrier for the copper, but changes its appearance—damn two-faced metal! Silver is a bit kinky, too. It reacts with sulfide gas in the atmosphere, which causes it to look tarnished.

  • Removing the tarnish is natural debasement: every time you polish the silver to get rid of the tarnish, you will be removing some silver, thus debasing it.
  • The remaining noble metals just aren’t practical for use as a store of value.
  • Not only are they hard to smelt and difficult to work with, but they are also too scarce in nature to be able to meet the need as a store of value.

And they all look kind of ugly, very little sex appeal. Think silver, but without the sexiness and brightness. A blah grey is what the platinum group of noble metals look like. Nobody wants blah ! In fact, all the metals on the periodic table of elements except copper and gold are a variation of grey. Silver is at least a sexy version of grey. The rest are just variations of a dull grey.

Does inert mean stable?

An inert chemical is one that is stable and unreactive under specified conditions. At one time, the noble gases in Group 18 of the periodic table were known as the inert gases, because they had not been observed to form any compounds. However, most of the noble gases have now been observed to form compounds, although generally under unusual conditions.
