Toxicity is quantitative because it can be measured, after a fashion.
The usual measure of toxicity is the LD50 (or some minor variation on it). This is the amount of the substance (usually specified as a fraction of body weight) required to kill half of a group of experimental animals (usually rats or mice). It's also customary to specify the method of exposure: injection, ingestion, rubbing it on them, or what.
So a given compound might have an LD50 of 1.2 mg/kg in mice (intravenous). This means that giving a 20g mouse an injection containing 24 micrograms of the material in question has a 50/50 chance of killing it. This may carry over (roughly) to other species, or it may not, and injecting 0.084 grams into a 70 kg person could be anywhere from almost completely safe to almost certainly lethal, depending on how efficient the human metabolism is compared to mouse metabolism in dealing with that particular chemical. However, at least it's a start.

Is toxicity chemical or physical property?
Chemical: Toxicity is about a harmful material interacting chemically with other substances in the body.
Is toxic a physical or chemical property?
Toxicity is a chemical property. You can not see the toxicity just by looking at it.
5 An example of a chemical property is?
flammability, reactivity with acids, or toxicity. Chemical properties describe how a substance reacts with other substances or undergoes chemical changes.
What property describes the ability of a substance to change into other substances?
chemical property.
What is a chemical properties of a substance?
Chemical property means the reaction of any substance with others.

Is toxicity a example of chemical property?
Yes.
Why penicillin exhibits the property of selective toxicity?
Penicillin exhibits the property of an effective and safe antimicrobial therapy that involves selective toxicity. This is because the chemical structure of Penicillin gives antibacterial properties.
Is poisonous is chemical property?
No, poison is not a chemical property. Poison refers to the harmful effects a substance can have on living organisms, while chemical properties describe how a substance behaves in chemical reactions, such as reactivity, flammability, and toxicity.
What does the word chemical property mean?
Chemical properties describe how a substance interacts with other substances to form new substances. These properties can include reactivity, combustibility, acidity, and toxicity. Chemical properties are inherent to the substance and help determine how it will behave in a chemical reaction.
5 An example of a chemical property is?
flammability, reactivity with acids, or toxicity. Chemical properties describe how a substance reacts with other substances or undergoes chemical changes.
Is toxicity is a qualitative property or a quantitative property?
It is a quantitative property because a substance toxic level can be measured and assigned a value Save
What are the properties of chemical property?
· General chemical properties: - Pauling electronegativity - Period - Group - Flammability - Corrosivity - Heat of combustion - Enthalpy of formation - Valence (oxidation states) - Toxicity - Chemical stability in a given environment - Coordination number
What is a chemical reaction and a chemical property?
A chemical reaction is a process that involves the breaking and forming of chemical bonds between atoms, resulting in the transformation of substances into new substances with different properties. A chemical property is a characteristic of a substance that describes its ability to undergo chemical reactions or changes, such as its reactivity, flammability, or toxicity.
What is the chemical property of matter?
* General chemical properties: - Pauling electronegativity - Period (position) - Group (position) - Flammability - Corrosivity - Heat of combustion - Enthalpy of formation - Valence (oxidation states) - Toxicity - Chemical stability in a given environment - Coordination number
Do Metabolism of a chemical always reduces its toxicity?
yes
