What is a compound a pure substance?
A pure chemical compound is a chemical substance that is composed of a particular set of molecules or ions that are chemically bonded. Two or more elements combined into one substance through a chemical reaction, such as water, form a chemical compound.
Is a compound considered a pure substance Why Why not?
A chemical compound is considered to be a pure substance. This is because each molecule of the chemical compound has the same chemical formula.
What is considered to be a pure substance?
A substance that has a fixed chemical composition throughout is called a pure substance such as water, air, and nitrogen. A pure substance does not have to be of a single element or compound.
What do you mean by pure substance?
Why is pure substance important?
Purity can also have an important impact on the chemical properties of a substance. Pure substances have the potential to form predictable products from chemical reactions. Therefore, chemists often use substances of high purity when conducting chemical research.
What are the types of pure substances?
Examples of pure substances include tin, sulfur, diamond, water, pure sugar (sucrose), table salt (sodium chloride) and baking soda (sodium bicarbonate). Crystals, in general, are pure substances.

What is not a pure substance?
Examples of Substances That Are Not Pure. In general, any heterogeneous mixture is not a pure substance. If you can see differences in the composition of a material, it’s impure, at least as far as chemistry is concerned. Rocks. Oranges. Wheat. Light bulbs.
