Okay. Sodium is a pure substance because it contains only the element sodium (Na). Sugar is not because it is a crystalline substance that contains carbon and a number of other ingredients as well.
Pure, distilled water is a pure substance, milk is not.
And the word is definition. Check your spelling please.

How long is a foot? PS= 12 inches.
How many teeth do you have?PS= 28 if you have had your wisdoms pulled. 32 if not. Etc. The pure truth. No embellishments.
The PS of novel? The plot at it's most simple explanation.
And what the one above said in a chemical situation.

Sodium is a pure substance because it is only made of one thing. Also sugar is a pure substance.
