Which of the following comounds is a salt?

Question

A). HBr

B). KNO3

C). H2SO4

D). NaOH

E). C6H12O6

Answer 1

Depends. A, C, and E are certainly not salts, because they are covalent compounds (and a salt needs to be ionic.) Some people define a salt as an ionic compound whose anion is neither hydroxide (OH-) or oxide (O2-). If this is the case then only B is a salt. If however you define a salt as any ionic compound, then B and D are both salts.

Answer 2

D

Answer 3

KNO3 y NaOH
