Question

What type of substance has a pH of less than 7, ionizes completely in solution, and has a high molarity?

A) Strong acid
B) Weak base
C) Neutral solution
D) Non-electrolyte

Answer 1

A substance that has a pH of less than 7, ionizes completely in solution, and has a high molarity is a strong acid.

Step-by-step explanation:

A substance that has a pH of less than 7, ionizes completely in solution, and has a high molarity is a strong acid. Strong acids are 100% ionized in aqueous solution, meaning that they completely dissociate into ions. They have a low pH value and are highly corrosive. Examples of strong acids include hydrochloric acid (HCl) and sulfuric acid (H2SO4).
