Question

A substance is dissolved in water, where it breaks apart and releases H+ ions. 30% of the substance breaks apart. This substance is a...A.) strong acidB.) weak acidC.) weak baseD.) strong base

Answer 1

B.) weak acid

Explanation.

Acids are substances that dissociate or dissolve in water to release H⁺ ions. However, strong acids dissociate completely (100%) in water to release their H⁺ ions while weak acids are ones that do not dissociate completely in solution; this means that a weak acid does not donate all of its hydrogen ions (H+) in a solution.

Hence, the correct option is: B.) weak acid
