Question

Which type of substance ionizes completely and creates hydronium ions when dissolved in water?

Answer 1

Answer: strong acids

Explanation: for one the substance dissolves completely and acids only produce hydronium ions just like acids produce hydroxide ions.

Answer 2

Strong acids.

Step-by-step explanation:

• Acid is a substance that produces hydronium ions (H₃O⁺) when dissolved in water. Acids have a pH less than 7.

• The degree of hydronium ions (H₃O⁺) depends on the strength of the acid.

• Strong acids are completely ionized and produce hydronium ions (H₃O⁺).

HA + H₂O → H₃O⁺ + A⁻.

• Weak acids are partially ionized and produce hydronium ions (H₃O⁺).

HA + H₂O ⇄ H₃O⁺ + A⁻.
