Question

When an ACID ionizes in water, the number of hydronium ions in the solution _____ and the value of the pH _?

decreases; increases


decreases; decreases


remains the same; cannot be predicted


increases; decreases


increases; increases

Answer 1

Answer: Increases ; decreases

Explanation: The more ionized the solution is the acidic it becomes, and the more acidic a solution is; the lower the pH value.

Therefore, when an acid ionizes in water, the number of hydronium ions in the solution increases and the value of the pH decreases.

Hope this helps :)
