Question

If the concentration of H${}^{+}$(aq) ions increases in a solution, the acidity:

• A. increases
• B. decreases
• C. remains same
• D. None of the above

Answer 1

The correct option is A increases

Hydrogen ion concentration in a solution gives the acidity strength on a pH scale. If an acid is added to the solution, hydronium ion concentration increases which increases the acidity if the solution. If any base is added it has more hydroxide ions which increases the basicity of the solution and makes it more alkaline in nature.
