Explanation:
Acid is a proton donor and electron-pair acceptor. Whereas, a base is a hydroxide ion donor and electron-pair donor.
The addition of an acid or a base can affect the pH of a solution. Acids lower the pH of a solution, whereas bases increase the pH of a solution.
The pH of an acidic solution < 7 and pH of a basic solution > 7.
When equal amounts of acid and base is mixed together, the solution gets neutralized. This is known as Neutralization reaction. The pH of such a solution is neutral (pH= 7).
