Question

Is there any base to neutralize citric acid ? If there any base then what is it

Answer 1

Strong base like NaOH

Bases are substances with a high pH. Like acids, bases are corrosive. However, when acids and bases contact each other, they neutralize each other and the resulting mixture is less corrosive. You can use a strong base like NaOH (sodium hydroxide) to neutralize citric acid. If you do not have access to NaOH, something like sodium bicarbonate (baking soda) will also neutralize citric acid well
