2055 Q. No. 10^-2 mole of KOH is dissolved in 10 litres of
water. What will be the pH of the solution?
12
Ans: pH = 11

11

Explanation:

Moles of KOH =

Volume of water = 10 liters

Concentration of KOH is given by

is strong base so we have the following relation

So, pH of the solution is 11

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
