Manipur Board Solutions for Chapter: Acids, Bases and Salt, Exercise 4: Exercise 4

Is the dilution of acid with water an exothermic or endothermic?

'$\mathrm{NaOH}$ dissolves in water with the absorption of heat.' Is it correct or not? If not, give the correct statement.

Why does an aqueous solution of acid conduct electricity?

What is the effect of dilution on the concentration of ${\mathrm{H}}_3{\mathrm{O}}^{+}$ ion of an acid?

What will happen to the concentration of ${\mathrm{H}}_3{\mathrm{O}}^{+}$ ion in a given volume of acid if it is mixed with the same amount of $\mathrm{NaOH}$ solution?
