Explain the effect of addition of an acid on ionic product of water.

The conjugate base of water is 

The conjugate acid of water is 

"Water can act as Bronsted acid as well as Bronsted base". Justify this statement.

The ionic product of water _____ if a few drops of acid or base are added to it.(remains constant/decreases/increases)

The ionic product of water _____ if a few drops of acid or base are added to it.(remains same/decreases/increases)

The ionic product of water _____ if a few drops of acid or base are added to it.

Ionic product of water changes by the addition of acid or base.

According to Bronsted-Lowry concept, a substance which can act both as acid and base is called _____

The pH of pure water at $25°\mathrm{C}$ and $35°\mathrm{C}$are $7$ and $6$ respectively. What is the heat of formation of water from ${\mathrm{H}}^{+}$ and ${\mathrm{OH}}^{-}$? 

If ${\mathrm{K}}_{\mathrm{a}}={10}^{–5}$ for a weak acid, then ${\mathrm{p}\mathrm{K}}_{\mathrm{b}}$ for its conjugate base would be -

Equal volumes of three strong acid solutions of $\mathrm{p}\mathrm{H}\mathrm{ }3,\mathrm{ }4$ and $5$ are mixed in a vessel. What will be the ${\mathrm{H}}^{+}$ ion concentration in the mixture?

At a certain temperature, the value of$\mathrm{ }{\mathrm{p}\mathrm{K}}_{\mathrm{w}}$ is $13.4$ and the measured $\mathrm{p}\mathrm{H}$ of a solution is $7$. The solution is:

At a certain temperature, pure water has hydronium ion concentration equal to ${10}^{–6.5\mathrm{ }}\mathrm{ }\mathrm{m}\mathrm{o}\mathrm{l}\mathrm{e}$ ${\mathrm{L}}^{–1}$. The value of ${\mathrm{K}}_{\mathrm{w}}$ at this temperature will be -
