Question

For dissociation constant $\left(K\right)$ and ionic product $\left(K_w\right)$ of water which is correct?

• A. $K>K_w$
• B. $K_w>K$
• C. $K_w=K$
• D. None of these

Answer 1

The correct option is B $K_w>K$

The value of ionisation constant of water is $1.8\times {10}^{-16}\text{and}\frac{1}{55.55}$ times that of $K_w$, the ionic product of water.

So $K_w>K$.

Hence option B is correct.
