A 1.00 x 10^-10 M solution of chloric acid Please help me solve this to find pH and pOH​
Svetradugi [14.3K]

Answer: The pH of solution is 10.

The pOH of the solution is 4.

Explanation:

pH is the negative logarithm of concentration of hydrogen ion.

As given concentration of acidic solution is 1.00 \times 10^{-10} M. Therefore, pH of the solution is calculated as follows.

pH = -log [H^{+}]\\= -log (1.00 \times 10^{-10})\\= 10

The relation between pH and pOH is as follows.

pH + pOH = 14

pOH = 14 - pH

= 14 - 10

= 4

Thus, we an conclude that pH of solution is 10 and pOH of the solution is 4.
