Answer: The pH of the substance is 8.25. The solution is basic.

Step-by-step explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydronium ion concentration. The acids have pH ranging from 1 to 6.9 , salts have pH of 7 and bases have pH ranging from 7.1 to 14.

$pH=-\log [H_3O^+]$

Putting in the values:

$pH=-\log[5.6* 10^(-9)]$

pH=8.25

Thus as pH is more than 7, the solution is basic.

The pH of the substance is 8.25. The solution is basic.
