Question

The hydrogen ion concentration of a solution is 0.0001mol/L. Calculate the pH (given pH = -log[H]+

Answer 1

Given:

The hydrogen ion concentration of a solution is 0.0001 mol/L

we will find the value of pH

The relation between pH and the hydrogen ion concentration H will be:

$pH=-\log H^+$

Given H = 0.0001 mol/L

so, the value of pH will be as follows:

$pH=-\log (0.0001)=-\log 10^{-4}=-(-4\log 10)=4$

so, the answer will be pH = 4
