Solution

$p H = - l o g [H^{+}]$
Where $[H^{+}] =$ Hydrogen\quad ion\quad concentration
In this case, $[H^{+}] = 1 \times 1 0^{- 4}) = 1 0^{- 4}$
$- l o g 10^{- 4} = - 4 (- l o g 1 0^{- 4}) = - (- 4) = 4$
$p H = - l o g 1 0^{- 4}$ = $4$
Hence the solution is acidic.

The concentration of hydrogen ion a solution is 1×10−4 mole L−1. Find the pH of this solution. Is it an acidic or a basic solution?

pH=−log[H+]Where [H+]= Hydrogen\quad ion\quad concentrationIn this case,[H+]=1×10−4)=10−4 −log10−4=−4(−log10−4)=−(−4)=4pH=−log10−4=4Hence the solution is acidic.
