$\huge\bf{\green{\mid{\overline{\underline{Solution:}}}\mid}}$

pH = -log[H+]

pH = -log[0.0001]

pH = -log(1.0 × 10^-4)

pH = -log 1 + 4 log 10

pH = 4 log 10 - log 1

pH = 4

$pH =-log [H^+]$

$<font color = "blue">Solve →</font color = "pink">$

=> pH = -log [0.0001]

=>pH\:=-log\:[1 × 10^-4]

=> pH = -log 1 + 4 log 10

=> pH = 4
