What is the pH of a solution of H2SO4 that has [H3O ] = 5. 45 × 10–5 M? Round to the nearest hundredth.

Sagot :

pH is the estimation of the basicity and acidity of the substance or the aqueous solution. The pH of the sulfuric acid is 4.3.

What is the formula for pH?

pH is a numbered scale used for the estimation of the acidic and alkaline solution. It is measured concerning the concentration of the hydronium ions.

pH is calculated by the formula:

[tex]\rm pH = -log [H_{3}O^{+}][/tex]

Given,

Concentration of [tex]\rm H_{3}O^{+}[/tex] =  [tex]\rm 5. 45 \times 10^{-5} \;\rm M[/tex]

Substitute the value in the above equation:

[tex]\begin{aligned}\rm pH &= \rm -log[5.45 \times 10^{-5}\;\rm M]\\\\\rm pH &= 4.3\end{aligned}[/tex]

Therefore, 4.3 is the pH of the sulfuric acid solution.
