What is the pH of a solution with a concentration of 4.2 × 10–5 M H3O+? 2.31 4.38 5.62 6.87
Eva8 [605]
<h3><u>Answer</u>;</h3>

pH = 4.38

<h3><u>Explanation;</u></h3>

Consider that ;

[H3O+] = 10-pH mol/L  

 Therefore; the pH is the -log of the [hydronium ion].  

pH = - log [H3O+]

Thus;

pH = - log (4.2 × 10^–5)

     = 4.38
