Answer:
Explanations:
The formula for calculating the pH of the solution is given as:
[tex]pH=-log[H_3O^+][/tex]Given that the pH is 2, then;
[tex]\begin{gathered} 2=-log[H_3O^+] \\ log[H_3O^+]=-2 \\ [H_3O^+]=10^{-2} \\ [H_3O^+]=0.01M \end{gathered}[/tex]Hence the concentration of the hydronium ion is 0.01M
Since the pH of the solution is less than 7, hence the solution is acidic
