Answer:When the pH of the solution is changed from 1 to 2 the concentration of the \(H_3O^+\) in solution gets low.
Explanation:
The pH of the solution is defined as negative logarithm of \(H_3O^+\) ions concentration in a solution.
\(pH=-\log[H_3O^+]\)
1. \(H_3O^+\) ions concentration when pH is 1
\(1=-\log[H_3O^+]\)
\([H_3O^+]=0.1 M\)
2. \(H_3O^+\) ions concentration when pH is 2
\(2=-\log[H_3O^+]\)
\([H_3O^+]=0.01 M\)
When the pH of the solution is changed from 1 to 2 the concentration of the \(H_3O^+\) in solution gets low.
