The equation for the ph of a substance is ph = –log[h+], where h+ is the concentration of hydrogen ions. a basic solution has a ph of 11.2. an acidic solution has a ph of 2.4. what is the approximate difference in the concentration of hydrogen ions between the two solutions?

![[H^+]'[H^+]](/tpl/images/0295/9514/81a76.png)
![[H^+]'-[H^+]=0.39810 mol/L-6.3095\times 10^{-12} mol/L=0.0039809 mol/L=3.9809\times 10^{-3} mol/L](/tpl/images/0295/9514/79396.png)
