A solution has a pH = 4.63. What is the [H3O+] concentration? [H3O+] = 10-pH Remember this expression is the inverse of pH = -log[H3O+]
Answers: 3
![pH = - log [ { H_3O}^{+}]](/tpl/images/0954/0497/1a2ed.png)
![4.63 = - log[ { H_3O}^{+}] \\ [ { H_3O}^{+}] = {10}^{ - 4.63} \\ \\ = 2.344 \times {10}^{ - 5} mol {dm}^{ - 3}](/tpl/images/0954/0497/100a3.png)
