Chapter 14, Problem 56E

Determine $\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$ in each acid solution. If the acid is weak, indicate the value that $\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$ is less than.

a. $0.125\text{M}{\text{HClO}}_2$

b. $1.25\text{M}{\text{H}}_3{\text{PO}}_4$

c. $2.77\text{M}\text{HCl}$

d. $0.95\text{M}{\text{H}}_2{\text{SO}}_3$
