Strong Acids and Bases, pH, pOH Practice Test

A student prepares a $1.0\times10^{-3},\text{M}$ solution of HCl$(aq)$ in water at $25^\circ\text{C}$. Assuming HCl is a strong acid that completely dissociates, what is the pH of the solution?

A $2.0\times10^{-4},\text{M}$ solution of Ba(OH)$_2(aq)$ is prepared in water at $25^\circ\text{C}$. Ba(OH)$_2$ is a strong base that completely dissociates. What is the pOH of the solution?
