# A student mixes \(50.0\text{ mL}\) of \(0.020\text{ M }\text{HCl(aq)}\) with \(50.0\text{ mL}\) of \(0.020\text{ M }\text{Ba(OH)}_2\text{(aq)}\) at \(25\ ^\circ\text{C}\). Assuming volumes are additive, what is the \(\text{pH}\) of the resulting solution?

A student mixes \(50.0\text{ mL}\) of \(0.020\text{ M }\text{HCl(aq)}\) with \(50.0\text{ mL}\) of \(0.020\text{ M }\text{Ba(OH)}_2\text{(aq)}\) at \(25\ ^\circ\text{C}\). Assuming volumes are additive, what is the \(\text{pH}\) of the resulting solution?
