Question:

How many milliliters of 0.100 M HCl are needed to completely neutralize 52.0mL of 0.110 M Ba(OH)₂ solution?

Solution:

$$Ba(OH)₂ + 2HCl = BaCl_2 + 2H_2O$$ $$\begin{array}{l} n(Ba(OH)₂) \, (\text{mmole}) = 52.0 \times 0.110 = 5.72; \\ n(HCl) \, (\text{mmole}) = 2 \times 5.72 = 11.44; \\ V(HCl) \, (\text{ml}) = 11.44 / 0.100 = 114.4; \\ \end{array}$$

Answer: 114.4
