**Titration of Hydrocyanic Acid with Barium Hydroxide**

A 39.3 mL sample of a 0.313 M aqueous hydrocyanic acid solution is titrated with a 0.202 M aqueous barium hydroxide solution. What is the pH after 13.0 mL of base have been added?

**pH =** [Input box for answer]

This problem involves the titration of a weak acid (hydrocyanic acid) with a strong base (barium hydroxide). The objective is to determine the pH of the resulting solution after the addition of a specific volume of the base. Calculating the pH involves understanding the neutralization reaction, the resulting concentrations of the reactants and products, and the application of the principles of equilibrium.
