Answer:
Lower the pH by several units.
Exceed the buffer capacity.
Step-by-step explanation:
The options are:
*Raise the pH slightly
*Lower the pH slightly
*Raise the pH by several units
*Lower the pH by several units
*Not change the pH
*Exceed the buffer capacity
The hydrochloric acid reacts with potassium hypochlorite to produce hypochlorous acid. The amount of HCl added is the HClO produced and the KClO consumed. As the moles of HCl > moles KClO, all the KClO is consumed exceeding the buffer capacity and lowering the pH by several units.
