Of the three blocks in the reading, which one does not turn down the mA lower than 0.8 current when using the PNS technique?

What is the pH of a buffer solution that contains 0.40 mol nitrous acid (HNO2) and 0.30 mol potassium nitrite (KNO2) in water sufficient to yield 1.0 L of solution?  Hint: The Ka of HNO2 is 4.0 x 10-4.

What is the pH of a buffer solution that contains 0.40 mol hydrocyanic acid (HCN) and 0.30 mol potassium cyanide (KCN) in water sufficient to yield 1.0 L of solution?  Hint: The Ka of HCN is 4.9 x 10-10.
