View the step-by-step solution to:

How many moles of NaOH or HCI should be added to 1.00 L of 0.0272 mol L'1 HN02(aq) to produce a solution with a pH of 2.96 ?

This is from acid and base.

How many moles of NaOH or HCI should be added to 1.00 L of 0.0272 mol L‘1 HN02(aq) to produce a solution with a
pH of 2.96 ? Assume the temperature is 25 °C and no change in volume. For HNOz, pKEl = 3.14 at 25 “C. Your answer for the moles of NaOH or HCI should be accurate to 3 significant figures. To get the desired pH, Number moles of (CliCk For LiSt) 3 should be added.

What is the pH at the equivalence point when 25.0 mL of 0.175 mol L”1 HN3(aq) is titrated with 0.129 mol L”1
NaOH(aq)? Assume the temperature is 25 “C. For HNS, pKa = 4.72 at 25 "0. Give your answer accurate to two decimal places. PH = Number
