QUESTION 2 The strong acid, HCl, is titrated with a strong base, NaOH, in aqueous solution. What is the pH of the titration solution after the addition of 17.94 mL of 0.100 M NaOH to a 50.00 mL of 0.100 M HCI? Write your answer using 3 significant figures,
What is the pH of a solution of 20.00 mL of 3.00 M HCL that is titrated with 10.00 mL of a 6.00 M solution of NaOH ? (Note both acid and base are strong)
Titration of 25.00 mL of 0.100 M HCl with 0.100 M NaOH (strong acid, strong base): Answer the following questions: 4. Calculate the initial pH 5 Why is pH = 7 at the equivalence point? 6Why does the pH rise slowly at first, very rapidly near the equivalence point, and slowly after the equivalence point? 7. Why does it require 25.00 mL of NaOH to reach the equivalence point?
A chemist titrates 150.0 mL of a 0.4938 M sodium hydroxide (NaOH) solution with 0.6911 M HNO, solution at 25 °C. Calculate the pH at equivalence. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of HNO2 solution added. pH = 0
