A 1.0 L buffer mixture contains 0.15 moles of HClO and 0.20 moles of NaClO. Which of the following additions would destroy the buffer (exceeds the buffer capacity)?
A. Adding 0.20 moles of NaOH
B. Adding 0.15 moles of HCl
C. Adding 0.20 moles of NaClO
D. None of the above
Homework Answers
Adding Hcl, no proble, adding NaClO, no problem, but adding NAOH will:
NaOH + HClO = H2O
0.2 mol of OH- + 0.15 mol H+ = 0.05 mol of OH- in excess, therefore no acid left for buffer
the buffer is destroyed!
