Question 1
For PbCl
2 (K
sp = 2.4 × 10
–4), will a precipitate of PbCl
2 form when 0.10 L of 3.0 × 10
–2 M Pb(NO
3)
2 is added to 400 mL of 9.0 × 10
–2 M NaCl?
◦ Yes, because Q > K
sp. .◦ No, because Q < K
sp.◦ No, because Q = K
sp◦ Yes, because Q < K
sp.Question 2
For which type of titration will the pH be basic at the equivalence point?
◦ Strong acid vs. strong base.
◦ Strong acid vs. weak base.
◦ Weak acid vs. strong base.
◦ All of the above.
◦ None of the above.
