pH and Activity
Calculate the pH of a solution which is 0.0010 M in KOH and 0.013 M
in NaNO3 using activities.
Calculate a pH for the same solution, ignoring
activities
Which of the following will produce the solution with the lowest
pH?
(A) 0.2 M HCl(B) 0.5 M HF(C) 0.2 M KOH(D)
0.5 M HClO4(E) There is not enough information to
predicT
please help? im kind of lost
8. You have prepared a 0.2 M acetate solution with a pH = 4.76.
Determine the resulting pH when the acids and bases below are added
to the solution. The pKa of CH3COOH is 4.76.
a. 0.025 M HCl
b. 0.050 M HCl
c. 0.025 M NaOH
d. 0.050 M NaOH
e. 0.050 M HCl and 0.025 M NaOH
f. 0.025 M HCl and 0.050 M NaOH
Calculate the ph of a solution that is 0.30 M in ammonia (NH3) and
0.20 M in ammonium chloride. Kb=1.76 x 10^-5
Then calculate the ph if you add 10 mL of 1.0 M HCl to 50 mL
of your solution in the problem above.
