A100 milliliter sample of 0.100-molar nh4cl solution was added to 80 milliliters of a 0.200-molar solution of nh3. the value of kb for ammonia is 1.79 x 10^-5.
(a) what is the value of pkb for ammonia? (b) what is the ph of the solution described in the question?
(c) if 0.200 grams of naoh were added to the solution, what would be the new ph of the solution? (assume that the volume of the solution does not change.)
(d) if equal molar quantities of nh3 and nh4+ were mixed in solution, what would be the ph of the solution?
