What is the percentage protonation of the solute and Calculate the pH of the solute in an aqueous solution of 0.611 M Aqueous solution of Ammonia ( if the Kb is 1.8 × 10-5.)
Using a solution with [Ca2+] = 0.0050 M, a boy added enough solid ammonium oxalate, (NH4)2C2O4(s) to prepare initial [C2O42-] = 0.0051 M then calculate what is the percent of Ca2+ remaining in solution after precipitation?
