Calculate the pH of each of the following solutions.
Dominique Jan T.
Calculate the pH of a buffer solution that is 0.856 M HC2H3O2 and 0.326 M KC2H3O2. The Ka for HC2H3O2 is 1.8 !! 10-5. Hint: you can use the Henderson-Hasselbalch equation. Type your numerical answer using three significant figures. HC2H3O2 (s) + H2O (l) → H3O+ (aq) + C2H3O2- (aq) Determine the pH of a 0.216 M HNO3 solution. Consider HNO3 to be a strong acid. Round your answer to two significant figures. What is the solubility, in g/L, of PbF2 in water? The Ksp for PbF2 is 2.7 x 10-8? PbF2 (s) → Pb2+ (aq) + 2F- (aq)
Supreeta N.
Calculate the pH of a buffer solution that is 0.20 M in sodium formate (HCOONa) and 0.15 M in formic acid (HCOOH). Ka = 1.8 x 10-4 for formic acid You must show how you derived your answers to receive credit. No file uploads. Thanks!
