In the titration of 20.00 mL of 0.175 M NaOH, calculate
Chapter 17, Problem 47(choose chapter or problem)
In the titration of 20.00 mL of 0.175 M NaOH, calculate the number of milliliters of 0.200 M HCl that must NH3(aq) NH3 NH3(aq); NaHCO3(aq) NH3(aq) + HCl(aq) NH4 +(aq) + Cl-(aq) Kb = 1.8 * 10NH -5. 3 , NH3 HNO2 + OH- H2O + NO2 - Ka = 7.2 * 10HNO -4. 2 , HNO2 be added to reach a pH of (a) 12.55, (b) 10.80, (c) 4.25. [Hint: Solve an algebraic equation in which the number of milliliters is x. Which reactant is in excess at each pH?]
