What is the pH of a 0.650 M solution of methylamine (CH3NH2)? Kb=4.4x10-4
The weak base methylamine, CH3NH2, has Kb= 4.2x10^-4. CH3NH2 + H2O -> CH3NH3+ + OH- Calculate the equilibrium hydroxide ion concentration in a 0.95 M solution of the base. [OH-] = What are the pH and pOH of the solution?
What is the Kb for methylamine, CH3NH2, if a solution prepared by dissolved 0.82 mol of methylamine in 425 mL of H2O has a pH of 12.46? (Ans: 4.4 x 10-4) A 0.100 M solution of formic acid, HCOOH, is 4.0% dissociated. Calculate Ka for formic acid. (Ans: 1.7 x 10-4)
Methylamine, CH3NH2, has a Kb = 4.40 x 10-4. What is the pH of a 0.250 M solution of methylamine?
A) Calculate the pH of a 0.0116 M aqueous solution of methylamine (CH3NH2, Kb = 4.2×10-4) and the equilibrium concentrations of the weak base and its conjugate acid. pH = ? [CH3NH2]equilibrium = ? M [CH3NH3+ ]equilibrium = ? M B)Calculate the pH of a 0.0115 M aqueous solution of nitrous acid (HNO2, Ka= 4.6×10-4) and the equilibrium concentrations of the weak acid and its conjugate base. pH = ? [HNO2]equilibrium = ? M [NO2- ]equilibrium = ? M C)...
