Your friend brings you a 1.50 M sample of HONH3Cl and wants yo know the pH. You politely ask for the Ka of the acid and she responds that she only knows that the Kb for HONH2 = 3.0 x 10^-6
(A) Write an equation for the equilibrium reaction and a K expression.
(B) Solve for the pH of the solution.
To a second 25.00 mL part, 10.00 mg of lead was added and extracted into a second 10.00 mL portion of the same organic solvent. This solution gave A = 0.525. What was the concentration of lead, in mg/mL, in the original sample?
