When hydrazine is dissolved in water, it acts like a base.

a. Calculate the Kb for the overall reaction of hydrazine forming N₂H₆²⁺.

b. Calculate K_a1 for N₂H₅⁺.

c. Calculate the concentration of hydrazine and both cations in a solution buffered at a pH of 8.5 for a solution that was made by dissolving 0.012 mol of hydrazine in 1 L of water.
