A solution is prepared by combining 3.227g of HN, (hydrazoic acid) with 1.442g of hydrazine (N.Н.) in 1 50mL of water at 25°C. The addition of the solids to the water did not cause a significant volume change. Calculate the equilibrium concentrations of HN,, N,H, N,, and N,H at 25°C Calculate the pH of the solution at 25°C (the bulk of the points comes from this part)
