1. A 100 mL sample of hydrazoic acid, HN₃(aq) with a concentration 0.25 mol/L has a pH of 2.78. Calculate the K_a for hydrazoic acid. Remember, when calculating the Ka, do not round off any of the numbers until the very end of the calculation!.

2. Calculate the pH of a 0.025 mol/L solution of magnesium hydroxide.

3. Calculate the pH of a 0.025 mol/L solution of sodium nitrite.

4. Hydrazine, N₂H₄(aq), is used in the preparation of polymers, pharmaceuticals and rocket fuel. Hydrazine has alkaline properties similar to ammonia and will act as a weak base. Given that a 100 mL sample of 0.10 mol/L hydrazine solution has a pH of 10.55 at 25.0 ^oC, write the formula for the conjugate acid and calculate the Ka of the conjugate acid.

Formula for the conjugate acid of hydrazine:

Calculate the Ka of the conjugate acid:
