Problem: Hydrazine (NH2NH2) has a Kb = 3.0 x 10-6. If 100.0 mL of a 0.5000 M aqueous hydrazine solution is mixed with 100.0 mL of 0.5000 M aqueous hydrochloric acid, the resulting solution will have a pHa. pH > 7b. pH < 7c. pH = 7

FREE Expert Solution

We are being asked to determine if the pH is less than, greater than or equal to 7 when 100.0 mL of a 0.5000 M NH2NHis mixed with 100.0 mL of 0.5000 M HCl

Upon inspection, NH2NHappears to be a weak base (amines are weak bases) while HCl is a strong acid
