Ph of 1m hf

Webb14 nov. 2024 · Answer: The pH is 3.57. Explanation: Step 1: Data given Volume = 1.50 L. Molarity of HF = 0.250 M. Molarity of NaF = 0.250 M. addition of 0.05 moles NaOH. Step 2: The buffer contains HF, which is a weak acid; and NaF, which is the salt of its conjugate base, the fluoride anion, F. Webb1M solution of NaOH. Detailed Solution for Test: Common Ion Effect - Question 3. The correct answer is Option B. NH4Cl is a strong electrolyte hence, dissociates completely, NH4OH is a weak electrolyte. Its dissociation is further suppressed by common ion NH4+ provided by NH4Cl in the solution. NH4Claq ⇌ NH4aq+ +Claq−.
