Question 4 (8 points) 150.00 mL of 1.50 mol/L methanoic acid is being titrated with 0.750 mol/L sodium hydroxide. What is the pH after 30.00 mL of base has been added? (Ka = 1.78 x 10-4) OpH = 4.00 pH = 7.00 OpH = 0.14 pH = 2.80

Question 5 (6 points) A buffer solution is made from 0.650 mol/L ammonia and 0.350 mol/L ammonium chloride (to total 1L of liquid). What is the pH of this buffer? (Kb = 1.8 x 10-5) OpH = 4.48 OpH = 3.44 OpH=9.52 OpH=8.52

Question 6 (5 points) ✔ Saved What is the pH of a 0.340 mol/L solution of sodium fluoride? (Ka HF = 7.2 x 10-4) OpH-8.20 pH-5.56 pH=8.34 OpH-3.02
