If we have 300 mL of 1.25 Macetic acid and would like to achieve solution that has pH 4, how much sodium acetate (in grams) we need to add (Molar mass of sodium acetate is 82.0343 g/mol). Assume that the change in volume when the sodium acetate is added is not significant. The Ka for acetic acid is 1.7 x 10-5
