a solution is made by combining 10.0 ml of 17.5 M acetic acid with 5.54 g of sodium acetate and diluting to a total volume of 1.50 L.
a)calculate the pH of the solution.
b) how many grams and milliliters of 14.6 M potassium hydroxide needs to be added so pH=pKa?
c)what is the pH of the solution when 100ml of a 2.25 M HCL is added to the original buffer solution?
