Question

1. Calculate the volume in mL of a 0.50 M NaOH solution that will be required to titrate 1.2 g of potassium hydrogen phthalate to the phenolphthalein end point. The molar mass of KHP is 204.2 g/mol

2. It takes 12.45 mL of 0.50 M NaOH to back titrate a mixture containing 1.25 g of baking soda, NaHCO₃, and 10.00 mL of 1.2 M HCl solution. Calculate the moles of antacid activity (OH^-) per gram of baking soda.
