Explain phenolphthalein is added and the solution colorless

Reference no: EM13274066

27.0 mL of 0.11 M HCl is added to 0.57 g of commerical antacid. Some, not all, of the added acid is neutralized by the antacid. Phenolphthalein is added, and the solution remains colorless because of the excess acid that has not been neutralized. the solution is tirtared with 9.7 mL of 0.09 M NaOH to a faint pink endpoint. if an entie tablet of this antacid has a mass of 1.37 g, how many moles of HCl will be neutralized by one tablet of this antacid?
