Question

An antacid tablet requires 25.82 ml of 0.200 M HCl to titrate to its endpoint. What volume in ml of stomach acid can be neutralized by the antacid tablet? Assume the stomach acid as a pH of 1.10.

Answer 1

Convert stomach acid pH to concentration of H+.

Then 25.82 ml x 0.200 = amount of H+ neutralised by tablet,

and

amount neutralised by tablet = volume of stomach acid neutralised x concentration of H+ in stomach acid
