A 0.333 g-sample of antacid was dissoived in 40.00 mL of 0.135 MHCI solution, then back-titrated to the end-point with 9.28 mL of a0.0203 M NaOH solution.d) How many moles of HCl reacted with the antacid sample?

Answer:

1 mole of HCl

Explanations

The balanced chemical reaction between the antacid sample (NaOH) and hydrochloric solution (HCl) is given as;


\text{NaOH+HCl}\rightarrow NaCl+H_2O_{}

From the balanced reaction, we can see that 1 mole of HCl reacted with 1 mole of the antacid sample according to the stoichiometry ratio.

Hence we can conclude that 1 mole of HCl reacted with the antacid sample during the chemical reaction
