A student is given an antacid tablet that weighs 5.4630 g. The tablet is crushed and 4.3620 g of the antacid is added to 200. mL
Luda [366]

Solution :

It is given that :

Weight of the antacid tablet = 5.4630 g

4.3620 gram of antacid is crushed and is added to the stomach acid of 200 mL and is reacted.

25 mL of the stomach acid that is partially neutralized required 13.6 mL of NaOH to be titrated for a red end point.

27.7 mL of $NaOH$ solution is equivalent to $25 \ mL$ of the original stomach acid. Therefore, 13.6 mL of NaOH will take x $\frac{25\text{ mL of original stomach acid}}{\text{27.7 mL of NaOH}}$

                                                             = 12.27 ml of the original stomach acid.
