Answer to Question #310390 in General Chemistry for jay

Question

Show your solution:A soda mint tablet contains NaHCO3 as an antacid. One tablet requires 30.5 mL of 0.135 M HCI for complete reaction. Determine the number of grams of NaHCO3 that one tablet contains. The chemical equation for the reaction is:

NaHCO (s)+HCI (aq)- NaCI (aq)+CO2 (g)+ H2O (I)

Answer 1

One table requires 30.5 mL of 0.135 M HCl

Mole of HCl require = 0.041175 mole

The given reaction as follws

$NaHCO_3 (s) +HCl(aq) \longrightarrow NaCl(aq)+CO_2(g) +H_2O(l)$

One Sodium bicarbonate producea one mole soda bicarbonate

Mole of bicarbonate = 0.041175 mole

Mass of bicarbonate = 3.4587 g

So, one soda mint tablet has 3.4587 g of sodium bicarbonate
