Problem 81P

PROBLEM 81P

Sodium bicarbonate is often used as an antacid to neutralize excess hydrochloric acid in an upset stomach. How much hydrochloric acid in grams can be neutralized by 3.5 g of sodium bicarbonate? (Hint: Begin by writing a balanced equation for the reaction between aqueous sodium bicarbonate and aqueous hydrochloric acid.)

Step-by-Step Solution:

Solution 81P :

Step 1:

Here, we have to find, the amount of hydrochloric acid in grams that can be neutralized by 3.5 g of sodium bicarbonate

The balanced double displacement equation for the chemical reaction here is :

        NaHCO3(aq) + HCl(aq) → NaCl(aq) + H2O(l) + CO2(gas)

In the reaction we see that, 1 mole of NaHCO3 neutralizes 1 mole of HCl.

Let’s calculate number of moles in 3.5 g of NaHCO3:

        

        Number of moles (n) =

Molar mass NaHCO3 = 84.007 g/mol

                n =

= 0.0416 mole
