Question

How many moles of bicarbonate were consumed in a reaction with acetic acid if 0.3

moles of CO2 were produced?

Answer 1

= 0.3 moles bicarbonate

Step-by-step explanation:

• Carbonates and bicarbonates react with acids to form water, salt, and carbon dioxide.
• The reaction between bicarbonate and acetic acid is given by the equation;
• HCO₃ + CH₃COOH → CH₃COONa + H₂O + CO₂
• To calculate the number of moles of the bicarbonate we use the following steps.

Step 1: Write a balanced equation between Acetic acid and bicarbonate

• The balanced equation between acetic acid and the bicarbonate is;

NaHCO₃(s) + CH₃COOH(aq) → CH₃COONa(aq) + H₂O(l) + CO₂(g)

Step 2: Moles of bicarbonate

We use the mole ratio of bicarbonate to carbon dioxide

Mole ratio = 1: 1

Therefore, the moles of the bicarbonate is 0.3 moles
