Gas Evolution Equations (Simplified) Practice Problems

At worst, when too much carbon dioxide is retained, a person can have respiratory acidosis. Then the person would have to expel the excess amount in any possible way to avoid complications. How does accumulating carbon dioxide cause the blood pH to decrease? Refer to the equation below.

H⁺ + HCO₃⁻ ⇌ H₂CO₃ ⇌ H₂O + CO₂

In respiratory alkalosis, a person hyperventilates. Consequently, more carbon dioxide is expelled than usual. How does the following chemical equation explain the change in the blood pH during hyperventilation?

H⁺ + HCO₃⁻ ⇌ H₂CO₃ ⇌ H₂O + CO₂

A volcanic eruption can be demonstrated using vinegar and baking soda. Foam and bubble overflow simulates the eruption. How are the foam and bubble formed when baking soda solution is mixed with vinegar? Which substance can be used as an antacid?

Write the complete balanced equation for the following gas-evolution reaction:

Na₂SO₃ (aq) + HCl (aq) →
