Question

how does a blue litmus turn red when carbon di oxide react with water give a balanced equation​

Answer 1

Answer:

CO2(aq) + H2O(l) ⇌ H+(aq) + HCO3–(aq)

2NaOH(aq) + CO2(g) → Na2CO3(aq) + H2O(l)

Bases have a tendency to convert the redlitmus blue, as the compound formed by bases when dissolved or reacted with water, litmus blue. Few examples of bases are sodium hydroxide and calcium carbonate.gives out hydroxide ion, therefore turning red
