Question

a student added dilute hydrochloric acid to sodium hydrogen carbonate the evolved gas was passed through lime water what change would be observed in lime water write balanced equations for both the reactions

Answer 1

Explanation:

NaHCO3 + HCL —→Nacl + H2O + CO2

Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O. .

Answer 2

Answer:

When dilute HCl, which is an acid, added to sodium carbonate, a strong base, the neutralization reaction occurs by the formation of NaCl and the evolution of carbon dioxide gas by brisk effervescence.

2HCl+Na
