Methyl orange acts as a pH indicator in the process of sodium carbonate and hydrogen chloride titration. The addition of methyl orange will indicate the ratio of sodium carbonate to hydrogen chloride by the colour which develops.
Sodium Chloride (salt), Carbon Dioxide, and Water
CaCO3 + 2(HCl) = H2O + CO2 + CaCl2 so Calcium carbonate + hydrogen chloride yields water and carbon dioxide and Calcium chloride
You will get a positive result for hydrogen because the reaction of zinc and hydrochloric acid produces zinc chloride and hydrogen. The chlorine atoms from the hydrochloric acid attach to the zinc, leaving the hydrogen behind and thus, you have hydrogen.
Hydrogen Chloride gas --> HCl or Hydrochloric Acid --> HCl(aq)
Firstly, they'll react each other forming sodium hydrogen carbonate and sodium chloride. If there is excess HCl, the sodium hydrogen carbonate would further react till sodium chloride and evolve carbon dioxide.

This is hydrogen.
Any reaction occur.

Examples: sodium chloride, potassium chloride, calcium chloride, sodium hydrogen carbonate, sodium citrate, potassium permanganate, magnesium sulfate etc.

Baking soda is sodium hydrogen carbonate - NaHCO3.
The insoluble salt barium sulfate is obtained.

When u mix calcium chloride&sodium carbonate u get calcium carbonate,which turns lime water milky wen calcium hydrogen trioxocarbonate and sodium chloride i.e cacl2 + Naco3--caco3 +2Nacl.
