How would you prepare :
sodium hydrogen carbonate crystals.

✓

Answer

Sodium hydrogen carbonate crystals :
Dissolve $5$ grams of anhydrous sodium carbonate in about 25 ml of distilled water in a flask. Cool the solution by keeping the flask in a freezing mixture. Pass carbon dioxide gas in the solution. Crystals of sodium bicarbonate will precipitate out after sometime. Filter the crystals and dry it in folds of filter paper.
Reaction : $Na_2CO_3 + CO_2 + H_2O ⟶ 2NaHCO_3$
