Answer #1

Sodium bicarbonate (NaHCO3) is base. It can be used to wash to remove any acidic impurities. Since it is base , reaction with acid impurites easier one to happen. If any organic layers ( compounds or liquids) contains acid impurities ( preferely weak acid or dilute acids), you can was with satuated NaHCO3 solution to getrid of acid impurites.

Reaction of NaHCO3 with any acid to produce a salt and CO2

CH3COOH + NaHCO3 → CH3COONa + CO2 + H2O

carbon dioxide(CO2) gas evolves when washing( reacting) with sodium bicarbonate

Sodium Bicarbonate is used to neutrailze acids to form sodium chloride, a salt, carbon dioxide gas, and water. Normally sodium bicarbonate is added until the fizzing ceases, at which point no more CO2(g) is produced. NaHCO3(s) + HCL (aq) -> NaCl (aq) + CO2(g) +h2O (l) If 100ml of 6 M HCL is spilled on a lab bench what is the minimum mass of sodium bicarbonate that must be used to neutralize the acid ? Thank you !
