Answer:
Explanation:
In chemistry, efflorescence (which means "to flower out" in French) is the migration of a salt to the surface of a porous material, where it forms a coating.
Example:Sodium carbonate deca hydrate (Na2CO3.10H2O) will lose water when exposed to air.
Effervescence is the escape of gas from an aqueous solution and the foaming or fizzing that results from that release.
Example:{\displaystyle {\ce {H2CO3 -> H2O + CO2 (^)}}}
In simple terms, it is the result of the chemical reaction occurring in the liquid which produces gases.
