Vedclass · Answer

(NONE) Statement $A$ is correct: In the Solvay process,$NaHCO_3$ precipitates because it is sparingly soluble in water. However,$KHCO_3$ is highly soluble in water,so it does not precipitate,making the Solvay process unsuitable for $K_2CO_3$ production.Statement $B$ is correct: Alkali metals dissolve in liquid ammonia to form a deep blue solution due to the presence of ammoniated electrons.Statement $C$ is correct: Heating $MgCl_2 \cdot 6H_2O$ leads to hydrolysis,forming $Mg(OH)Cl$ or $MgO$ instead of anhydrous $MgCl_2$.Statement $D$ is correct: Magnesium hydroxide suspension in water is known as milk of magnesia and acts as a mild antacid.
