1.	A metal M reacts with sodium hydroxide to give a white precipitate X which is soluble in excess of NaOH to give Y. Compound X is soluble in HCI to form a compound Z. Identify M.X,Y and Z M , X , Y, Z
Answer» `Si, SiO_(2),Na_(2)siO_(3),SiCI_(4)` `AI, AiI(OH)_(3),NaMgO_(3),AICI_(3)` `Mg,Mg(Oh)_(3),NaMgO_(3),MgCI_(2)` `Ca,Ca(OH)_(2) ,Na_(2) CO_(3),NaHCO_(3)` Solution :`underset((M))(2AI) + 2NaOH + 6H_(2)O to underset((X))(2AI(OH)_(3)) underset(NaOH)overset("Excess of")(to) underset((Y))(NaAIO_(2))` `underset((X))(2AI(OH)_(3)) 6HCI to underset((Z))(2AICI_(3)) + 6H_(2) O`
