Statement-1 :`V` group basic radicals are precipitated as their carbon

1.	Statement-1 :`V` group basic radicals are precipitated as their carbonates by `(NH_(4))_(2)CO_(3)` in presence of ammonia or ammonium chloride. Statement-2 :Aqueous ammonia maintains the `pH` of the solution basic.A. STATEMENT-1 is true, STATEMENT-2 is true and STATEMENT-2 is correct explanation for STATEMENT-1B. STATEMENT-1 is true, STATEMENT-2 is true and STATEMENT-2 is not correct explanation for STATEMENT-2C. STATEMENT-1 is true, STATEMENT-2 is falseD. STATEMENT-1 is false, STATEMENT-2 is true
Answer» Correct Answer - B Statement-1 :In the presence of `NH_(4)^(+)` salts, no precipitation of `Mg^(2+)` occurs because the equilibrium `NH_(4)^(+) + CO_(3)^(2-) hArr NH_(3) +HCO_(3)^(-)` is shifted towards the formation of `HCO_(3)^(-)` ions. `K_(sp)` of the precipitate being high (`K_(sp)` of pure `MgCO_(3)` is `1xx10^(-5)`), the concentration of carbonate ions necessary to produce a precipitate is not attained. Statement-2 :`NH_(4)OH` turns red litmus blue.`NH_(4)OH hArr NH_(4)^(+) +OH^(-)`
