1.	Aqueous ammonia is used as a precipitating reagent for `Al^(3+)` ions as `Al(OH)_(3)` rather than aqueous NaOH, becauseA. `NH_(4)^(+)` is a weak baseB. `NaOH` is a very strong baseC. NaOH form `[Al(OH)_(4)]^(-)` ionsD. NaOH forms `[Al(OH)_(2)]^(+)` ions
Answer» Correct Answer - C `Al(OH)_(3)+OH^(-) overset(NaOH)rarr [Al(OH)_(4)]^(-)`
