Magnesium content present in aqueous solution can be precipitated using either aqueous sodium carbonate or aqueous barium hydroxide .Write equation and discuss.

Explanation

`Mg^(2+)+Na_(2)CO_(3) to MgCO_(3) darr +2Na^(+)`
Sodium carbonate is water soluble but magnesium carbonate is almost insoluble in water
`Mg^(2+)+Ba(OH)_(2)toMg(OH)_(2) uarr +Ba^(2+)`
Barium hydroxide is water soluble , but magnesium hydroxide is almost insolublein water .
