Question

Mgso4 gives precipitate with nh4oh but not with nh4cl and nh4oh

Answer 1

Answer:

with mg so4 react with nh4 oh to give mg oh2 which is ppt. but with nh4 cl,it form mgcl2 which is a salt and do not ppt

Answer 2

MgSO4 reacts with NH4OH to form white coloured Mg(OH) precipitate.

• The reaction between magnesium sulphate and ammonium hydroxide is a double displacement where the magnesium forms an ionic bond with hydroxide ion (OH-) to form insoluble precipitate.
• With ammonium chloride (NH4Cl), double displacement again leads to formation of magnesium chloride (MgCl2) which is a soluble salt.
• Hence, MgSO4 forms precipitate with NH4OH but not with NH4Cl.
