Answer:
Ethanol
Step-by-step explanation:
As we know , magnesium nitrate is an ionic compound , because in water it easily dissociate into its corresponding ions , i.e. , Mg²⁺ and NO₃⁻ ions .
So , by using water as a solvent , will not work for Magnesium nitrate .
Hence ,
Ethanol can possibly be used as the solvent for the reaction of dilute magnesium nitrate , because , it is very less soluble in ethanol .
