You could boil away the water, evaporating it, and leaving behind the solute.
Physical changes occur when the properties of a substance are retained and/or the materials can be recovered after the change. Chemical changes involve the formation of a new substance. Formation of a gas, solid, light, or heat are possible evidence of chemical change.

Answer:
1)NH4ClO4: acidic
2)NH4CN: basic
3)LiF: basic
4)KCN: basic
5)LiNO3: neutral
6)NH4Br: acidic
7)SrBr2: neutral
Explanation:
Salt is an ionic compound formed by the neutralization reaction between an acid and a base.The cation of base and anion from an acid combines to form a salt while H+ from acid and OH- from base forms water.
1)NH4Cl4: is an acidic salt formed from neutralization reaction between strong acid and a weak base.
2)NH4CN: is a basic salt formed from neutralization reaction between weak acid and weak base.
3)LiF: basic salt formed from neutralization reaction between strong acid and strong base.
4)KCN: basic salt formed from neutralization reaction between weak acid and strong base.
5)LiNO3: neutral salt formed from neutralization reaction between strong acid and strong base.
6)NH4Br: acidic salt formed from neutralization reaction between strong acid and weak base.
7)SrBr2: neutral acid formed from neutralization reaction between
strong acid and strong base.
