Question

Write dissociation equations for the following soluble salts dissolving in water. Then draw a particle - level representation for each (omit water molecules). (a) NaBr (b) ZnCl2

Answer 1

The dissociation equations for NaBr gives Na+ and Br-

The dissociation equations for ZnCl2 gives Zn2+ and 2 Cl-

Step-by-step explanation:

The following pictures shows that the dissociation of one particle of NaBr produces one particle of Na+ (sodium cation) and one particle of Br- (bromine anion).

The dissociation of one particle of ZnCl2 produces one particle of Zn+2 (Zinc cation) and two particles of Cl- (chlorine anion).
