(a)
Interpretation:
For magnesium chloride the anion and cation along with charge must be identified.
Concept introduction:
Total charge of cation and anion in a compound must be 0.
The charge in each ion depends on the valency.

Answer to Problem SIV5RQ
The anion is chloride and charge is -1.
The cation is magnesium and charge is + 2.
Explanation of Solution
Magnesium chloride is an ionic salt which on dissociation produces magnesium cation (Mg + 2) and two chloride (Cl-) ions. Charge on cation is 2 units and charge on each anion is 1 unit. Thus, total charge of two chlorides is -2 which counterbalances the 2 unit positive charge of one magnesium ion.
(b)
Interpretation:
For calcium nitrate the anion and cation along with charge must be identified.
Concept introduction:
Total charge of cation and anion in a compound must be 0.
The charge in each ion depends on the valency.

Answer to Problem SIV5RQ
The anion is nitrate and charge is -1.
The cation is calcium and charge is + 2.
Explanation of Solution
Calcium nitrate is an ionic salt which on dissociation produces calcium cation (Ca + 2) and two nitrate (NO3-) ions. Charge on cation is 2 units and charge on each anion is 1 unit. Thus, total charge of two nitrates is -2 which counterbalances the 2 unit positive charge of one calcium ion.
