Concept explainers
(a)
Interpretation:
K+ should be combined with SO32- in order to derive an ionic compound with zero net charge.
Concept introduction:
An ionic compound is derived by forming an ionic bond between 2 oppositely charged ions. The cations & anions should be combined in a ratio that the net charge of the compound should be zero.
(b)
Interpretation:
Ba2+ should be combined with SO32- in order to derive an ionic compound with zero net charge.
Concept introduction:
An ionic compound is derived by forming an ionic bond between 2 oppositely charged ions. The cations & anions should be combined in a ratio that the net charge of the compound should be zero. If the charges are same in both, the combining ratio is 1: 1.
(c)
Interpretation:
Al3+ should be combined with SO32- in order to derive an ionic compound with zero net charge.
Concept introduction:
An ionic compound is derived by forming an ionic bond between 2 oppositely charged ions. The cations & anions should be combined in a ratio that the net charge of the compound should be zero. To obtain this charge neutrality multiple numbers of cations & anions can be combined.
(d)
Interpretation:
Zn2+ should be combined with SO32- in order to derive an ionic compound with zero net charge.
Concept introduction:
An ionic compound is derived by forming an ionic bond between 2 oppositely charged ions. This bond formation occurs through electrostatic attraction forces between 2 opposite charges. The cations & anions should be combined in a ratio that the net charge of the compound should be zero.
