Question

When an ionic compound dissolves in water:_________.

Answer 1

Answer:

a. the negative ends of water molecules surround the positive ions.

Explanation:

Ionization reaction is defined as the reaction in which an ionic compound dissociates into its ions when dissolved in aqueous solution.

Thus,

$NaCl_{(s)}\rightarrow Na^+_{(aq)}+Cl^-_{(aq)}$

When the ionic compound dissociates, the cation which is positively charged gets attracted to the oxygen (Negative ends) which is present in the water. The anion which is negatively charged gets attracted to the hydrogen (Positive ends) of the water.

Hence, the correct option is:- a. the negative ends of water molecules surround the positive ions.
