Question

Indicate whether aqueous solutions of each of the following solutes will contain only ions, only molecules, or mostly molecules and a few ions:
a) NH4Cl, a strong electrolyte.
b) Ethanol, CH3-CH2-OH, a nonelectrolyte.
c) HCN, hydrocyanic acid, a weak electrolyte.

Answer 1

Answer:

Following are the solution to the given points:

Explanation:

In point a, the answer is only ions because of $NH_4Cl$ has a strong electrolyte.

In point b, the answer is the only molecules because of ethanol $CH_3CH_2OH$, it has a nonelectrolyte.

In point c, the answer is the few ions because of hydrocyanic acid HCN, which has a weak electrolyte.
