Of the following substances, an aqueous solution of will form basic solutions. NH4Br Pb(NO3)2 K2CO3 NaF

The compounds capable to form basic solutions are and NaF. Thus, options C and D are correct.

The basic solution has been given with the presence of a high number of hydroxide ions, while the acidic solution has been the presence of hydrogen ions.

The solution has been considered as basic when the compound has been constituted of a strong base. The constituents of the following compounds have been:

K2CO3  and NaF

Explanation:

In order to ascertain which salt would form a basic solution we have to identify the classification of each of the salts.

- NH4Br: is the salt of a weak base (NH3) and a strong acid (HBr). This means that it would form an acidic solution.

- Pb(NO3): This is a normal salt, hence would not form a basic solution.

-  K2CO3: This is salt that forms a strongly alkaline/basic solution.

- NaF: it is the salt of a strong base, NaOH, and a weak acid, HF. This means this would form a basic solution.
