Question

Chemical name of $N{a_3}P{O_4}$ is sodium phosphate.
A) True
B) False

Answer 1

Hint: We can solve this question by naming the chemical compound according to its formula, which is determined by the number of atoms contained in the compound, and then naming it tri, di, hypo, bis, tris, and so on.

Complete answer: We have learned the basic concept of chemistry in school, which tells about the naming of chemical compounds based on rules such as the IUPAC rule, as well as the common names which were given to some of the compounds.

These laws can be used to name the above-mentioned compound:
1. We know that there are three atoms of sodium, one atom of phosphorus, and four atoms of oxygen in the formula $N{a_3}P{O_4}$.
2. The compound in question belongs to the alkali metal phosphate family of inorganic compounds. The phosphate group is represented by the $P{O_4}$ symbol.
3. We can conclude that the compound's last name is phosphate.
4. Since it contains three sodium atoms, it is given the prefix tri (meaning three). As a result, the final name for this compound is trisodium phosphate.

Since the compound can be identified by its common name, it can also be referred to as sodium phosphate, and the valency of the sodium atom found in this compound can be calculated using the phosphate group's formula.

The chemical name of $N{a_3}P{O_4}$ is sodium phosphate. The previous statement is true.
Hence the correct option is A) True.

Note:
Emulsifiers (as in processed cheese), thickening agents, and leavening agents for baked products are all popular uses for sodium phosphates. They are also used to keep the pH of processed foods in check. They are also used in medicine to treat constipation and clear the colon for surgery.
