Consider the equation below.
na+ + cl– (to) nacl
which statement best describes the relationship between the substances in the equation?
a. the number of sodium ions is equal to the number of formula units of salt.
b. the number of sodium ions is less than the number of chloride ions.
c. the number of chloride ions is less than the number of formula units of salt.
d. the number of sodium ions is two times the number of formula units of salt.

The answer is: a. The number of sodium ions is equal to the number of formula units of salt.

Balanced chemical equation: Na⁺ + Cl⁻ → NaCl.

Formula unit is the representative particle of an ionic compound. It is lowest whole number ratio of ions in an ionic compound, for sodium chloride it is NaCl.

In this chemical equation one sodium cation and one chlorine anion form one sodium chloride formula unit.

answer is A=The number of sodium ions is equal to the number of formula units of salt.
