Question

what is the ratio of sodium ions to bromide ions in neutral sodium bromide?
1:1
2:1
2:3
3:2

Explanation:

Step1: Write the chemical formula

Sodium bromide's chemical formula is $NaBr$.

Step2: Analyze ion - composition

In $NaBr$, sodium ion is $Na^{+}$ and bromide ion is $Br^{-}$. One $NaBr$ molecule dissociates into one $Na^{+}$ and one $Br^{-}$. So the ratio of sodium ions to bromide ions is 1:1.

Answer:

A. 1:1
