Question

Write the ions present in a solution of na3po4. express your answers as chemical formulas separated by a comma. offset subscripts and charges on each ion.

Answer 1

Sodium/natrium is a metal from first column group so it should have one 1+ charge. Phosphate ion has 3- charge. That is why there 3 natrium ion for 1 phosphate ion when this molecule is dissolved in water. The ion formula would be:

(Na)$_{3}$(PO$_{4}$) ==> 3 Na$^{+}$   +  PO$_{4} ^{3-}$
