Verified step by step guidance1
Identify the ions involved in sodium sulfate: sodium ion (Na\^+) and sulfate ion (SO\_4\^{2-}).
Determine the charge on each ion: sodium ion has a +1 charge, sulfate ion has a -2 charge.
Balance the total positive and negative charges to make the compound electrically neutral.
Since sulfate has a -2 charge, two sodium ions (each +1) are needed to balance the charge.
Combine the ions to write the formula: two sodium ions and one sulfate ion give the formula Na\_2SO\_4.
