Question

write the formula for the sodium carbonate ion.

• subscripts and superscripts are not supported in answer boxes so they are in normal script.

○ so4^2- is written as so4^2-
○ na2so4 is written as na2so4

Explanation:

Step1: Determine the ions involved

Sodium ion is \(Na^+\), carbonate ion is \(CO_3^{2 -}\).

Step2: Balance the charges

To balance the +1 charge of \(Na^+\) and - 2 charge of \(CO_3^{2 -}\), we need 2 \(Na^+\) ions.

Answer:

\(Na2CO3\)
