Sodium ion (Na+) and calcium ion (Ca2+) produce nearly the same color in a flame test (yellow and yellow-orange, respectively). Describe a way to differentiate between the two using a solution of Na2CO3 and write the correct balanced equation(s).

Sodium ion (Na+) and calcium ion (Ca2+) produce nearly the same color in a flame test. So you'll get 2 equations:
1) Na2CO3+2Na+→ Na2CO3+2Na+. It's referred to Na+
2) Ca2++Na2CO3→CaCO3+2Na. It's to Ca2+.
Hope, you'll find it useful.
