Write the correct chemical formula for barium nitrate. What is
the ratio of barium ions to nitrate ions?
The correct chemical formula for barium nitrate is Ba(NO3)2.
To determine the ratio of barium ions to nitrate ions, we look at the subscripts in the chemical formula. In this case, there is one barium ion (Ba) and two nitrate ions (NO3) present.
Therefore, the ratio of barium ions to nitrate ions is 1:2.
Ba(NO3)2.
1 Ba to 2 nitrate.
