100%
I don't understand what my teacher is trying to explain here. Why is the concentration 0. If only one concentration is possible does that mean it's always zero?

Solution
• In 0.010 M Na,SO4:
- two moles of Na* ions are formed for each
mole of Na,SO, in solution, so [Na*] =
0.020 M.
one mole of SO,²- ion is formed for each
mole of Na,SO, in solution, so [S0,²] =

0.010 M.
An ion can have only one concentration
in a solution, even if the ion has two or
more sources.
