Abeaker has 0.2 m of na2so4. what will be the concentration of sodium and sulfate ions?
[na+] = 0.4 m, [so42-] = 0.2 m
[na+] = 0.2 m, [so42-] = 0.2 m
[na+] = 0.4 m, [so42-] = 0.4 m
[na+] = 0.2 m, [so42-] = 0.4 m

The concentration of sodium and sulphate ions are [] = 0.4 M, [] = 0.2 M

Explanation:

The molar concentration is defined as the number of moles of a molecule or an ion in 1 liter of a solution.

In the given solution, the concentration of the salt sodium sulphate is 0.2M. So, 0.2 moles of sodium sulphate is present in 1 liter of solution.

Assuming 100% dissociation,

1 molecule of sodium sulphate gives 2 ions of sodium and 1 ion of sulphate.

So 0.2 moles of sodium sulphate will give 0.4 moles of sodium ions and 0.2 moles of sulphate ions.

you gotta add the following molecules so we can give u an answer
