If 100. mL of 0.100 M K2SO4 is added to 200. mL of 0.150 M KCl, what is the concentration of K + ions in the final solution? Assume that the volumes are additive.

The final concentration will be "0.167 M".

According to the question,

Moles of KCl,

Moles of K₂SO₄,

Total moles of K+ will be:

=

Total volume will be:

=

hence,

→ The final concentration of K+ will be:

=

=

=

=

Thus the above solution is correct.
