SUMMARY
The discussion focuses on calculating the molar concentration of sodium cations in a mixture of sodium hydroxide and sodium sulfate solutions. The initial concentration of sodium hydroxide is 0.200 mol dm-3 in a volume of 15 cm3, yielding 0.003 moles of sodium ions. The sodium sulfate solution has a concentration of 0.120 mol dm-3, and the total volume of the resultant mixture is 100 cm3. The challenge lies in determining the volume of sodium sulfate added to achieve the final concentration of sodium cations.
