A student used a cation exchange resin to determine themolarity of sodium ion in an unknown sodium chloride solution. Thestudent diluted the 25.00mL aliquot of the original unknown solution to 250.0mL in a volumetric flask. After passing a 50.00mLaliquot of the dilute unknown sodium chloride solution through acation exchange resin, 30.00mL of 0.010M sodium hydroxide solution were required to titrate the eluatea)
1. Calculate the molarity of sodium ion in the 50.00mL portionof the diluted unknown sodium chloride solution.
2. Calculate the molarity of sodium ion in the original sodium chloride solution.
