Question

50.00 mL of OOH was diluted to 250.0 mL with deionized water. In the determination of the total cation concentration, 25.00 mL aliquots of the dilute OOH were passed through a cation exchange column and the eluent titrated with an average 27.42 mL of 0.1134 M NaOH. In the determination of calcium and magnesium ions, 25.00 mL aliquots of the dilute OOH were titrated with an average 34.03 mL of 0.01018 M EDTA. Determine the sodium, magnesium and calcium ions concentrations in the undilute OOH, noting that the ratio of magnesium to calcium ions in OOH is about 3:2.

Answer 1

Does OOH have a name? It's a new one on me.

Answer 2

Ogre's ocean water apparently
