NaCl was used to rinse a condenser after distillation of 4-methylcyclohexene to remove unreacted phosphoric acid. Why is saturated NaCl used to rinse the glassware rather than water?

Answer 1

Was the stream of "waste" water allowed to drain into the freshly prepared 4-methylcyclohexene? Or were the rinsings dumped in the drain and/or otherwise disposed of.
