Question

NaCl is purified by adding HCl to a saturated solution of NaCl (317 g/L). Will pure NaCl precipitate when 30 mL of 4.5 M HCl is added to 0.15 L of saturated solution? Group of answer choices NaCl will precipitate from solution No NaCl will precipitate

Answer 1

The thing which will happen when NaCl is purified by adding HCl to a saturated solution of NaCl (317 g/L) is

• NaCl will not precipitate.

What is a Saturated Solution?

This refers to the type of solution which has a lot of solute that enables the solution to dissolve.

Hence, if NaCl is purified by the addition of HCl to a saturated solution of NaCl (317 g/L) and 30 mL of 4.5 M HCl is added to 0.15 L of saturated solution, then the NaCl will not precipitate because it cannot be transformed the dissolved substance to an insoluble solid as a result of the extra HCL added.
