Question

NaCl is purified by adding HCl to a saturated solution of NaCl (317 g/L). Will pure NaCl precipitate when 10mL of 13.0 M HCl is added to 0.2 L of saturated solution? Group of answer choices NaCl will precipitate from solution No NaCl will precipitate

Answer 1

No, pure NaCl will not precipitate from the solution.

Step-by-step explanation:

To determine whether pure NaCl will precipitate when 10mL of 13.0 M HCl is added to 0.2 L of a saturated solution of NaCl (317 g/L), we need to compare the solubility product (Ksp) of NaCl and the reaction quotient (Q). The solubility product of NaCl is very high, indicating that it is highly soluble in water. When HCl is added to the saturated solution, it dissociates into H+ and Cl- ions. The addition of HCl does not change the concentration of Na+ and Cl- ions, therefore the concentration of NaCl is not affected and no precipitation will occur.
