Effect of HCl on NaCl crystallization rate

[DrBanana]

TL;DR

Was wondering if and how HCl affected how fast NaCl crystals form.

I came across a book that said if you add HCl (acid) to a saturated NaCl solution, then the crystallization process of that salt will be accelerated. Is this true, and if so, how?

Edit: As it is with these things, I find the solution immediately after making this post. Here is a youtube video:

Hello @DrBanana ,

The common ion effect is when you add more of one ion and that pushes the equilibrium to the side that removes the ions you have added (le Chatelier effect). Precipitation removes the NaCl from solution. People forget that disolving ionic things is an equilibrium where the solid dissociates into ions in solution and the normal le Chatelier rules apply.
