Confusion on Friday's lecture

Hi!

For last Friday's lecture I wrote down in my notes that: Cl- is "good on its own" in a solution as shown by the equation HCl --> H+ + Cl-
I'm a bit confused by this though, how can we know Cl- won't affect the reaction through this equation? Is this also why Cl- doesn't affect the pH of water?

Thank you!!

As I discussed in class. Think of adding salt to water. :-)

Na+Cl- dissolves in water and each are stable as Na+ and Cl- solvated (surrounded) by water molecules.

There are no additional reactions and therefore both Na+ and Cl- do not change the pH of water.

Thank you Dr. Lavelle! :)
