Acidic, Basic or Neutral?

Build a salt from any cation and anion. The lab finds the reacting ion, runs the equilibrium and puts the pH on the strip.

The beaker the salt dissolves, then one ion goes to work

A dissolved salt and the ion that reacts with water

Pick the cation

Pick the anion

Verdict

7.00pH neutral
Salt: NaCl
Reacting ion: neither one
Constant used: none needed
Ion made by the reaction: none mol/L
Formula units per salt: 1 cation, 1 anion
Parent acid: HCl, strong
Parent base: NaOH, strong

The reaction that sets the pH

No hydrolysis. Both ions just float.

Sodium came from a strong base and chloride came from a strong acid. Neither has any pull on protons, so the water stays at pH 7.
