Would salt in the soil be the reason I am getting a Ph reading of 9 in the soil around my salt water pool?

Salt, as I said earlier is made up of sodium ions and chloride ions. Both sodium and Chlorine are chemical elements and an ion is a charged
atom or molecule. Atoms can be broken down only into electrons, protons and (neutrons). These are the particles that make up all the elements.
When an ionic compound, such as salt, is dissolved in water, it breaks down into its ions.
Sodium and chloride ions being ions of chemical elements can only be broken down into electrons, protons and neutrons, and to do so requires a hell lot of
energy.
Sodium Chloride is a neutral salt, that is, it is a product of netralization of a strong acid, hydrochloric acid, with a strong alkali, sodium hydroxide.
This is manifested in the pH of salt solutions in water (also called aqueous solution) to be 7 at room temperature. All aqueos solutions that have a pH 7 are neutral. So if you are getting a pH 9 for your soil, it is basic (alkaline) and this higher pH cannot be due to the presence of salt alone.
To bring down the pH of your soil, you may add to it some acidic salt, say ammonium chloride.
