WebSalts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, … Webwhere [H +] is the equilibrium molar concentration (mol dm −3) of H + in the solution. At 25 °C (77°F), solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic. Solutions with a pH of 7 at this temperature are neutral (i.e. have the same concentration of H + ions as OH − ions, i.e. the same as pure water).
