WebThe pH of a system is a measure of the amount of free hydrogen ions in solution, as given by the following formula: pH = -log [H+]. Notice that at higher concentrations of H+, the value of the pH will get smaller. Sodium carbonate is not soluble (sodium is an alkali metal), and thus dissolves in solution: book hayfever injection
