A neutral solution has an equal number or concentration of hydrogen and hydroxide ions. A neutral solution is one that has a pH of 7.0. Pure water is a neutral solution.
Water (H2O)
A base will form hydroxide ions in a solution.
At pH 7, the concentration of hydroxide and hydrogen (hydronium) ions is equal; both concentrations are equal to 10-7 mol/L.
A solution that contains equal concentrations of hydrogen and hydroxide ions is neutral. Water is the prime example.

salt ions and water and an equal amount of hydrogen and hydroxide ions.
In an acidic solution, the relative concentration of hydronium ions will always be higher than hydroxide ions. This means that the relatively concentration of hydroxide ions will always be lower than hydronium ions in an acidic solution. The reason for this is that in a neutral solution, the concentration of both hydronium ions and hydroxides ions are equal (both are 10-7). By making the concentration of hydronium ions greater than the concentration of hydroxide ions, the solution becomes acidic.
A base in solution will produce hydroxide or OH- ions.
The conclusion that can be made about the portion of hydroxide ions and hydrogen ions in a solution that has a pH of 7 is that they are equal. The quantities pH + pOH, which are derived from the concentrations of hydroxide and hydrogen ions, will always have a sum of 14. The ratio of hydrogen and hydroxide in a single water molecule is 1:1.
At pH 7, the concentration of hydroxide and hydrogen (hydronium) ions is equal; both concentrations are equal to 10-7 mol/L.
A solution that contains equal concentrations of hydrogen and hydroxide ions is neutral. Water is the prime example.
Technically it is called water because the positive hydrogen ions and the negative hydroxide ions would attract to form a compound with two hydrogen molecules and one oxygen molecule. H2O. This occurs most often in acid-base neutralization reaction where water is a product of the reactions.
pH is a measure of the concentration of hydronium ions in a solution. pOH is a measure of the concentration of hydroxide ions in a solution. When a salt is placed into a solution (typically an aqueous solution), the cation and anion can either dissociate completely or partially, and can react with other ions in solution. If the salt pulls hydroxide ions out of solution, the solution becomes more acidic, and if the salt pulls hydronium ions out of solution, the solution will become more basic. So, if you want to determine the "strength" of a salt, add it to water and measure the hydronium ion concentration of that solution.
It produces a neutral salt along with water
