WebbWhen pH or pOH of solution is known, we can readily calculate concentrations of hydronium ion (H 3 O +) or hydroxyl ion (OH -) using the pH equation. Also, in this online pH calculator, you have to just substitute pH or pOH value and it will give you what is the H 3 O + ion concentration of aqueous solution. Webbsolution, in chemistry, a homogenous mixture of two or more substances in relative amounts that can be varied continuously up to what is called the limit of solubility. The term solution is commonly applied to the liquid state of matter, but solutions of gases and solids are possible.

For example, it is tedious to keep saying that the concentration of hydrogen ion– [H+] — in water at 25 °C is 0.0000001 moles per liter. If this same value is written in standard notation, we will get 10 -7 moles per liter.
