Hydrogen ion concentration in a solution and pH scale

pH is the degree of acidity or basicity of a chemical substance in aqueous systems.

In simple terms pH is the power of hydrogen ion or hydronium ion concentration.
It can be calculated by :
pH = - log10[H+] or 
pH = - log10[H3O+
[ ] square bracket represents the concentration in mol/dm3
Example: If a sample of an acid is found to have[ H+]=1X10-4
Than pH = - log10[1X10-4]
pH = -[-4 log 10]
pH= 4
If you want to find out [ H+] than you can use the following formula: pH = 10-pH
