  Note :

  For technical reasons, chemists state that a solution in which the acid ions are equal in number to the basic or alkaline ions, has a pH of 7 and is neutral in reaction. Different numerical values indicate different degrees of acidity or alkalinity, much as the numbers on the thermometer scale indicate degrees of temperature. A pH of less than 7 indicates acidity, a number greater than 7 indicates alkalinity.
