Defination / Uses

Buffer is a solution made up of a weak acid and its conjugate base that can be utilized to keep a solution's pH stable. The pH of aqueous or other liquid solutions is a quantitative measure of their acidity or basicity.

1 × 10-7 moles H+ ions per litre of water is the concentration of hydrogen ions dissociating from pure water. The negative logarithm of this concentration is being used to estimate the pH.
