Phosphate buffer ph 2.0
WebIt is defined as the ratio of acid or base added (in gram-equivalents per liter) to the change in pH (in pH units). The capacity of a buffered solution is adjusted to the conditions of use, usually by adjustment of the concentrations of buffer substances. Buffers are used to establish and maintain an ion activity within narrow limits. WebIf you begin with 0.2M of either one and then adjust the pH with acid or base, say you need 10-20 ml of acid or base to adjust the pH correctly for 100ml solution, now your phosphate...
