how much sodium benzoate can be added to 1 liter of water

14 6 Buffers

The buffer capacity is the amount of acid or base that can be added to a given volume of a buffer solution before the pH changes significantly usually by one unit Buffer capacity depends on the amounts of the weak acid and its conjugate base that are in a buffer mixture For example 1 L of a solution that is 1 0 M in acetic acid and 1 0 M in sodium acetate has a greater buffer capacity than

Buffer Calculations

Buffer solutions are used to calibrate pH meters because they resist changes in pH When you use a pH meter to measure pH you want to be sure that if the meter says pH = 7 00 the pH really is 7 00 So you use solutions of known pH and adjust the meter to display those values
