Question

A weak acid ha has a ka 1.00*10 raise to -5 . If 0.100 mol of acid is dissolved in 1 litre of water the % of acid dissociateed at equilibrium

Answer 1

Answer:

Buffers are solutions that can resist changes of pH, when small amounts of acid of alkali are added to them

There are 2 types of buffer:

- Acidic Buffers

- Basic Buffers

Both work via an equilibrium reaction which moves in the direction to remove either: additional H⁺ ions or OH⁻ ions if they are added
