An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

Both members of the conjugate acid-base pair in a buffer solution need to be weak (weak acid and weak base). The weak acid component neutralizes added base and the weak basic component neutralizes ...

Why don’t the weak acid and weak base in the buffer solution react with and neutralize each other? Figure 5. Carbonic acid and its conjugate base, bicarbonate ion. Because both the acid and base in a ...
