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 ...

This is called an equilibrium and is present in water and ... Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base reduces the ...

The concentration of hydrochloric acid can be increased by adding more hydrochloric acid. When this happens, the equilibrium position moves to the left, away from HCl(aq) in the equation.

Optimal pH homeostasis for cellular function is maintained by the acid-base balance through multiple buffering systems, such as the bicarbonate system, across the cell. Shifts in this equilibrium ...
