Answer:
weak acids indicate the relative equilibrium positions of the acids because there is very little reaction occur of weak acid with water.
Step-by-step explanation:
Weak acid dissociates very little when it react with water. The weak acid donate less proton as compared to strong acid so the solution of weak acid is in equilibrium state and no big change occurs during the reaction of weak acid with water. Weak acid react with water to a very small extent about less that 10 % so this the main reason of equilibrium of the solution.
