The name of citric acid is 2 – Hydroxy propane 1, 2, 3 – tri carboxylic acid.


From the structure it is is clear that it has three acidic groups which can release 3 H+ ions per molecule when dissolved in water. So we might expected that it is a strong acid.
But actually this is not happening. When citric acid is dissolved in water it really do not want to release all the H+ ions. Hence, it is termed as weak acid.
