What makes a balloon explode when it meets citric acid?

The reason why the balloon will explode when it encounters citric acid is that citric acid contains aromatic hydrocarbons, which are highly soluble, which will make the latex layer of the balloon thin or burst. Moreover, the thinner the latex layer of the balloon, the less pressure it can withstand. When the tension of the balloon is uneven, it will explode.

Citric acid at room temperature, citric acid is a white crystalline powder, odorless, very acidic taste, density 1.542g/cm3, melting point 153-159℃, above 175℃ decomposition releases water and carbon dioxide.

Citric acid is easily soluble in water, with a solubility of 59% at 20 ° C and a pH of 2.1 in its 2% aqueous solution.

The crystalline form of citric acid is different with different crystallization conditions, and it has slight weathering in dry air.
