Question

can water cause molecules in a piece of chalk to break apart how can you say this

Answer 1

Chalk is a form of calcium carbonate & it remains insoluble in the water.

There is also an inter-molecular attraction between chalk ions & water molecules.

When the chalk is put wet inside the water, after a certain duration the state of chalk changes as it becomes liquid along with tiny powder particles.

This causes the breakage of water molecules in the chalk.
