Question

when distilled wateris kept in a sealed bottle for a long time wht it leave etching on surface of the glass

Answer 1

hey
here's your answer!!

Water is a remarkable solvent. It dissolves many substances, forming aqueous solutions.
Water has a high dielectric constant. As a result, it reduces the electrostatic force of attraction between positive and negative ions and dissolves even inorganic compounds, which are usually electrovalent. Not only solids, but also gases and other liquids dissolve in water. Hence, it is difficult to find absolutely pure water in nature.


Therefore, substances that are apparently insoluble in water actually dissolve in it. It is for this reason that, when distilled water is kept in a sealed bottle for a long time, it leaves etchings on the inside surface of the glass.

Hope it helps!!
