Question

"Tents are coated with a thin layer of aluminum hydroxide" Why?

Answer 1

As we know, Tents clothes are made of tightly woven fabric so that water with its high surface tension cannot easily penetrate . But falling raindrops can overcome the surface tension and wet the fabric which will then start seeping water to its other side.

We know, Aluminium hydroxide is insoluble in water and water repellent. Thus, it drains off the raindrops before they can wet the fabric. Hence, tents are coated with a thin layer of aluminium hydroxide

Answer 2

Tents are coated with a thin layer of aluminum hydroxide because aluminium hydroxide is insoluble in water repellent.

Thus, it drains off the raindrops before they can wet the fabric.
