Thread: Solution: Volatile or not?

G'ddy All

Achole is very volatile, so is ammonia solution. But some solution are not, such as diet oil.... But does anyone know what's the key reason that'll determine whether a solution will be volatile or not....?

No one knows?

Vapour pressure. Liquids such as acetone, petrol etc have high vapour pressures than liquids such as oils, which have very low vapour pressures.

A substance with a high vapour pressure will tend to evaporate more quickly. Technically ammonia solution is a different kind of equilibrium though, vapour pressures generally concern pure compounds.

then, what's so special with ammonia? give some detail?
