whats the difference between making an aqueous solution of potassium chloride, KCL, and one of ammonia, NH3
On, is that KCl is an ionic solid, and you dissolve that solid in water.
NH3 is a gas(at normal temps), and one dissolves the gas in water. This gas is highly soluble, it turns out.
The last difference is the gas NH3 has a high vapor pressure when it is dissolved, that is, it escapes from the solution (just take a whiff of washing ammonia). KCl is not volatile in solution.
