The solids are soluble in water if we increase the temperature solubility is also increase. This is also happening in case of NH4Cl.
Generally the solubility of NH4Cl is 38~39 % at room temperature.if we increase the temperature to 40℃, the solubility increase to 45% that is 450 g/L at 40℃. And if we increase the temperature again ,solubility increase. So, solubility pattern is perfect fit in case of NH4Cl.

1. Solubility in WATER Check solubility of four solutes in water (H2O). For each solute record how many teaspoons dissolved in 1/2 cup of water. NaCl: Start out with 4 small glasses (cups) and add 1/2 cup of water to each. Put 1/2 level teaspoon (tsp) of salt (NaCl) into the first cup and stir. If it dissolves within 1 minute; add another 1/2 tsp of salt and stir. Count the number of 1/2 tsps you are adding. Repeat until...
