We can define the solubility as the maximum amount of solute (which may be a solid, liquid or gas) that is dissolved in a solvent ( which may be a solid, liquid or gas).
The solubility of Ammonium chloride (NH₄Cl) at 50°C is 50 grams, because t<span>he </span>solubility of NH₄CL<span> is 50g /100g of water at </span>50°<span> C.</span>
