For liquids and solids, solubility’s generally increase with increasing temperature, as is the case with sugar in tea. To fully characterize the solubility properties of a salt of interest, the chemist must gather data from %PDF-1.5
Example: Na 2 CO 3, K 2 SO 4, NH 4 Cl salts are all soluble in water. 1 0 obj
This will be done by combining different amounts of the salt in similar amounts of water and heating the solutions until all of the solute completely dissolves. <>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>>
If all of the salt (solute) disappears then the solute is said to have dissolved in the solvent and a solution is produce. Water solubility is an important physical property in chemistry, and is often expressed as the mass of solute that dissolves in …
