Chemistry Music Video 24: For Those About To Dissolve We Solute You

This song explains "like dissolves like", solubility, saturated, unsaturated and supersaturated solutions, how to use a solubility curve graph and how the freezing and boiling point of a solution is dependent on concentration.

Lyrics: A salt dissolved in water in a beaker today The ions broke apart in the usual way The molecules of water kept the ions apart A salt solution formed, but thats only the start! Homogenous! The same throughout! Homogenous! The same throughout! Solvents that are polar can dissolve solutes That are polar or ionic, that is really cute Water and nonpolar solutes just wont mix But a nonpolar solvent like benzene can fix! Like dissolves like! Polar and polar! Like dissolves like! Nonpolar and nonpolar! When all the solvent molecules used up And are stuck to the solute ions in your cup Solutions saturated, it is full for sure Solubilitys been reached for that temperature Saturation! On the line! Saturation! On the line! If theres still some water molecules unstuck Then more solute can dissolve, HEY! Youre in luck! Solution is unsaturated, cant you see You havent yet reached the solubility Unsaturated! Put more in! Unsaturated! Put more in! If you put more solute in than can be dissolved Then a supersaturation situations evolved! The excess falls out as a precipitate Or the solute is unstable, sodium acetate! Supersaturation! Precipitate! Supersaturation! Precipitate! A salt <b>...</b>
