Candy Lab Part 1(intro)

Purpose:

 In this project-based unit, you will investigate the processes of dissolving and crystallizing at the particle level by making hardtack candy. You will then use your learning to
There are 3 main parts to this project. Each part will have a blog post. As you work, we will periodically discuss applicable content.

Terms:

Solvent is a liquid that can dissolve a solute, is a substance that dissolves in a solvent. Solubility is the most of a solute that may be dissolved in a solvent. During the candy making process, after the candy has gotten to the needed heat and is poured out on a pan, it starts to harden begins crystallization. And crystallization is the separation between a solid  and a liquid. Concentration is when you have a substance in a curtain amount of space. Finally molarity, which is the number of moles of solute divided by the number of liters of solution.

Solubility using a solubility curve:

Solubility is the most of a solute that may be dissolved into a solvent

Solubility's importance in candy making:

1. The solvent has to attract to the solute + and -

2. The solvent molecules take apart the solute

3. The solvent molecules are going to carry the ion particles around the solute

Physical and chemical process in making candy:
     Hard Tack Candy is made from a supersaturated solution of sugar water.  Sugar is dissolved in a big kettle of water until no more sugar dissolves at room temperature.  Then, the saturated solution is heated up.  The higher temperature allows for more sugar to be dissolved, so more sugar is put in.  As more and more sugar is put into the kettle, it dissolves, which makes the solution saturated at the new higher temperature.  Now, if the sugar is cooled down very slowly, and no more sugar is added, the sugar will stay dissolved.  As the temperature cools, the sugar dissolved at that higher temperature stays dissolved, and a supersaturated solution is made.
