Solubility

​Solubility and Solubility Curves

By Jan Davis

Questions to think about:

• What happens to sugar when you stir it into tea?

• Why do some substances dissolve faster than others?

Solutions Review

• A solution is a homogeneous mixture (uniform composition).

• Opposite: heterogeneous mixture (like a salad or trail mix).

Types of Solutions

Before we get into it:

• Electrolytes: Dissociate into ions in water (NaCl). Conduct electricity.

• Non-electrolytes: Do not dissociate (sugar, glucose).

Note: While "separate" can often be used, "dissociate" has specific uses in contexts, such as a chemical reaction where a molecule breaks apart
