Solutions, Solubility Curves, Water Polarity

Front

What is a solution?

Back

A homogeneous mixture of two or more substances where one substance (the solute) is dissolved in another (the solvent).

Front

What is an example of a solution?

Back

Salt Water.

Front

What type of charge do the hydrogen atoms in a water molecule have?

Back

Partial positive charge.

Front

What type of charge do the oxygen atoms in a water molecule have?

Back

Partial negative charge.

Front

What does a solubility curve show?

Back

The relationship between solubility of a substance and temperature.

Front

How does solubility change with temperature?

Back

Solubility generally increases as temperature increases.

Front

What is a homogeneous mixture?

Back

A mixture that has a uniform composition throughout, such as sugar dissolved in water.

Front

What is a heterogeneous mixture?

Back

A mixture that does not have a uniform composition, such as salad or concrete.

Front

How many covalent bonds does each water molecule have?

Back

Two.

Front

What is polarity in a molecule?

Back

Polarity refers to the distribution of electrical charge over the atoms joined by the bond.
