What is a solution?

Back

A solution is a homogeneous mixture of two or more substances where one substance (solute) is dissolved in another (solvent). An example is salt water.

What is the universal solvent?

Back

Water is known as the universal solvent because it can dissolve more substances than any other liquid.

Front

What is solubility?

Back

Solubility refers to the amount of solute that can dissolve in a certain volume or mass of solvent at a specific temperature.

Front

What happens during dilution?

Back

During dilution, water is added to the volume of a solution, decreasing the concentration of the solute.

What is the solubility of NaCl at 10 degrees Celsius?

Back

At 10 degrees Celsius, the solubility of NaCl is 35.0 g per 100 g of water.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a mixture in which the components are not uniformly distributed, and different samples may have different compositions.

Front

What is a compound?

Back

A compound is a substance formed when two or more elements are chemically bonded together, such as water (H2O) or sodium chloride (NaCl).

Front

What is an element?

Back

An element is a pure substance that cannot be broken down into simpler substances by chemical means, such as oxygen (O) or gold (Au).

Front

What is the difference between solute and solvent?

Back

The solute is the substance that is dissolved in a solution, while the solvent is the substance that dissolves the solute.

Front

What is concentration?

Back

Concentration is the measure of the amount of solute present in a given volume of solution, often expressed in molarity (moles per liter).
