Mixtures and Solutions

Front

What is a Homogeneous mixture?

Back

A mixture that has a uniform composition throughout, where the individual components are not distinguishable. Example: Tap Water.

Front

What is a Heterogeneous mixture?

Back

A mixture that has a non-uniform composition, where the different components can be seen and separated. Example: Beach Sand.

Front

What is a Colloid?

Back

A mixture where small particles are dispersed throughout but do not settle out. They can scatter light waves. Example: Milk.

Front

What is a Suspension?

Back

A mixture where larger particles are suspended in a liquid and can settle over time. Example: Mud water.

Front

What does 'different throughout' mean in terms of mixtures?

Back

It refers to a Heterogeneous mixture, where the composition varies from one part to another.

Front

What is the main characteristic of a solution?

Back

A homogeneous mixture where one substance (solute) is dissolved in another (solvent). Example: Saltwater.

Front

What is the Tyndall effect?

Back

The scattering of light by particles in a colloid or in very fine suspensions.

Front

What is the difference between a solution and a colloid?

Back

In a solution, the solute particles are at the molecular or ionic level and cannot be seen, while in a colloid, the particles are larger and can scatter light.

Front

What is an example of a colloid?

Back

Examples include milk, fog, and mayonnaise.

Front

What is the definition of a solute?

Back

The substance that is dissolved in a solution. Example: Salt in saltwater.
