Multiple Choice

A 100ml water is mixed with 20ml ethyl alcohol to form a solution. Which is the solute in the solution?

• water

• alcohol

• minerals in the water

• chemicals in the alcohol

​Classification of Matter

​

​A heterogeneous mixture is when the composition is not uniform throughout the mixture

Colloid vs. Suspension

both are made by two or more substances mixed together

Suspensions are a heterogeneous mixture

• the particles in suspension are larger than in colloids

• particles settle down by gravity.

​Colloids can exist as both homogeneous and heterogeneous

​A homogeneous mixture is also called solution. A solution is composed of a solvent and a solute

Solute dissolves into solvent to form solutions.

Solvent dissolved the solute, must be greater or greatest in amount in a solution

​solution-made of two or more substances
