Mixtures. A mixture is a form of matter that is composed of two or more elements, two or more compounds, or of elements and compounds.

Properties of Solutions Postlab session

Recap What is a mixture? What are the two types of mixtures? What is the difference between homogeneous and heterogeneous mixtures? What are solutions? What are the two parts of a solution? What is a solute? A solvent? Are solutions always liquid?

Before we move forward… James loves eating fried chicken. Instead of ketchup, he prefer dipping this in vinegar. He prepared vinegar and added a pinch of salt. He mixed the vinegar so the salt will dissolve. Q1: Did James prepare a solution? Q2: What is the solute? Q3: What is the solvent? Q4. If James added ground pepper to his vinegar, will it still be a solution?

Activity 2 compare the evidence gathered with the predictions made; describe the properties of solutions based on observations.

Samples: sugar, salt, mongo seeds, powdered juice, cooking oil, vinegar Other materials: clear containers, improvised funnel, stirring rod, filter papers

Procedures Predict whether the samples will dissolve in water. Observe which of the liquid samples can be separated through filtration. Place 50 mL water into the clear containers. Filter the water with the sample. Add the samples to each of the containers and try to dissolve them by using the stirring rod. Observe which of the samples will dissolve in water.

Filtration used to separate the components of a mixture the liquid that passes through the filter paper is called the filtrate the material that will be left on the filter paper is called the residue

What is the evidence that the components of a mixture have been separated through filtration? Sample: Muddy water Sample: Salt in water

Properties of Solutions They have uniform appearance. They have a single phase. Their components cannot be separated through filtration.

How can the particles of solutions pass through the filter paper? The particles of solutions are very small that they can pass through the holes of the filter paper!

Why do solutions have uniform appearance? The very small particles of a solution are not seen by the naked eye, thus, we see only one phase!

Properties of solutions Summing it up… Solutions have only one phase thus, they have uniform appearance. The components of solutions cannot be separated through filtration because their particles are very small that they can pass through the holes of the filter paper. Properties of solutions

Going back… If James will filter the vinegar mixed with salt, will he be able to separate the salt from the vinegar? Why?

True or False? Solutions are homogeneous because they have two phases. The particles of a solution are bigger than the holes of a filter paper. The particles of solutions are not visible to the naked eye. Through filtration, the components of a solution can be separated. There is no residue left on the filter paper when solutions are filtered.

Next session… Review the procedures for Activity 3. Construct a flow chart for the procedures. Be sure to bring the materials needed! Bring ½ index card per group. Write the names of the members of the group.
