Here is an attractive worksheet that walks chemistry learners through a review of aqueous solutions. There are matching, short answer, and multiple choice questions dealing with boiling and freezing points, precipitate, molality, net ionic equations, and osmotic pressure, all colligative properties. Assign it as homework to help prepare for a quiz.
In this physical equilibrium worksheet, students answer a variety of questions about changes in temperature of solutions and the effects on the solution. They calculate molality, boiling points, freezing points, and mole fractions in solutions.
A neat presentation and challenging content make this solutions worksheet an ideal homework assignment for your budding chemists. Short answer and problem solving questions get them to review molarity, products, and reactants.
For this chemistry worksheet, students examine the concept of thermodynamic equilibrium constants with intense detail. The application of the knowledge is practiced with problem solving.
Students explain how to make solutions with specific concentration. In this chemistry instructional activity, students differentiate acids and bases. They calculate molarity of solutions.
Students calculate the concentration of different solutions. In this chemistry lesson, students explain what a solution is. They explain ways to change the concentration of a solution.
In this solutions worksheet, learners determine how the amount of solute in a given amount of solvent effects the concentration of the solution. Students calculate the molarity of solutions. This worksheet has 7 fill in the blank, 3 short answer questions, and 6 problems to solve.
In this solutions worksheet, students calculate the concentration of solutions, or the mass and volume of given solutions. This worksheet has 10 problems to solve.
For this chemistry worksheet, students answer a sample exam with 13 problem solving questions on acids, bases and equilibrium reactions.
For this colligative properties worksheet, students solve 5 problems about boiling point elevation and freezing point depression. They rank aqueous solutions according to their boiling and freezing points.
Have you ever wondered why cities in cold climates put salt on the roads to help keep ice from forming? In this chemistry video, Sal explains why the introduction of salt molecules suppresses, or delays, the formation of ice crystals from liquid water. Additionally, he explains how the boiling point of water can be raised by adding certain substances to water. Very interesting!
Sal introduces students to mixtures and solutions. He starts out by explaining that homogenous mixtures, such as homogenized milk, are mixtures that are even and consistent throughout. He goes on to illustrate how the particle sizes in a variety of mixtures determine how homogenous that mixture will be. Examples include: paint, chocolate milk, jello, smoke, and fog.
In this chemistry Olympiad learning exercise, students solve sixty multiple choice questions on a variety of chemistry topics from finding molarity of solutions to calculating products of reactions. Students are given graphs, equations, reaction rates and other data to analyze.
Density comes to life as investigators place soda cans into containers of various liquids to find if they sink or float. They layer different density liquids, compare densities of different gases, and more. A total of six different density exercises help earth science learners grasp how differing density drives the motion of Earth's magma, oceans, and atmosphere. You will find this unit complete with several assessment or homework assignments.
Immerse your chemistry class in solutions! They melt and compare the mixtures that make up margarine, separate black ink into its component colors, distill ocean saltwater, and practice chromatography with plant pigments. There are eight activities in all, along with 11 assessment questions. This resource is a valuable addition to your chemistry curriculum collection.
This sequence of increasingly difficult questions about concentration asks learners to calculate the mass or amount of a substance in a solution. The questions then tests understanding by asking for an evaluation of boiling points, vapor pressure, osmotic pressure, and freezing points of certain solutions. An excellent test of comprehension, as questions are phrased in different ways, and calculations are needed, but not presented as such.
Students identify the boiling point elevation.  In this investigative lesson students differentiate between different properties in a solution. 
Eight multi-step chemistry problems, including analyzing a titration, writing equations, predicting products and limiting reagents, calculating concentrations of ions, and using stoichiometry to solve for unknowns in reactions make up this outstanding exam.
In this chemistry olympiad lab learning exercise, chemists are required to design two experiments. In one, they design an experiment to identify seven solutions given to them in pipettes. In the other, they design an experiment to determine the amount of gas the type of metal produced when two given substances are mixed in a balloon.
The 2009 version of the first part of a national chemistry competition is posted for your use with olympiad hopefuls. Test takers deal with 60 multiple choice questions covering an entire year of chemistry curriculum. Use this to practice for the competition or to prepare for a final exam on behavior of gases, properties of metals, chemical reacitons, pH and titration curves, ionizaton energy, molecular geometry, and more!
