In this molal boiling point worksheet, learners complete a virtual lab experiment to determine the molal boiling point constant of water. Students use a calorimeter to measure the boiling point of water at the current atmospheric pressure and then they measure the boiling point of a salt solution. Learners use their data to find the molal boiling point constant for water.
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!
Explore the properties of solutions with a lab activity. Chemistry fans determine the boiling point of water, add salt to create a solution, and then repeat the process four more times. They design their own data table and then graph the results to show how the addition of salt affects the boiling point temperature. This is suitable for junior high physical science classes as well as beginning high school chemists. Notes for setting up the lab are also included.
Students predict changes in freezing and boiling points of water, given type and quantity of solute added. They solve word problems for changes to boiling points and freezing points of solutions based upon data supplied. They describe and discuss the evolution of glass making through the ages.
This handout details different concepts and calculations with three example problems. This well-thought-out worksheet even includes a chart of boiling point elevation and freezing point depression constants. Use this resource as a teaching tool and practice for your chemistry class.
Here is an attractive learning exercise 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.
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.
Advanced chemistry kids experiment with the freezing and boiling points of various aqueous solutions. They also prepare a presentation of the kinetics of solution formation and structure of the matter involved. This resource provides you, as the teacher, with detailed laboratory instructions as well as extensive background information. You will need to design laboratory sheets so that learners will have instructions on-hand.
Practically everything you ever wanted to teach about acids, bases, and solutions can be found in these 158 slides! This A+ PowerPoint examines in-depth the components of a solution and the step-by-step process of dissolving. It examines the components of solubility, ionization, and dissociation. More information is available than can be summarized here. An added bonus is that scattered throughout the presentation are questions for evaluating viewer comprehension. This is a resource you will want to get your hands on!
In this colligative properties worksheet, students are given two sample problems showing how to find the freezing point depression and the boiling point elevation of solutions. Students solve two multi-part problems finding the boiling point elevation and the freezing point depression of the given substances.
In this solutions worksheet, learners review the factors that determine whether a substance will dissolve in another and what influences the rate of dissolution. Students review molarity and molality. This worksheet has seventeen short answer questions and nineteen problems to solve.
