Molar Mass by Freezing Point Depression Lab Experiment, Boiling Point Elevation, Molality Lesson

Molar Mass by Freezing Point Depression Lab Experiment, Boiling Point Elevation, Molality Lesson

This 33-slide PowerPoint presentation introduces students to the concept of freezing point depression and boiling point elevation. It also includes a worksheet in which students can take notes and practice the skills learned during the lesson. • First, students will review what happens when a liquid freezes and when it boils. • Then, a discussion about how adding a nonvolatile solute would affect the freezing and boiling process. • Molality will be introduced followed by practice problems. • The freezing point depression and boiling point elevation formulas will be introduced with examples for students to work out. • Finally, a practical investigation to work out the molar mass of an unknown solute by using freezing point depression will be outlined with an example calculation. I hope you find this useful.

AQA Trilogy C1-4 Atoms, bonding and moles

AQA Trilogy C1-4 Atoms, bonding and moles

5-page revision resource - each topic is summarised in detail onto one page. A great way of using it is as a cheat sheet when doing exams or exam style questions - so students are learning as well as getting practise in! Included topics: Atomic structure, The periodic table, Structure and bonding and Chemical calculations. I wish I could give this for free but have made it as cheap as possible - save yourself hours of work!

Organic Chemistry Qualitative Analysis_Free

Organic Chemistry Qualitative Analysis_Free

The qualitative analysis of organic functional groups can be daunting for a lot of students because of the sheer number of observations and reagents they are required to memorize. The Organic Qualitative Analysis (OQA) is a high resolution MIND MAP tool that summarizes observable reactions e.g. addition of bromine to phenol results in a white ppt. OQA contains: 1) A completed MIND MAP - teachers can use this as a reference to plan their class. 2) Blank MIND MAP - students can print this and update it accordingly as they learn the qualitative analysis tests. It can also be used in class activity. Teachers can also use this as an assessment to test students’ understanding of the reaction. The paid version contains quite a lot more observable reactions that include functional groups such as ketone, aldehyde, methyl ketone and methyl alcohol.
