A2 Chem: acids, bases and pH.

(0)
This resource is a lesson created for A2 Chemistry OCR syllabus which covers Bronsted - Lowry acids and bases, conjugate acid-base pairs, mono, di and tribasic acids, neutralisation reactions with acid: carbonates, metal oxides and alkalis. Includes theory, is interactive and has questions and answers. It has step-by-step guides to calculations and refers to OCR Chemistry textbook (states page numbers of summary questions to complete at end of teaching a mini-topic). Watch me teach the basics of part this topic at ‘PhysChem with Liz’ on YouTube: weak acids (calculations): strong acids (calculations): https://youtu.be/NTEa1sBThRg

Calculations (step by step) for unit 19 learning outcome A - Analyte determination

Attached are step-by-step calculations with equations, ratios, units etc which were created for the new unit 19 in the level 3 applied science course (new from 2016). The calculations are for the determination of bicarbonate in bottled water, the amount of copper in brass and the amount of iron in iron tablets. There are 3 stages to the bottled water practical, the end answer states the concentration of bicarbonate in water (tap water was used to save money!) in moles per decimetre cubed.

This bundle includes an assignment brief (created by me), lesson on thermodynamics and feasbility (can be easily adapted for what level/content you would like to teach) and answers to the last 4 assignment questions. This was created for a level 4 course where I taught chemistry to biology apprentices (ages 18+). The title of the unit was ‘chemistry for applied biologists’ and this is one of 4 assignments set in that unit. It could also be used for A2 Chemistry as there are some worked examples and practice questions on Gibbs free energy and 2 redox practicals which include half equations and observations.

Risk assessments: The why and how

(0)
This contains a (relatively!) exciting PowerPoint lesson around what can be a boring and tedious topic - risk assessments and safety. It includes case studies and scandal, what can happen when we are not aware of the risks involved. This is suitable for any science course at any level I have also included a very short lesson on authority and accountability i.e. academic fraud, this is also suitable for any course at any level. It was initially created for the old BTEC level 3 applied science, but is not specific to this :)
