Worksheets, with answers, for calculating the pH of strong/weak acids, strong bases and Ka
A lesson (2 of 4) that leads students through how to interpret NMR, focussing on chemical shift and integration of peaks. Lesson includes:
Starter activity recapping branch chain isomers of pentane and identifying equivalent environments/protons
Summary of chemical shift, reference molecule and solvents used in NMR spectroscopy, and integration of peaks, with key points stated
Examples of identifying chemical shift and deducing integration peaks for molecules.
A lesson (1 of 4) that leads students through how NMR spectra are formed and interpreted, starting with identifying equivalent protons/environments in organic molecules, includes:
Starter activity recapping chain isomers of Heptane
Brief summary of how NMR functions, before working through examples of identifying equivalent environments
Plenary returning to starter activity of identifying the number of equivalent environments in chain isomers.
A lesson that leads students through pH curves are, how they differ depending on the strength of acid/base used, key points on curves, how they can be used to identify suitable indicators and associated calculations.
Lesson details as follows:
2 starter activities, depending on whether students have completed pH curves required practical.
Summary of pH curves, key points and links to indicators/calculations
Long answer summary question based on calculations around pH curves
Example questions and mark scheme to accompany lesson.
A lesson that leads students through what buffer solutions are, how they are formed and the two ways in which the pH of a buffer solution is formed. Lesson details as follows:
Starter activity so that students can identify weak and strong acids and the salts that they form.
Summary of the formation acidic and basic buffers
Worked examples of how to calculate the pH of acidic buffers, either from the mixing of a weak acid with it’s salt, or excess weak acid with a strong base.
Example questions and mark scheme to accompany lesson.
A summary of how to name organic molecules using the IUPAC naming system, suitable for AQA AS Chemistry and possibly other specifications. Contains the following files:
Summary of functional groups, prefixes and suffixes used and how and when they changes.
Guidance on numbering system and functional group priority.
Flow chart to aid the application of naming system.
Practice questions and answers.
Complete lesson demonstrating the effect of adding small amounts of acid and base to a buffer solution and how to calculate the resultant pH.
Starter to get students thinking about how the addition of acid/base affects the position of an equilibrium.
Worked examples of how to calculate the pH of a buffer solution before and after the addition of acid/base.
Exam questions, with mark scheme.
