<p>This includes two PowerPoint presentations, outlining the formation of polyesters, polyamides and addition polymers. Colour-coding of functional groups helps students to visualise the changes that take place. Also includes practice exam questions with mark scheme, as well as an end of chapter test and mark scheme.</p>

<p>The PowerPoint covers the theory of both acidic buffer solutions and alkaline buffer solutions, and multiple worked examples of exam style questions involving calculations associated with buffer solutions.</p>

<p>This PowerPoint includes: An introduction to the topic of acids and bases, calculating the pH of a strong acid from its concentration and vice versa, and explanation of the ionic product of water, Kw. The resource includes exam-style questions with worked examples.</p>

<p>This PowerPoint includes multiple worked examples of exam-style questions covering all calculations associated with the acids and bases chapter. Also includes examples of exam-style questions relating to the acid-base titration required practical.</p>

<p>This is a series of nine PowerPoint presentations that cover all of the content from the Acids and Bases chapter of the AQA A2 Chemistry syllabus. In addition to clear explanations of the core concepts, these presentations also include many exam-style questions with detailed worked examples and model answers.<br /> The presentations cover the following topics: Introduction to acids and bases, calculations involving strong acids, the ionic product of water (Kw), calculations involving strong bases, calculations involving diprotic and dibasic solutions, calculations involving weak acids, indicators, buffer solutions and associated calculations, practice exam questions linking all topics covered.</p>

<p>This includes a PowerPoint covering the interpretation of infrared spectra, and assigning specific peaks to different functional groups. Also include practice questions and past exam questions with mark schemes.</p>

<p>This PowerPoint recaps the pH curves associated with different acid-base titrations, and then covers the theory of indictators and the mechanism that cause colour change. Also covers the pH range of different indicators and how this relates to the equivalence point of a titration.</p>

<p>This PowerPoint covers the theory of strong bases, how to calculate the pH of a strong base and vice versa. The PowerPoint includes exam-style questions and worked examples, as well as information from examiner’s reports, with a strong emphasis of the correct use of key terms.</p>

<p>The PowerPoint covers the topic of weak acids and the equilibrium constant, Ka as well as several worked examples of exam style questions related to calculating the pH of a weak acid. Also covers the concept of pKa and an introduction to acid-base titrations.</p>

<p>This PowerPoint includes multiple worked examples of exam-style questions. This includes calculating the pH of a strong diprotic acid from its concentration and vice versa, and calculating the pH of a strong dibasic base from its concentration (using Kw) and vice versa. The lesson also includes examples of the calculations involved with making solutions (using the formula C1xV1 = C2xV2).</p>
