Acid and Bicarbonate of Soda - Presentation is part of the lesson Acid and Bicarbonate of Soda    Students will learn about acid and bicarbonate of soda as part of their learning about properties and changes of materials, as specified by the national curriculum in England: science programmes of study.

<p>The educational presentation on 'Acid and Bicarbonate of Soda' delves into the fascinating world of chemical reactions, specifically focusing on the properties and changes of materials. Students are posed with thought-provoking questions designed to assess their understanding of how to identify signs of a chemical reaction, the products that result from such reactions, and the classification of substances based on their pH levels. The session begins with a practical scenario where students Ramani and Poppy, under the guidance of their biology teacher Mr Mathers, apply their knowledge of pH to test the acidity or alkalinity of water samples using pH paper, which changes colour according to the pH scale. This interactive approach to learning helps students grasp the concept of pH and its implications in real-world situations.</p>

<p>As the lesson progresses, students are encouraged to classify substances as acids, alkalis, or neutral based on their pH values, with the pH scale ranging from 1 to 14. They learn that substances with a pH less than 7 are acidic, a pH of 7 is neutral, and a pH greater than 7 is alkaline. The presentation further explores the neutralisation process, where vinegar (an acid) and bicarbonate of soda (an alkali) are combined, resulting in a neutralisation reaction that produces carbon dioxide gas and has practical applications such as treating heartburn. Additional experiments, like the 'Exploding Bag', demonstrate the vigorous reaction between vinegar and bicarbonate of soda, while another activity investigates the endothermic reaction when bicarbonate of soda reacts with a solid acid, cooling the surroundings. These hands-on activities not only solidify students' understanding of chemical reactions but also demonstrate how to identify the production of gases and the effects of varying the ratios of reactants.</p>

<p>The main focus of this lesson is to explain that some changes result in the formation of new materials, which is not usually reversible. Students will learn about chemical reactions and the signs that indicate a reaction has occurred, such as the formation of gas, heat, or light. They will also learn to identify the products of chemical reactions. The class will also classify substances as acids, alkalis, or neutral based on their pH level, which is a measure of the ability of a substance to produce hydrogen in solution. The pH scale ranges from 1-14, with values below 7 being acidic, values above 7 being alkaline, and 7 being neutral. </p> <p>This lesson is aligned with the previous learning in Year 1 to identify and name everyday materials and in Year 2 to find out how solid objects' shapes can be changed. The activity will involve using pH paper and a variety of substances such as cola, lemon juice, bicarbonate of soda, vinegar, and more to classify the substances as acid, alkali, or neutral. Students will work in groups of four and follow the steps of tearing off some of the pH paper and dipping it into the sample, observing the color change, and making a judgement of the pH level. </p> <p>In the second activity, students will learn about neutralizing acids. They will measure out different amounts of vinegar and bicarbonate of soda, stir the mixture, and test the pH level until the paper turns green. They will repeat the process with different ratios of vinegar and bicarbonate of soda to understand the effect of adding more or less of either substance on the pH level. </p> <h2>Cross-Curricular Links</h2> <ul> <li>DT: Research the role of acids in etching</li> <li>Maths: Produce graphs of experimental results</li> <li>History: Write an essay on the role of acids in the first battery made</li> </ul> <h2>Important Lesson Guidance</h2> <p>Before the lesson, the teacher will need to obtain some cola, bicarbonate of soda, and lemon juice. For the pH classification activity, the teacher has free reign on the substances tested, as long as they are safe for students to handle. The solid samples will need to be mixed with a small amount of water for testing. In the neutralizing acids activity, the equipment required includes clear plastic cups, vinegar, bicarbonate of soda, pH paper, teaspoons, and a measuring cylinder. The students will work in groups of two. </p> <h2>Influential Scientists</h2> <p>Soren Sorensen, Jons Berzelius, Humphrey Davey. </p> <h2>Keywords</h2> <p>Irreversible, Acid, Alkali, pH scale, Neutral, Carbon Dioxide, Neutralization. </p>
