Acid and Bicarbonate of Soda - Results Tables 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 provided text outlines various scientific experiments and observations involving the classification of substances by their pH levels, the neutralisation of acids with alkalis, and the effects of changing variables on reaction times and temperatures. The first section details a series of substances, including cola, lemon juice, and vinegar, which are tested with pH paper to determine their pH levels and classify them as either acidic, alkaline, or neutral. This classification helps students understand the chemical nature of everyday substances.</p>

<p>Subsequent sections describe experiments that explore the interactions between acids and bicarbonate of soda (an alkali). One experiment measures the amount of bicarbonate of soda required to neutralise different vinegar/water mixtures. Another investigates the impact of bag size on the time it takes for a reaction-induced explosion when bicarbonate of soda is used. Additionally, the time to explosion is also measured by varying the amounts of bicarbonate of soda added. The final experiment examines how different ratios of bicarbonate of soda to citric acid affect the temperature change of the reaction, with the results recorded as starting and ending temperatures, as well as the temperature difference. These activities are designed to provide hands-on learning experiences about chemical reactions and their measurable effects.</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>
