⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. The pH Scale An explanation of the pH scale as a measure of how acidic or alkaline a solution is, ranging from 0 to 14. Examples of substances at different pH values, including acidic, neutral, and alkaline solutions. 2. How to Measure pH Using chemical indicators, like universal indicator, which change colour depending on the pH. Using pH probes and meters to get a more accurate and precise numerical pH reading. 3. Defining Acids, Bases, and Alkalis An acid is a substance with a pH less than 7 that releases hydrogen ions in water. A base is a substance with a pH greater than 7. An alkali is a type of base that is soluble in water and releases hydroxide ions. 4. Neutralisation Reactions What happens when an acid and a base react together. The general products of a neutralisation reaction are a salt and water. The ionic equation for neutralisation. 5. Common Acids and Bases A list of common acids (hydrochloric, sulphuric, nitric) and bases (sodium hydroxide, calcium carbonate) to remember. ** CHAPTERS ** 0:00 Introduction 0:31 The pH Scale 1:26 How to Measure pH 2:47 Defining Acids and Bases 3:42 Neutralisation Reactions 4:33 Common Acids and Bases to Remember ** PLAYLISTS **    • KS3 Biology      • KS3 Chemistry      • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #GCSE #Chemistry #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE #KS3
