pH & Neutralisation Explained | GCSE Chemistry Core Practical 2 (Acids & Alkalis)

How do you turn an acid into something neutral — and how do you prove it?In this episode of GCSE Science Simplified, we break down GCSE Chemistry Core Practical 2, investigating pH changes during neutralisation using hydrochloric acid and calcium hydroxide (or calcium oxide).You’ll learn:What pH actually measures (hydrogen ions vs hydroxide ions)How neutralisation works: H⁺ + OH⁻ → H₂OHow to track pH changes using universal indicator and pH probesWhat happens when a solution moves from acidic → neutral → alkalineHow to identify the exact point of neutralisation (pH 7)Common practical errors — and how to improve your methodThis episode is perfect for:GCSE Chemistry revision (Edexcel, AQA, OCR)Understanding acids, alkalis, and pH scalePreparing for required practical exam questions Clear explanations. Real experimental thinking. GCSE-ready understanding.Listen now to master pH, neutralisation, and core practical skills — and boost your exam confidence.
