*** 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.
