What we have learnt
- Acids are sour, turn blue litmus paper red, and release hydrogen ions in solution.
- Bases are bitter, slippery, turn red litmus paper blue, and release hydroxide ions in solution.
- The pH scale quantitatively measures acidity or alkalinity, ranging from 0 (acidic) to 14 (alkaline), with 7 being neutral.
Key Concepts
- -- Acids
- Substances that release hydrogen ions (H+) in solution and are characterized by their sour taste and ability to turn blue litmus paper red.
- -- Bases
- Substances that release hydroxide ions (OH-) in solution, often having a bitter taste and slippery feel, and turning red litmus paper blue.
- -- pH Scale
- A logarithmic scale ranging from 0 to 14 that indicates the acidity or alkalinity of a solution based on the concentration of hydrogen ions.
- -- Neutralization
- A chemical reaction between an acid and a base that produces a salt and water, effectively canceling out the properties of both reactants.
- -- Indicators
- Chemical compounds that change color in response to pH changes, used to determine the acidity or basicity of a solution.
