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