Study Notes
Acids and Bases Overview
- Acids donate protons (H⁺ ions), while bases accept protons (OH⁻ ions).
- Acids have a sour taste, are corrosive, and turn blue litmus paper red; bases have a bitter taste and turn red litmus paper blue.
Concentration
- Dilute solutions contain more water and less solute, while concentrated solutions have less water and more solute.
- Molar (M) is the unit of concentration; higher molarity means a more concentrated solution.
pH Scale
- The pH scale ranges from 0 to 14:
- Below 7 indicates acidity, with 7 being neutral, and above 7 indicating basicity.
- A decrease of one unit on the pH scale increases the concentration of hydrogen ions by a factor of 10.
Indicators
- pH indicators change color based on the acidity or alkalinity of a solution, with common examples including universal indicator, litmus paper, and red cabbage juice.
- Natural indicators like anthocyanin in red cabbage can be used to determine pH levels through color change.
Reactions
- When acids and bases react, they neutralize each other, producing water and salt.
- Acids react with metals to produce hydrogen gas and salt.
Environmental Impact
- Acid rain occurs due to atmospheric pollution, threatening ecosystems and corroding structures.
- Ocean acidification, caused by increased CO₂ levels, affects marine life, particularly organisms with calcium carbonate shells.
Household Examples
- Common household acids include acetic acid (vinegar), citric acid (lemons), and lactic acid (milk).
- Common household bases include sodium hydroxide (soap) and ammonia (cleaners).
Properties of Acids and Bases
- Acids are conductive and can corrode materials, while bases may feel soapy and are also conductive.
- Both acids and bases can cause severe burns upon contact with skin.
Understanding Dilution
- Mixing a stronger acid with water results in a diluted solution; more water indicates a lower concentration of acid.
- Comparing two beakers with different volumes of water added illustrates the dilution concept; more water means more dilution.
Chemical Comparison
- Strong acids produce many protons, while weak acids produce fewer.
- Both acids and bases conduct electricity and are neutralized in reactions with one another, forming water and salt.
