Study Notes
Acids
- Acids are solutions with a pH of 5 or lower, indicating an increase in hydrogen ions.
- A solution that feels slippery is associated with bases, not acids.
- Gastric juice is more acidic than acid rain and rainwater, playing a critical role in digestion.
Bases
- Bases have a slippery feel, which is a characteristic descriptor.
- A solution with an excess of hydroxide ions is classified as a base.
- Antacids are examples of slightly basic substances that neutralize stomach acid.
Indicators and Tests
- Phenolphthalein is a pH indicator that turns pink in basic solutions, indicating the presence of hydroxide ions.
- A positive test for acidity occurs when blue litmus paper turns red upon contact with an acidic solution.
- The presence of bubbles when a solution is placed on a metal typically indicates an acidic reaction.
Neutralization Reaction
- Neutralization is the chemical reaction that occurs when an acid and a base combine to produce salt and water, helping to balance pH levels and overly acidic or basic conditions.
