Study Notes
Acids and Bases Overview
- Acids are substances with a pH between 0 and 6, indicating higher hydrogen ion concentration.
- Bases are substances with a pH from 8 to 14, indicating higher hydroxide ion concentration.
- A neutral solution has a pH of 7.
Ion Formation in Water
- Acids dissociate in water to produce hydrogen ions (H+).
- Bases dissociate in water to produce hydroxide ions (OH-).
Strength of Acids and Bases
- Strong acids completely dissociate into ions in a solution, while weak acids partly dissociate.
- Strong bases fully dissociate into ions, whereas weak bases only partially dissociate.
Hydrogen Ion Concentration
- A solution with a pH of 3 has a greater concentration of hydrogen ions compared to a solution with a pH of 7.
Neutralization and Products
- The reaction between an acid and a base results in the formation of water and salt.
Chemical Reactions and Indicators
- Acid rain results from atmospheric pollutants and is harmful to the environment.
- Foods and taste perception:
- Acids typically have a sour taste.
- Bases usually have a bitter taste.
- In litmus tests:
- Acids turn litmus paper red.
- Bases turn litmus paper blue.
Reactivity with Carbonates and Metals
- Acids react with carbonates to produce carbon dioxide gas.
- Bases generally do not react with carbonates.
- Acids react with metals (e.g., magnesium, zinc, iron) producing hydrogen gas and are corrosive.
- Bases do not generally react with these metals.
Corrosivity and Classification
- Corrosive substances can wear away materials over time.
- Substances that react with metals to generate hydrogen gas are classified as acids.
- Indicators are substances that change color in the presence of acids or bases.
Bases vs. Acids
- Bases are considered "opposites" of acids due to contrasting tastes, effects on litmus paper, and reactivity with metals and carbonates.
