Study Notes
General Concepts of Acids and Bases
- Salt is the ionic compound formed from the reaction of an acid with a base.
- Neutralization refers to the chemical reaction between an acid and a base, typically resulting in water and a salt.
pH and Ion Concentration
- The pH scale measures the concentration of hydrogen ions (H+) in a solution, indicating its acidity or basicity.
- Acids, characterized by a pH ranging from 0 to 6, increase hydrogen ion concentration in water.
- Bases, with a pH ranging from 8 to 14, produce hydroxide ions (OH-) in water.
Taste and Indicators
- Acids in food commonly have a sour taste, while bases often taste bitter.
- Litmus paper is used as an indicator, turning red in acidic solutions and blue in basic solutions.
Reactions with Metals and Carbonates
- Acids can cause corrosion when they react with metals such as magnesium, zinc, and iron.
- Bases do not react with these metals, remaining inert.
- When acids interact with carbonates, they produce carbon dioxide (CO2), while bases do not exhibit a reaction with carbonates.
Indicators
- An indicator is a compound that changes color when it comes into contact with an acid or a base, helping to identify the solution's pH.
