Study Notes
Acids and Bases Concepts
- pH Scale: Measures the acidity or alkalinity of a solution, with a range typically from 0 to 14.
- Hydronium Ion (H₃O⁺): The ion formed when an acid donates a proton to water; a key species in acid-base chemistry.
- Salt Formation: Result of the neutralization reaction between an acid and a base.
- Titration: A quantitative method to determine the concentration of an acid or base in a solution through controlled addition of a titrant.
Types of Acids and Bases
- Binary Acids: Acids composed of two elements, usually hydrogen and a non-metal (e.g., HCl).
- Buffer Solutions: Solutions that minimize changes in pH upon the addition of small amounts of acids or bases, essential for maintaining stable environments.
- Arrhenius Acid: Substances that release hydronium ions when dissolved in water.
- Ionization Process: The dissociation of an acid in water, leading to the formation of hydronium ions.
Chemical Reactions and Definitions
- Indicator: A substance that changes color at the endpoint of a titration, signaling the completion of the reaction.
- Neutralization Reaction: The process where an acid reacts with a base to form water and a salt, effectively reducing the pH to neutral.
Brønsted-Lowry Theory
- Proton Donor: An acid according to Brønsted-Lowry theory, characterized by its ability to donate protons (H⁺ ions).
- Proton Acceptor: A base in the Brønsted-Lowry system, which gains protons during reaction.
- Amphoteric Substances: Compounds that can function as either acids or bases depending on the context of the reaction.
Chemical Equilibrium Concepts
- Conjugate Pairs: Acid-base pairs that differ by one proton, illustrating the reversible nature of acid-base reactions.
- Titration Endpoint: Achieved when equivalent moles of H⁺ and OH⁻ have completely reacted, indicating that neutralization is complete.
Acid Strength
- Weak Acids: Acids with small equilibrium constants (K₀), illustrating limited dissociation in water.
- Hydrolysis Reaction: Interaction of an ion with water to produce H⁺ and OH⁻ ions, significant in various chemical and biological processes.
