- 2. dissociation constant: The ratio of the concentration of the conjugate acid times the concentration of the hydroxide ion to the concentration of the conjugate base.
- 3. solutions: Another name for basic solutions.
- 5. What is the process that reduces surface tension?
- 7. A substance that can act as both an acid and a base.
- 9. acid: A substance that can accept a pair of electrons to form a covalent bond.
- 13. point: The point at which the indicator changes color.
- 14. dissociation constant: The ratio of the concentration of the dissociated (or ionized) form of an acid to the concentration of the undissociated (nonionized) form.
- 16. Process of turning light into chemical energy, performed by plants.
- 17. acid: The particle formed when a base gains a hydrogen ion.
- 18. acids: Acids that contain one ionizable hydrogen.
- 19. Theory: Theory stating that acids are hydrogen-containing compounds that ionize to yield hydrogen ions (H+) in aqueous solution. He also said that bases are compounds that ionize to yield hydroxide ions (OH−) in aqueous solution.
- 20. Theory: proposition that an acid accepts a pair of electrons during a reaction, while a base donates a pair of electrons.
- 21. bases: Bases that react with water to form the hydroxide ion and the conjugate acid of the base.
- 22. constant for water: The product of the concentrations of the hydrogen ions and hydroxide ions in water.
- 25. base: The particle that remains when an acid has donated a hydrogen ion.
- 26. The process of adding a known amount of solution of known concentration to determine the concentration of another solution.
- 27. acids: Acids that contain two ionizable hydrogens.
- 28. solution: A in which [H+] is greater than [OH−].
Down
- 1. solution: Any aqueous solution in which [H+] and [OH−] are equal.
- 2. solution: A solution in which [H+] is less than [OH−].
- 4. reactions: Reactions in which an acid and a base react in an aqueous solution to produce a salt and water.
- 6. Negative logarithm of the hydrogen-ion concentration.
- 8. The reaction in which water molecules produce ions.
- 10. theory: The theory defining an acid as a hydrogen-ion donor, and a base as a hydrogen-ion acceptor.
