Across
- 2. a chemical substance that neutralizes alkalis, dissolves some metals, and turns litmus red; typically, a corrosive or sour-tasting liquid of this kind.
- 3. model that says a base accepts electron pairs
- 5. a chemical reaction in which acid and a base react quantitatively with each other.
- 6. a chemical compound formed when an acid donates a proton (H) to a base
- 7. a chemical compound consisting of an ionic assembly of positively charged cations and negatively charged anions
- 8. acids/bases that are completely or nearly 100% ionized in their solutions
- 12. theory that describes bases as OH- ion donators
- 13. theory that describes bases as H+ ion acceptors
- 16. able to react both as a base and as an acid.
- 19. the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons
- 22. any chemical solution which has a precisely known concentration.
- 23. acids/bases that don't completely dissociate in solution
Down
- 1. where the moles of acid and the moles of base would neutralize each other according to the chemical reaction.
- 4. a halochromic chemical compound added in small amounts to a solution so the pH of the solution can be determined visually or spectroscopically by changes in absorption and/or emission properties.
- 9. process of chemical analysis in which the quantity of some constituent of a sample is determined by adding to the measured sample an exactly known quantity of another substance with which the desired constituent reacts in a definite, known proportion
- 10. the BASE dissociation constant
- 11. a measure of hydroxide ion (OH-) concentration. It is used to express the alkalinity of a solution.
- 14. the common name for the aqueous cation H₃O⁺, the type of oxonium ion produced by protonation of water. It is often viewed as the positive ion present when an Arrhenius acid is dissolved in water, as Arrhenius acid molecules in solution give up a proton to the surrounding water molecules.
- 15. a diatomic anion with chemical formula OH⁻. It consists of an oxygen and hydrogen atom held together by a single covalent bond, and carries a negative electric charge. It is an important but usually minor constituent of water. It functions as a base, a ligand, a nucleophile, and a catalyst.
- 16. the compound obtained by removing the elements of water from a particular acid.
- 17. "potential of hydrogen", is a scale used to specify the acidity or basicity of an aqueous solution.
- 18. a solution that can resist pH change upon the addition of an acidic or basic components.
- 20. a chemical species that donates electrons, accepts protons, or releases hydroxide (OH-) ions in aqueous solution.
- 21. the ACID dissociation constant
