Across
- 3. acids composed of two atoms, a hydrogen element and a nonmetal element.
- 7. an acid that lost its hydrogen ion
- 10. a point in a titration that signifies the completion of the titration by a change in the colour or intensity of the solution.
- 13. acids that can lose several protons per molecule
- 14. a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.
- 17. a substance that donates a proton to another substance.
- 19. a solution that can resist changes in PTT when an acid or base is added to it; a buffer
- 20. compounds that, when dissolved in water, increase the concentration of hydrogen ions (H+) and are characterized by a sour taste and a pH below 7
Down
- 1. a proton acceptor
- 2. a hydrodium ions are the combination of a water molecule and a hydrogen ion, resulting in the formula, H 3 O +.
- 4. two substances that differ only by the presence of a proton
- 5. the substance that causes a solution to resist change
- 6. acids composed of two atoms, a hydrogen element and a nonmetal element
- 8. An acid that breaks down completely and gives off many ions, or protons
- 9. (of a compound, especially a metal oxide or hydroxide) able to react both as a base and as an acid.
- 11. the slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralization.
- 12. a chemical reaction in which acid and a base react with an equivalent quantity of each other.
- 15. a chemical reaction in which a chemical compound is broken down by reaction with water.
- 16. any process by which electrically neutral atoms or molecules are converted to electrically charged atoms or molecules (ions) through gaining or losing electrons .
- 18. low concentration of OH ions.
