Chemistry

2. a proton acceptor
3. two substances that differ only by the presence of a proton
5. any process by which electrically neutral atoms or molecules are converted to electrically charged atoms or molecules (ions) through gaining or losing electrons .
6. 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.
9. acids composed of two atoms, a hydrogen element and a nonmetal element
11. a hydrodium ions are the combination of a water molecule and a hydrogen ion, resulting in the formula, H 3 O +.
12. low concentration of OH ions.
15. a chemical reaction in which acid and a base react with an equivalent quantity of each other.
17. a point in a titration that signifies the completion of the titration by a change in the colour or intensity of the solution.
18. acids that can lose several protons per molecule
19. an acid that lost its hydrogen ion
20. (of a compound, especially a metal oxide or hydroxide) able to react both as a base and as an acid.

1. a substance that donates a proton to another substance.
4. 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
7. a chemical reaction in which a chemical compound is broken down by reaction with water.
8. acids composed of two atoms, a hydrogen element and a nonmetal element.
10. the substance that causes a solution to resist change
13. a solution that can resist changes in PTT when an acid or base is added to it; a buffer
14. An acid that breaks down completely and gives off many ions, or protons
16. 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.
