Chapter 10 Acid-base titration
Across
- 5. a buret made of a glass spout specialized for acidic solutions, such as HCl, NHO3, oxidizing solution (KCrO4), and neutral solutions such as thiosulfate.(two words)
- 7. a laboratory tool used to measure and dispense small volumes of liquids, usually in the range of microliters or milliliters.
- 11. an acid that contains more than one ionizable proton(two words)
- 15. an indicator which has a pH range of 4.2 to 6.3(two words)
- 16. the plot of pH versus volume during a titration.(three words)
- 18. a buret used to dispense an alkaline liquid into a solution providing an excess of hydroxide.(two words)2
- 19. an acid that contains only one ionizable proton(two words)
- 20. a method of finding exactly how much of a substance there is in a solution by gradually adding measured amounts of another substance that reacts to it in a known way, for example by causing a colour change.
Down
- 1. an indicator which has a pH range of 3.1 to 4.4(two words)
- 2. a reagent solution of known exact concentration.(two words)
- 3. a term which may refer to the process of converting a molecule or atom into an ion by either gaining or losing an electron
- 4. an indicator that is colourless when it is mixed with an acid and pink or red when mixed with an alkali.
- 6. the point in a titration at which the indicator changes color.(two words)
- 8. a chemical reaction where a compound, usually a molecule or ion, is broken down into smaller particles through the addition of water.
- 9. a certain amount of the substance to be measured.
- 10. an indicator which has a pH range of 7.2 to 8.8
- 12. the point at which the reaction is complete.(two words)
- 13. a branch of chemistry that deals with the quantitative relationships between chemical substances during chemical reactions.
- 14. the substance used to indicate the titration process.
- 17. the difference between the calculated or theoretical endpoint of a titration and the actual endpoint obtained during the experimental procedure.(two words)
