- 3. a method or process of determining the concentration of a dissolved substance in terms of the smallest amount of reagent of known concentration required to bring about a given effect in reaction with a known volume of the test solution.
- 10. when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water.
- 14. acid) that contains within its molecular structure two hydrogen atoms per molecule capable of dissociating
- 15. such as phosphoric acid (H3PO4) and citric acid (C6H8O7), have three
- 16. an acid that dissociates incompletely, releasing only some of its hydrogen atoms into the solution.
- 17. is a solution containing a precisely known concentration of an element or a substance, a known weight of solute is dissolved to make a specific volume.
- 20. the ion H3O+, consisting of a protonated water molecule and present in all aqueous acids.
- 21. one that completely ionizes (dissociates) in a solution
Down
- 1. solutions resist pH changes. A buffer solution is typically made by mixing a weak acid and one of its salts OR mixing a weak base with one of its salts.
- 2. that has a higher concentration of hydroxide ions that hydrogen ions; a pH between 7 and 14.
- 4. an ionization reaction in pure water or an aqueous solution, in which a water molecule, H2O, deprotonates (loses the nucleus of one of its hydrogen atoms) to become a hydroxide ion, OH−.
- 5. or stoichiometric point, of a chemical reaction is the point at which chemically equivalent quantities of acid and base have been mixed.
- 6. the point in a titration at which a reaction is complete, often marked by a color change.
- 7. A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa
- 8. is a basic, ionic salt of an alkali metal or alkaline earth metal chemical element.
- 9. a chemical base that does not ionize fully in an aqueous solution.
- 11. (of a compound, especially a metal oxide or hydroxide) able to react both as a base and as an acid.
- 12. is something like sodium hydroxide or potassium hydroxide which is fully ionic.
- 13. hydrogen (H+) ions while bases produce hydroxide (OH-) ions in solution.
- 18. an acid such as H2SO4 (sula method or process of determining the concentration of a dissolved substance in terms of the smallest amount of reagent of known concentration required to bring about a given effect in reaction with a known volume of the test solution.
- 19. the measure of the acidity or alkalinity of a solution.
