Across 4. The kind of scale for pH 5. Prevents the pH of a solution from changing much when either small amounts of an acid or base are added to it 7. A solution where the hydrogen ion concentration is greater than the hydroxide ion concentration 10. Ka can be calculated for these solutions 11. The salt formed when hydrochloric acid is combined with potassium hydroxide. 12. The economic health of a country can be determined by how much of this it produces 14. Vitamin C 17. Produces OH- in solution 19. One of the products of combining an acid and a base 21. Produces H+ in solution 22. pH when hydrogen ion concentration is 1 x 10 -8 23. Bases can be used to dissolve this 24. Stomach acid 26. Accepts hydrogen ions 27. The feel of bases 28. Kb can be calculated for these solutions 31. A solution where the hydroxide ion concentration is greater than the hydrogen ion concentration 34. The sum of the pH and pOH 36. As the pH of a solution increases, the solution becomes more __________________ 37. Donates hydrogen ions 38. The negative log of the hydrogen ion concentration 39. The negative log of the hydroxide ion concentration 40. pH equals 7

Down 1. The taste of acids 2. The acid in vinegar 3. Electron pair acceptor 6. Used in eyewash 8. What is left after a base accepts a hydrogen ion 9. The acid in car batteries 13. What is left after an acid donates its hydrogen ion 15. Acids and bases can conduct electricity, so are called this 16. One of the products of combining an acid and a base 18. As the pH of a solution decreases, the solution becomes more _________________ 20. Electron pair donor 25. pH above 7 29. The weak base NH3 30. pH below 7 32. This product can be made using sodium hydroxide and fat 33. The taste of bases 35. The salt formed when nitric acid is combined with potassium hydroxide.
