Acids and Bases Form 4

1. Chapter 7ACIDS AND BASES

3. pH less than 7

4. Corrosive

5. Conduct electricity

6. Acid can react with a) bases to produce salts and water b) metals to produce salts and hydrogen gas c) carbonates to produce salts , carbon dioxide gas and water

8. pH more than 7

9. Corrosive

10. Conduct electricity

11. Base can react with a)Acid to produce a salt and water b)Heated with ammonium salt to produce ammonia gas video

13. Carbonic acid- make carbonated drinks

15. Magnesium hydroxide – toothpaste

20. pH values of less than 7 indicates an acidic solution

21. pH values of more than 7 indicates an alkaline solution

24. higher concentration of hydrogen ionWhen acids meets base

25. pH is actually a measurement of the concentration of hydrogen, H+ in a solution The higher the concentration of the H+ ions, the lower the pH value, and more acidic the solution is The higher the concentration of the OH¯ ions, the higher the pH value and the more alkaline solution the solution is.
