Chapter 3 Quiz Review Chemical Compounds

Label the following as characteristic of ionic (I) or covalent (C) compounds. High melting point Brittle Does not conduct electricity Dissolves easily in water Bonds are the the force of attraction between two oppositely charged particles Commonly formed between metal and nonmetal I C

Label the following as characteristic of acids (A), bases (B), or salts (S). 7. Low pH 8. Increase the hydrogen ion concentration in a solution 9. Formed from a neutralization reaction 10. Taste sour 11. Feel slippery 12. Found in soft drinks 13. Found in lye 7. A 8. A 9. S 10. A 11. B 12. A 13. B

H2SO4 + Ca(OH)2 CaSO4 + 2H2O Identify the acid. Identify the salt. Identify the base. What type of reaction is this? 14.H2SO4 15. CaSO4 16. Ca(OH)2 17.neutralization

Label the following as characteristic of ionic (I) or covalent (C) compounds. 18. Composed of elements who share electrons 19. Compounds are composed of molecules 20. Do NOT dissolve easily in water 21. Nonmetal – nonmetal combinations 22. Do not conduct electricity 23. Low melting points All COVALENT!

Label the following as characteristic of acids (A), bases (B), or salts (S). 24. KOH 25. CaO 26. HF 27. pH = 13 28. Used to neutralize acidic soil 29. Increased number of hydroxide ions in solution 30. Taste bitter 24. B 25. S 26. A 27. B 28. B 29. B 30. B

Don’t forget to also study… The different acids and bases and what they are used for/in What an indicator is The pH scale The two substances produced from a neutralization reaction What is produced when an acid and a metal react together What a buffer and a \salt is
