Identify the solute and solvent in each of the following solutions: Salt water Kool- aid Solute? Solvent? 2. You have a big clump of sugar and you need it to dissolve as quickly as possible. What are 3 things that you learned that would increase the speed of dissolution (dissolving) and explain why? 3. Water is polar- draw a picture that demonstrates your understanding of this concept. 4. a. Explain why the polarity of water allows it to be such a good solvent. b. What types of bonded substances (ionic, polar covalent, non polar covalent) dissolve easily in water? 5. Napthalene, C10H8, is a non polar substance. Will this substance dissolve in water? Why or why not? 6. Both oil and water will dissolve in alcohol, what information can you formulate about the alcohol molecule in terms of polarity? 7. Complete the following chart: should we do this for acids and bases too? KBr C8H12 C6H12O6 HCl NaOH a) Bond type b) Draw image that shows on the MOLECULAR LEVEL how each of these would dissolve in water c) Electrolytes? Explain. 8. The solubility of KBr at 30°C is 70g/ 100g H2O. What mass of KBr can be dissolved in 50g of H 2O? 9. a) Generally, how does temperature affect the solubility of a solute? 10. Given 16 g of sulfur dissolved in 250 mL of water calculate: a) Molarity b) g/ L Are there any exceptions? (Show formulas & Show work) C) % comp d) ppm 11. Identify the following substance as an acid or a base based on the following characteristics: e) turns phenolphthalein pink a) reacts with Zn to form H2 gas bubbles b) pH= 9 f) turns ph/ litmus paper blue c) pH= 1 g) turns ph/ litmus paper red d) conducts electricity 12. Identify the compound as an acid or base & explain how you’ d know: a) H2SO4 + H2O H3O + + HSO4b) NH3 + H2O  OH- + NH4+ 13. Write how the following would dissociate in H2O & determine if they are an acid or base: a) HNO3  b) KOH  14. Draw a pH scale with the correct numbers and label where you’d find strong bases, weak bases, strong acids, weak acids, and neutral substances. 15. How does the concentration of H3O+ ions affect the number on the pH scale? What is H3O+ called? 16. How does a strong acid/ base differ from a weak acid/ base? 17. a) Write the products of the following reaction: KOH + HNO3  _______ + _________ b) What special type of double replacement reaction is this? c) Would this solution conduct electricity? How do you know? 18. Explain how to neutralize an acidic solution.
