1 Warm up (Jan 5) Give 6 different types of solutions, with an example of each. 1
2 Warm Up (Jan 6) 1. Write the reaction showing the dissolving of the following solids (be sure to note whether they are covalent or ionic!). Include states. a. Ca 3 (PO 4 ) 2(S) b. CO 2(g) 2. State whether each of the following is an endothermic or exothermic process, and whether it would feel hot or cold: a. Breaking bonds between solute molecules b. Breaking bonds between solvent molecules c. Forming new bonds between solvent molecules 2
3 1. Define the following terms: a. Electronegativity Warm Up (Jan 7) b. Polarity 2. Explain how polar bonds are formed in terms of electronegativity. 3
4 Warm Up (Jan 11) 1. Explain how a hot pack works in terms of solution formation. Use the energy changes that occur during the breaking and forming of bonds to explain the process. Breaking bonds between solute is endothermic Breaking bonds between solvent is endothermic. Making bonds between solute and solvent is exothermic If more energy is released in making bonds than is used in breaking bonds, the solution will feel hot. 4
5 Warm Up (Jan 12) 1. Give 2 ways you can make a solid dissolve faster. 2. Give 2 ways you can make a solid dissolve more. 3. Write the dissociation reaction for magnesium chloride. 4. What is an electrolyte? 5
6 Warm Up (Jan 13) 1. Write the reaction showing the dissolving of the following: a) AlCl 3 (s) b) PCl 3 (s) 2. Use your solubility table to answer the following questions: a) 100 grams of water are saturated with sodium nitrate at 40 o C. If this solution is heated to 70 o C, how much more can be dissolved? b) How many grams of ammonium chloride will dissolve in 65g of water at 70ºC? c) What is the solubility of sodium chloride in 100 grams of water at 50 o C? 6
7 Warm Up (Jan 14) Use your solubility table to answer the following questions: a) 100 grams of water are saturated with sodium nitrate at 40 o C. If this solution is heated to 70 o C, how much more can be dissolved? b) How many grams of ammonium chloride will dissolve in 65g of water at 70ºC? c) What is the solubility of sodium chloride in 100 grams of water at 50 o C? 7
8 Warm Up (Jan 18) 1. 10g of LiCl is dissolved in 150mL of water. What is the molarity? 2. You want to make 500mL of 0.1mol/L LiCl solution. a) How many moles of LiCl are needed? b) How many grams of LiCl are needed? 3. You have 50g of LiCl and want to make a 0.1mol/L LiCl solution. a) how many moles of LiCl do you have? b) How many Liters of solution will you need to make? 8
9 Warm Up (Jan 19) 1. STATE and EXPLAIN how adding a solute effects the freezing point of a solvent. 2. STATE and EXPLAIN how adding a solute effects the Boiling point of a solvent. 3. Which of the following would affect the freezing/boiling point the most? a) C 6 H 12 O 6 MgCl 2 c) AlCl 3 9
10 Warm Up (Jan 20) 1. Determine the concentration of 100mL of solution made with 10g of NaCl 2. What volume of 0.5mol/L NaCl solution contains 30 grams of salt? mL of a 0.5mol/L solution is diluted by adding 500mL of water. Determine the new concentration. 10
11 Warm up (Jan 21) mL of a 0.5mol/L solution has 400mL of water added to it. What is the new concentration? mL of a 1.0mol/L NaCl solution is mixed with 900mL of a 5mol/L NaCl solution. What is the new concentration? 11
12 Warm Up (Jan 25) 1. Calculate the mass of zinc chloride produced when 50g of zinc metal reacts with 50g of Hydrochloric acid (HCl) 12
13 Warm Up (June 16) Given the following reaction, calculate the theoretical mass of sodium chloride that will be produced from the reaction of 2.35g of sodium bicarbonate with excess hydrochloric acid. NaHCO 3 + HCl à NaCl + CO 2 + H 2 O If 1.45g were actually collected in the lab, what would be the percent yeild? 13
14 Warm up 1 (may 22) Use your solubility graph to answer the following questions: 1. How many grams of potassium nitrate will dissolve in 100g of water at 60 degrees celsius? 2. A saturated solution of ammonium chloride at 90 degrees is cooled to 10 degrees celsius. How many grams of solute will precipitate (settle out)? 3. How many grams of sodium nitrate will dissolve in 60mL of water at 50 degrees celsius? 14
