14. Tell how you can examine a substance to determine if it is pure or not. $400

15. Add water and filter it $400

16. Water is an example of this part of a solution. $100

17. Water is a solvent. $100

18. If you make a solution with orange crystals and water, the orange crystals are WHAT in the solution? $200

19. The orange crystal is the solute. $200

20. If you mix 5 g of salt in 20 mL of water, what will the MASS of the solution be? $300

21. The mass will be 25 g (20 mL of water = 20 g) $300

22. How does a solution compare to a mixture? $400

23. A solution is a type of mixture - it is REALLY well mixed (homogeneous) $400

24. When you pour a solution through a filter, what passes through the filter? $100

25. Filtrate (the entire solution goes through) $100

26. When you pour a mixture with soluble and insoluble substances into a filter, what DOES NOT get through? $200

27. The INSOLUBLE substance $200

28. What is the substance that gets trapped on filter paper called? $300

29. Residue/Insoluble $300

30. Daily Double

31. How can you get the solute out of a solution? $400

32. Evaporation $400

33. How can you tell if a solution is saturated? $100

34. You can see grains of solute in the solution. $100

35. If you start with copper sulfate and container that have a mass of 29.8 g, add copper sulfate to water until it is saturated, and find the new mass of the copper sulfate and container to be 22.1 g, how much copper sulfate was added? $200

36. 7.7 g of copper sulfate $200

37. When salt is added to ice, what happens to the melting and freezing point of ice? $300

38. The melting point and freezing point (which are the same things) of the ice goes down. $300

39. What would you expect the temperature of boiling salt water to be: 98ºC, 100ºC, 102ºC? $400

40. 102ºC (adding salt raises the boiling point) $400

41. When salt water is boiling, which of the following is happening:Water is evaporating, Water is dissolving, Water is disappearing, or Water is drying? $100

42. Water is evaporating $100

43. Look at the chromatogram. Which of the solutions was not soluble in water? $200

44. #3 - it doesn’t spread, so it isn’t soluble. $200

45. Which of the solutions in the chromatogram have the same solute in them? $300

46. 2 and 4 are the only ones you can tell just by looking (their bottom solutes line up). $300

47. Describe what happened in a test tube where big red crystals were mixed with water and the result was a red, transparent liquid with a few red grains on the bottom. $400

48. The red crystals DISSOLVED in the water (it was a solute, the water was a solvent). The solution became saturated so the last red grains didn’t dissolve. The crystals are more dense than water! $400

49. What is one thing that ALLOYS all have in common? $100

50. They are mixtures with at least one of the substances being metal. $100
