| What flavors of Kool-Aid were used in the experiment? | cherry and grape. |
| How can you tell if a substance is soluble or not? | If it dissovles it is soluble (such as salt), if it doesn't dissolve it is not soluble (such as your shoe). |
| Which is more soluble, citric acid or salt? How can you tell? | Citric acid. It takes 60 grams of citric acid to saturate 50 ml and only 15 grams of salt. |
| Compare and contrast citric acid and salt. | They are both soluble (dissolve in water) but citric acid has a higher solubility. |
| How can you determine the amount of salt present in a saturated volume of water? | Weigh the salt and water together. Subtract 1 gram for each ml you have. Example: a 75 ml saturated salt water solution weighs 82 grams. 75 ml weighs 75 grams so you subtract 82 - 75 = 7 grams of salt. |
| What happens when a solution is made with water and two different solutes? | It depends. 1) both materials could dissolve (such as with salt, sugar, and water). 2) Nothing could happen (such as with a rock, your shoe, and water). 3) a reaction could take place (baking soda, calcium chloride, and water). |
| If you wanted one of the bags in the fizz quiz experiment to pop, how could you have accomplished this? | Add more solute and solvent. |
| How much salt does it take to saturate 50ml of water? How much citric acid? How much Epson salt? | 15 grams, 50 grams, and 25 grams. |
| Which combinations of chemicals did not have a reaction? How could you tell that they did not react? | DO NOT WORRY ABOUT THIS QUESTION FOR THE TEST |
