These are some of the results we got from our acid + base reactions (citric acid + baking soda + water) and (tartaric acid + baking soda + water).

| The mixture fizzed and the bag filled with a gas. |
 |
| The reaction made the liquid go COLDER. This is an endothermic reaction. It uses heat from the environment rather than producing heat. |
 |
| Lighting a match to see if the gas would make the flame brighter (oxygen) or put it out (carbon dioxide). |
Way to go Room 12! I am very impressed you can make your own litmus paper! Perhaps you can show me how!
