This experiment uses cabbage indicator to show how indicators can be used to determine if a solution is an acid or base. The materials for this experiment are: cabbage indicator distilled water white vinegar baking soda notebook paper several small, clear cups a larger clear container and several household liquids such as: clear soda baking powder dissolved in water clear shampoo lemonade liquid soap and fertilizer dissolved in water. Your job is to observe the experiment and collect your own data from this demonstration. Be sure to record all your observations and data. To start, make a hypothesis of which of the liquids will be acidic or basic. You know that vinegar is an acid and baking soda is a base. So you will test these, and distilled water, as our controls. Fill each of three cups half full with the cabbage indicator. Then to the first cup, add about a teaspoon of vinegar. Add a teaspoon of baking soda to the second cup and a teaspoon of distilled water to the third. Record the color of the solution in each cup on your datasheet. Now you can use this procedure to test the other household liquids. Fill each of six cups half full with cabbage indicator. Add about a teaspoon of the household liquids to the appropriate cup. Be sure to clean and dry the spoon before measuring out each substance. Note the change in the color of the cabbage indicator and record on your datasheet. Test what happens to the color of the cabbage indicator when the vinegar and baking soda solutions are mixed in a neutralization reaction. Add the vinegar and cabbage solution to the larger container. Then add the baking soda and cabbage solution indicator to the vinegar solution in the larger container. Note and record all of your observations. Now, using your observations, present your findings. Write a summary paragraph discussing this experiment and the results. Use the following questions to help guide the content of your paragraph. What was your hypothesis? According to your data,
