3. Inside a larger glass box, there is plenty of moist soil, a water tank with drip irrigation, and the seed of a fast-growing tree. The box is placed in the sun for a year, and the tree grows inside of the box. Did the total weight of the box and its contents increase, decrease, or remain unchanged. Explain your hypothesis.

1.       My hypothesis was that The house hold liquids such as lemonade clear soda and the clear shampoo would be acidic where as the baking soda dish soap and fertilizer would be basic. my hypothesis was somewhat correct all but the soda was correct by the looks of the colors.

2.      Some liquids required more because the strength of the acidity or base wasn't very strong thus requiring a larger amount of liquid added to the cabbage indicator.

3.      At the end of the experiment when the vinegar and baking powder were added together the colors mixed into a mix of the two more purple then the cabbage indicator and there was plenty of bubbles in the solution.

4.      Not very useful unless you know exactly what the colors indicate. Yes, all that would be needed is a ph scale.

5.      Acids and base indicators help us identify whether a substance is acidic or basic . They can be used to detect the nature of soil , samples etc which can be helpful.
