To what extent was this experiment useful in determining pH? Could a specific pH be determined using this procedure?

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.

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.
