Answer: Independent variable is the Vitamin C and the ashy skin is the dependent variable.
Explanation:
We can change or manipulate the independent variable of the reaction and such change can be observed on the dependent variable. The dependent variable yields the results of the experiment and changes in the dependent variable must be observed attentively to frame the results.
Here, vitamin C is the independent variable whose affect has to be observed on the ashy skin which is the dependent variable of the experiment. Steps of the experiment:
1. We can apply Vitamin C in a form of solution on the ashy skin.
2. Observe the changes on the skin directly and apply for 2-3 times in a day.
3. Observe the changes on the skin after a week.
