We introduced ourselve in this video one by one and tell what sample we used. We also explained the function of uv-visible spectrophotometer and the precaution when handle cuvette and uv-visible spectrophotometer.

We explained the relevant why we choose the strawberry in this video. 

VIDEO 3

We explained the theory behind of uv-visible spectrophotometer which is how the sample should be prepared before the sample run using uv-visible spectrophotometer. We should know solvent transparency or polarity of the sample. Second we need to analyze the thermostatting of our sample.

VIDEO 4

In this video, we show how we do the dilution for acetic acid since this video was recorded before the task has been changed which is to ascorbic acid. We show how to dilute the acetic acid and carbonated drink with molarity and percentage that we want.
