Answer #1

1. If the extraction step did not completely isolate the analyte, it will highly impact the results of Uv-s and fluorimeter. Let's understand this by an example. You want to measure the UV-vis spectrum for compound A, and if the extraction step did not completely isolate A, so it may have some contamination of Impurity(I), so if you will measure the sample in UV‐vis and fluorimeter, your result will be for A + I, which will differ from pure sample A. So, it's advisable to completely isolate the analyte during extraction step.

2. Acid-Base titrations are one of the other technique to determine the concentration of the analyte.

Activity 1: Scientific Reports You may have heard the question “If a tree falls in a forest and no one is around to hear it, does it make a sound?” A similar question can be asked about experiments. “If a researcher performs an experiment and never publishes the result has science been performed?” Many people would say no because science is the accumulation of knowledge. If the results of an experiment are not published, knowledge is not gained. The final...

Diffusion of gases across a permeable membrane 1. How long did it take the O2 levels to become about equal outside and inside the cell? What happened to those levels after they became about equal over the additional 10 seconds? Why did this happen? My answer: It took 6 seconds to become equal. After they became about equal over the additional 10 seconds they fluctuate back and forth as equal equilibrium is achieved. 2.Cell use O2 and produce CO2 as...
