Why is the deprotonated form of P-nitrophenol more UV asborbant than the protonated form? My professor said we diluted the PNP in pH 10 buffer before analyzing it by UV spectrophotometry because the deprotonated form is more UV absorbant. Why is this?
Homework Answers
Answer: Deprotonated form of p- nitrophenol is more UV adsorbent than protonated form is due to more length of conjugation in Deprotonated form.
explanation with example is shown in the image attached:

3. To make a buffer solution, you can start with a solution of a known number of moles of the base form (A) and add a strong acid until you have neutralized the correct number of moles of the base to have the correct A HA ratio for the buffer you require. For the example using HF in the background information: a. How many moles of the base form (A) are required to start? HINT: The acid form (HA) will...

To add more information this was given to me for a lab that used
a weak acid and we added a strong base through titration. We just
observed how the ph changes. Later we then used a buffer with a
weak acid to see how buffers affect ph change. These questions are
basically surrounded around those topics to help us prepare.
However, I'm kinda confused about answering them because weak...

Writing Unix Utilities in C (not C++ or C#) my-cat The program my-cat is a simple program. Generally, it reads a file as specified by the user and prints its contents. A typical usage is as follows, in which the user wants to see the contents of my-cat.c, and thus types: prompt> ./my-cat my-cat.c #include <stdio.h> ... As shown, my-cat reads the file my-cat.c and prints out its contents. The "./" before the my-cat above is a UNIX thing; it...
