Question

Need help, please. Not too sure why my answer is incorrect. Please show all steps/work.

You have discovered a new amino acid. You find that its side has a pka-8.00 what percent of this side chain would be deprotonated at pH-8.50
76.0X
Please answer to three significant figures 31.6
Feedback:
First, using the HH, plug in the numbers given to solve for the ratio of A/HA
Let's say the number A/ HA= 5, this means that 5 side chains are deprot for every 1 protonated side chain. Therefore the total number of side chains would be 1.5 (prot + deprot)
To find the percentage deprotonated (this is from your math classes) = A/ total side chains (A+HA)* 100 (e. if we continue with the numbers above, percentage deprotonated would be 5/1.5* 100 or 33.33
