Answer:
a) +1
b) 0
c) -1
d) -2
Explanation:
The aspartic acid is one of the twenty amino acids that make up proteins.
The equilibrium is in the image. pka for this molecule are 1.88, 3.65 and 9.60. A higher pH than pka will have as predominant form the molecule in the right and vice versa. The net charge in each molecule is in red.
Thus, for a pH of 1.0, as the pH is lower than first pka, predominant form will have a net charge of +1. If pH is 3.0, predominant form will have a net charge of 0. If pH is 6.0 predominant form will be the -1 and for a pH of 11.0, predominant form is the -2.
I hope it helps!
The net charge will be:
a) pH 1.0 = +1
b) pH 3.0 = 0
c) pH 6.0 = -1
d) pH 11.0 = -2
The aspartic acid is one of the 20 amino acids that make up proteins.

If pH is 6.0 predominant form will be the -1 and for a pH of 11.0, predominant form is the -2.
So, the charges for the following pH's are given here:
a) pH 1.0 = +1
b) pH 3.0 = 0
c) pH 6.0 = -1
d) pH 11.0 = -2
