Draw aspartic acid (aspartate) at ph 1, ph 7, and ph 13. include hydrogen atoms.
2 answers:
Answer:
The structures are shown in figure.
Explanation:
At low pH (pH < 1.88) aspartic acid is completely protonated.
Both amine and carboxylic groups are protonated.
At medium pH (3.65-9.68) amine group is protonated and both the carboxylic groups are deprotonated.
At high pH (above 9.68) all the groups are deprotonated.

<u>Answer:</u> The concentration of hydrogen ion and bromoacetate ion is 0.0132 M and 0.0132 M resepectively and that of bromoacetic acid is 0.0868 M
<u>Explanation:</u>
We are given:
Molarity of bromoacetic acid = 0.100 M
Percent of ionization = 13.2 %
The chemical equation for the ionization of bromoacetic acid follows:
1 mole of bromoacetic acid produces 1 mole of bromoacetate ion and 1 mole of hydrogen ion
Molarity of hydrogen ion = 13.2 % of 0.100 =
Molarity of bromoacetate ion = molarity of hydrogen ion = 0.0132 M
Molarity of bromoacetic acid = Molarity of solution - Molarity of ionized substance
Molarity of bromoacetic acid = 0.100 - 0.0132 = 0.0868 M
Hence, the concentration of hydrogen ion and bromoacetate ion is 0.0132 M and 0.0132 M resepectively and that of bromoacetic acid is 0.0868 M
