Draw aspartic acid (aspartate) at ph 1, ph 7, and ph 13. include hydrogen atoms.

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.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
