What do acids do in solution? O A. They increase the pH.
O B. They form hydroxide ions.
O C. They increase the [H").
O D. They dissociate into salts.

C.

Explanation:

The increase the [H+] (concentration of H+ ions)

However, they decrease the pH if acids are added to any solution. Since they have more [H+] ions, they increase their conc. in the solution

Explanation:

There are non-polar side chains also present in alanine. And, these non-polar side chains are involved in some hydrophobic interactions in active sideand then it changes into polar amino acid glutamate that will destroy the hydrophobic interaction.

Whereas in glycine there is only hydrogen present in the side chain therefore, it will not affect much.
