question: if i am given a certian pH lets say of +2 rather than a pH of +1 for the "acidic solution" and the pH in this example is of that of a non polar acid (alanine lets say) changes to +1;

does the pH number dictate how many hydrogens (protons) are added to lets say that amine or carboxylicc acid (lest say pH change of that being +2 rather than +1) ? What determines the number of protons being added to that amino acid on the carboxylic end? i know a carboxylic acid can take up to four protons being added on the molecule i hope this made sense - if anyone answering needs more clarification please let me know

Problem

What would charge would you expect on alanine when placed in a solution with a pH of 1.00?

Answer

+1. Since alanine is nonpolar, we know that the only parts of the amino acid that can be charged are the N-terminus and the C-terminus.

In an acidic solution, there is an excessive amount of protons available to protonate the amino acid. As a result, the carboxylic acid end and the amine end will both be fully protonated. This will result in an overall charge of +1, due to the nitrogen having three hydrogens attached.

Question

Let's say I am given a certain pH of 2.00 rather than 1.00 for the "acidic solution" and the pH in this example is of that of a non-polar acid (alanine) changes to +1.

Does the pH dictate how many protons are added to amino or carboxyl groups? What determines the number of protons being added to that amino acid on the carboxylic end? I know a carboxylic acid can take up to four protons being added on the molecule.
