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 [1]: https://i.sstatic.net/4YZ2B.png
