How pH affect ionic bonding?

Answer 1

At low pH the over all net charge, for example amino acid residue ( which is connected by by ionic bonding) is going to be protonated which means there will be no ionic bonding at very low pH. As you raise the pH depending on the given pKas part of the residue starts to deprotonate which also could alter the net charge i.e the the ionic bonding is going to be affected.

Answer 2

pH can affect ionic bonding by changing the concentration of hydronium ions in a solution, which can influence the stability and formation of ionic bonds. A higher pH (more basic solution) can decrease the concentration of hydronium ions, making it harder for ions to dissociate and form ionic bonds. Conversely, a lower pH (more acidic solution) can increase the concentration of hydronium ions, promoting the dissociation and formation of ionic bonds.
