It depends on the molecule of course.
some molecules have a soft hydroxide group, that is a OH sticking out somewhere that isn't all that closely held. Increasing the pH in the environment of such a molecule can result in a free hydrogen ion latching onto the hydroxide group and forming a water molecule - in effect removing the hydroxide group from the molecule. This is a process known as dehydration - the removal of water. Dehydration is both an important and detrimental process in making Urea, a nitrogen rich fertilizer.
Some slightly complex molecules we 'bend into a new shape' in the presence/absence of hydrogen ion. The electro-presence of hydrogen ions affecting the arrangement of certain hydrogen bonds with in the molecule. This is the case with some pH indicators. This bending and refolding can occur countless times as there is no net change to the molecule.

Industrial applications of common ion effect?
buffer solutions are the use ful applications of common ion effect they are important for biological applications[some enzymes can only work at a specific ph,the ph of gastric juices is 1.5. chemical applications fermentations,dyeing need a maximum ph.
Effect of Diluting a buffer?
The buffer capacity increases as the concentration of the buffer solution increases and is a maximum when the pH is equal to the same value as the pKa of the weak acid in the buffer. A buffer solution is a good buffer in the pH range that is + or - 1 pH unit of the pKa. Beyond that, buffering capacity is minimal.
What effect does increasing the number of carbons have on the boiling point?
Increasing the number of carbons in a molecule increase the boiling point in the wast majority of cases.
What is the full name for te buffer?
It is a buffer used in biology. "te" is derived from its components: t from tris, a common pH buffer, and e from the EDTA, a molecule. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.
Does starch have a pH?
everything has a pH
PH effect on enzymes?
A change in pH can alter the ionization of the R groups of the amino acids. When the charges on the amino acids change, hydrogen bonding within the protein molecule changes and the molecule changes shape. The new shape therefore may not be effective
What the effect of activated carbon on pH?
it lowers the Ph
What is varied when tested the effect of pH enzyme activity?
The pH is varied to effect, by its affect, this test.
What is Effect of pH in the solubility of weak acidic drugs?
Certain functional groups on the chemical structure of drugs are capable of being protonated/ deprotonated based on the pH of the solution (amine groups as well as carboxylate groups are capable of this). Changing the pH of the solution can change the physical chemistry of a drug by adding or removing protons at certain sites of the molecule. Depending on the molecule, this will either increase or decrease the solubility of the drug.
