The ionization constant (Ka) for a weak acid can be used to calculate the concentration of H+ ions in solution. Since the acid is triprotic, the Ka value will be used three times to calculate the concentrations of all dissociation steps. The H+ concentration can then be converted to pH using the formula pH = -log[H+].

Orthophosphoric acid is commonly used in titrations because it is a triprotic acid, meaning it can donate three protons in a titration reaction, allowing for multiple equivalence points to be observed. This property is useful in complexometric titrations where multiple reactions may occur. Additionally, orthophosphoric acid is stable and inexpensive, making it a practical choice for titrations.

A weak acid is a substance that only partially ionizes in water, resulting in a low concentration of hydronium ions (H3O+). This leads to a pH closer to neutral (7) compared to a strong acid, which fully ionizes and has a lower pH. Examples of weak acids include acetic acid and citric acid.

H+ + OH- ----> H2O is the basic reaction for neutralization. But this would not be balanced if a diprotic or triprotic acid were used. There is strictly speaking not enough information to answer the question.

No acetic acid is not polyprotic. Although the multiple Hydrogen's may lead you to believe it is. It is monoprotic due to the fact that only one of those hydrogen's is structually attached to an oxygen. H's bonded to carbons are no protic. The number of hydrogen atoms present in one molecule of acid cannot always be used to classify the acid as mono-, di-, or triprotic. For example, a molecule of acetic acid contains four hydrogen atoms, but it is monoprotic. Only one of the hydrogen atoms in acetic acid is acidic or ionizable.

Both formula mass and molecular mass refer to the mass of a compound relative to 1/12 of the mass of a Carbon-12 atom. However, molecular mass is specific to molecules – that is, only for a minimum of 2 atoms held together by covalent bonds. As an example, you can say that the molecular mass of water is 18. You can also say that the formula mass of water is 18. You can say that the formula mass of common table salt, NaCl, is 58.5, but it would be inaccurate to say that the molecular mass of NaCl is 58.5, since NaCl is not a molecule. The difference is not in numerical value but merely terminology.
