How long will the footprints on the moon last? A weak acid is only partially dissociated, with both the undissociated acid and its dissociation products being present, in solution, in equilibrium with each other. TSP is added in the spray water of the containment spray system (EAS) instead. Dihydrogen phosphate or dihydrogenphosphate ion is an inorganic ion with the formula [H 2 PO 4] −.Its formula can also be written as [PO 2 (OH) 2] −, which shows the presence of two O-H bonds.Together with hydrogen phosphate, dihydrogen phosphate occurs widely in natural systems.

When sodium bicarbonate (NaHCO 3), comes into contact with a strong acid, such as HCl, carbonic acid (H 2 CO 3), which is a weak acid, and NaCl are formed. Question 9 For an acid, we define the term monobasic as “an acid, which possesses only one proton that can be donated to a base during an acid- base reaction.” Likewise, dibasic for an acid means having two protons, which can be donated to a base. You have two buffer solutions 1) weak acid and its conjugate base 2)weak base and its conjugate acid. PO. Essentially, this lab proved how the concentration, the molar mass, and the equilibrium constant of either an acid or a base in an acid-base reaction are all related to each other.
