Concept explainers
(a)
Interpretation:
The balanced equation for formation of dihydrogen phosphate from Phosphoric acid in water should be explained.
Concept Introduction:
The law of conservation of mass states that no atoms can be created or destroyed in a
Bronsted Acid: An acid donates (loses)
Bronsted Base: A base accepts (gains)
(b)
Interpretation:
The net ionic equation for the ionization of dihydrogen phosphate in water and the nature of the dihydrogen phosphate should be explained.
Concept Introduction:
The law of conservation of mass states that no atoms can be created or destroyed in a chemical reaction, therefore, the number of atoms present in the reactants is equal to the number of atoms present in the products.
Bronsted acid: An acid donates (loses)
Bronsted Base: A base accepts (gains)
Amphiprotic substance: An amphiprotic substance is a substance that can donate or accept a proton.
