... H2PO4 can either accept a proton, H, to become H3PO4 and thus behaves as a Brønsted base, or can donate a proton in water to yield H and HPO42, thus behaving as a Brønsted acid. HSO4 can either accept a proton, H, to become H2SO4 and thus behaves as a Brønsted base, or can donate a proton in w ...

... Amount is another physical quantity like mass, volume, length, time, etc. It gives us an alternative, and very useful, way of expressing how much there is of a substance. We can express how much there is of a substance as a mass (by reference to a standard mass), as a volume (by reference to a stand ...

... Some students completely ignore the charges when they look at formulas of ions; hence they see no difference between molecules and the ions with the same number and type of atoms, e.g., SO3 and SO3 2– or NO2 and NO2 – . It is important to point out that an ion’s formula is incomplete unless the prop ...
