Chapter 4: Elements, Atoms & Isotopes
Acid-base nature of the oxides in oxidation state +2 and +4. CO is neutral, CO2 is acidic. SiO & GeO do not exist. SiO2 is weakly acidic. GeO2, SnO, SnO2, PbO and PbO2 are amphoteric. Reactions of the oxides in the +2 and +4 oxidation states to show their a. cidic or basic nature. Since CO is neutral, it reacts with neither acids nor bases. ................
