Lead makes chemical compounds in two main oxidation states: +2 and +4.
+2 compounds, also known as lead(II) compounds or plumbous compounds, are weak oxidizing agents.
+4 compounds, also known as lead(IV) compounds or plumbic compounds, are strong oxidizing agents.
Lead compounds are toxic just like the element.
The lead halides do not dissolve in water.
Lead(IV) oxide is the most common lead(IV) compound.
It is a black solid.
The lead oxides are all colored, while the other salts are white or colorless.
Lead nitrate and lead(II) acetate are the soluble compounds of lead.

+2 compounds
This state is more common than the +4 state.
These are weak oxidizing agents.
All but the oxides are colorless or white.

Lead(II) acetate, colorless soluble
Lead(II) arsenate, insoluble former pesticide
Lead(II) bromide, insoluble
Lead(II) carbonate, white, used as pigment
Lead(II) chloride, insoluble
Lead(II) nitrate, soluble, colorless
Lead(II) oxide, red or yellow
Lead(II) sulfate, white, found in lead acid batteries
Lead(II) sulfide, black, common as mineral
Mixed oxidation state compounds
Mixed oxidation state compounds contain lead in the +2 and +4 oxidation state.

Lead(II,IV) oxide, red, oxidizing agent
+4 compounds
These are less common.
They are strong oxidizing agents.

Lead(IV) acetate, oxidizing agent, colorless
Lead(IV) oxide, dark brown, oxidizing agentCobalt compounds are chemical compounds containing cobalt ions.
