lead (ll) oxide

timbuk2 - 23-4-2015 at 10:28

Can somebody tell me what lead oxide is used for? I found a small bottle of this and its quite heavy, hence the name. It looks like a heavy liquid kind of a pinkish color,i wont open the bottle because i dont know what its for. Im curious what its used for tho. My brother who passed recently was into chemistry and had numerous chemicals and lab supplies this is how i got this .

Lead (ii) Oxide (PbO) can be used as a precursor to lead compounds; also it can be used sometimes for condensation reactions in organic chemistry. Other than science I know it has be used in ceramics as a component in glazes though due to it's terrible toxicity this is being phased out alongside it's use in paint.

However, the pink colour and that it is in a liquid form leads me to think that either it is not PbO as it practically is white and insoluble in water, alcohols and most other solvents. The weight would lead me to thinking that it would be something of a higher Relative Atomic Mass, such as Lead. Sorry I can't be of more use

How about bismuth subsalicylate?

It's pink, and fairly dense-ish. Also, water soluble.

Is it labelled? Lead(II) oxide is a white, heavy solid.

If it isn't labelled then guessing is a thoroughly bad idea...

Unknown dense Pink liquid chemicals are generally used in the practice of visiting the local toxic waste disposal plant for safe disposal.

If it is unknown, and you don't know how to identify or deal with it, i'd suggest playing safe, not opening it and certainly not messing with it.
