-----Purity determination of calcium carbonate and calcium hydroxide
Q. Dear readers,
I would like to know, how the calcium hydroxide purity can be determined in a lab. I hope that someone can help me by giving full detail how the analysis can be carried out.
Thank you.

It is not obvious what you want. Hydroxide strength, % of calcium, or what trace elements. It makes a huge amount of difference in the equipment required.

Hi Reegah.
I'm sorry that I don't know lab analysis myself, but many of the readers do. As James says, it can be hard for them to know what you're actually looking for. If you don't quite know how to express your question to satisfy them, the easiest way to put it into context for them is often to simply describe your situation like "I'm a buyer for a commodity chemicals warehouse...", or "I'm formulating breakfast cereals...", or "We may have accidentally mixed some cadmium oxide into our calcium carbonate..."
Best of luck.
Regards,
Ted Mooney, P.E.
