Talk:Sodium hydroxide
From Academic Kids
Both this page and the KOH say their compound is more commonly used for biodiesel because it does not clump as much. They can't both be right.
Moved this text:
It is also a traditional ingredient in the making of soap, and for this
purpose was historically obtained in an impure form by steeping wood ash in
water for a long period.
to the KOH entry and added a bit to this entry about the confusion of NaOH and KOH by both of them being called "lye."
About language and communication of ideas.
I would like to see some text here about lye. How was the substance originally created/discovered? What was it originally used for? From which base substances is lye commonly created from today...?
So often in the field of chemistry, the conversation deteriorates into a speculative maze of generalized theories of chemical interaction. I find it more educational to hear of known observations and known physical building blocks of chemicals in terms of the real hands on knowledge that a person has who works in a factory.
This genre of writing would communicate more effectively to casual readers who are interested about these guild issues. --- Rainbird 21:12, 28 Sep 2004 (UTC)
