Hard and Soft Water

I remember I did a science project once that tested water quality. I had a device that basically consisted of two rods connected to a lid. When you placed the lid on the jar (which was full of water) the rods would be submerged in the water. Then you plugged it in and the elecrical current between the two rods caused all of the disolved things in the water to sink to the bottom. It was really pretty disgusting once you see everything you are drinking. Anyway I think it was called electrolysis and I'd imagine that would work to soften water... once you filtered out the junk that settled on the bottom.

Well there are 4 compounds that can make water hard.... and two of them are thermodecomposable

Could you not just distill it?

i culd distill it but apparently my teacher said sometimes the mineral could be carried by the steam....and wut about my limestone idea..is that ok?

I'll admit to having never heard of your limestone method. By filtering out the limestone, do you mean something like reverse osmosis, or does it somehow precipitate after attracting those other minerals. Interesting technique if it works.

I understand some boron compound will stay with the steam, but haven't heard of any others. I'm a bookkeeper, not a physical chemist.

i wus kinda planning on just flitering our the limestone by like a...ummmmmmm kinda like a cofee filter wus my idea...im not exactly sure about wut u are talking about?

Give it a shot, but solutions are notoriously difficult to filter.

Cool it down a lot.
