Calcium deposits in pipes. Is there any way to get rid of it?
Q. I recently moved into a 10 year old house. The house set on the market for about 6 months unoccupied until we moved in. We quickly noticed that many of the faucets are really restricted because of calcium deposits. In fact it clogged up the washer machine within a week. It seems the faucets we use on a daily basis has gotten a lot better but the other faucets are nearly not working. Is there anything I can do? Is it just at the faucets and I need to replace them or does it run all the way through all the pipes. Please help I'm running out of water! I have removed all the screens but it is further into the faucets than that. As if the whole faucet has a buildup around it. Cleaning the screen improves it but only for a short time.… [cont.]

A. unscrew the bottom of the faucet (where the water comes out) there is a screen in there that acts as an airator. It also clogs up with lime. run the water for a minute or two and clean the screen really good. There are also screens on your washing machine inlet. If the water is really hard, you may want to consider a water softener. Wow then, this sounds like some tough stuff! Do you see "floaties" in the water when you hold it up to the light? Is this well or municipal water? Have you had a free water test done at a water treatment or well drilling business? what were the results for hardness? Short of ripping out all of the plumbing, the hydrochloric idea might work. You'll need a chemical feedpump and solution tank, 3-5 gallons of… [cont.]

Heavy calcium build up on pool tile; What is the best product to use to remove it?
Q. I have what appears like heavy calcium build up on my pool tiles. What is the best product to use to remove it. OK, it might be calcium and lime... What heavy duty product is there that works fast and can cut through this chalky muck?

A. Calcium build-up on tile should be cleaned weekly using comet or some such. Much easier to clean as you go instead of waiting til it's a monumental job. Best product I've found for removing it is called "Scale-Be-Gone". The pool store might have to order it for you, though. It is a gel. Paint it on and let it sit until it stops bubbling. Then rinse. Caution: the stuff bites so be really careful when using it. It is a combination of 3 acids and will burn skin severly. Use rubber gloves. DO NOT use on anything except pool tile. It will burn holes in other types of tile.

How much calcium carbonate is there in limestone ?
Q. I have to do an experiment for school (for chemistry more specifically) and have to do the research ourselves. I want to know how do you find out how much calcium carbonate is there in a limestone. What are the apparatus used and what is the procedure ? I need this info to write up the lab report. Any help will be appreciated.

A. While the first answer is essentially correct, limestone IS calcium carbonate, it is NOT pure calcium carbonate. most limestones contain other materials such as magnesium carbonate and silica. You can measure total carbonates by titration with an acid such as HCl. Alternatively, you can dissolve the limestone in a strong acid such as HCl or H2SO4 and then determine any residue left by weight.
