What I could do to my soil to reduce oxalate content in my garden vegetables?

Tomatoes and beans are high oxalate foods and a problem for some people on a low oxalate diet-(me, lol) Unfortunately, they are my favorite veggies to eat and grow. Certain growing conditions cause variances in the oxalate content, but what those are, I don't know.

can i make hydrogen sulfide by reacting a sulfide with oxalic acid?

Hi, i am trying to make hydrogen sulfide for the purpose of reacting it with ammonium hydroxide to create ammonium sulfide. however, since my parent think that concentrated hydrochloric acid is too dangerous to work with, especially since i can only get huge 20L bottles of it, i have decided to quest for a new acid to react with calcium polysulfide, to get hydrogen sulfide, thats when i came across solid oxalic acid. at first glimps, i saw that it said, hazardous, extremely corrosive acid, i thought "yes", this would work, i could react this with the lime sulfur , but then after some research i discoverd that no-one in the history of the world has ever documented the practical reaction of oxalic acid with a sulfide, in order to make hydrogen sulfide. so i want to ask , will oxalic acid, when mixed with calcium polysulfide, generate hydrogen sulfide? another reason though i might point out why i dont think oxalic acid will react with calcium polysulfide, is because it is a solid crystal acid, one that does not evapourate into gas like sulfuric or hydrochloric acid, and i cannot find anywhere documented either of non gaseous acids being able to react with calcium sulfide to make hydrogen sulfide, according to what i have found out, only nitric, sulfuric and hydrochloric acids will work. but this is also the reason i want to use oxalic acid over hydrochloric because i want to boil off the hydrogen sulfide through a tube and into concentrated ammonium hydroxide, but if there is hydrochloric acid in the solution, it would very likely boil off as well, which would be something of a hassle.

Rust in old water pipes? Answered

Problem: The house I moved in to still has galvanised steel pipes for all water connections. The rust and deposit build up is so bad that with a pressure nozzle on the garden hose I reach aroun 20m from the tap near the mater meter but only around 5m in the backyard. To make things worse these restrictions affect the hot water. If I open the hot water tap and then open a col water tap the hot slows and then the flow fully stopps. The landlord already stated he has no intentions of replacing the pipes at this stage as it is quite costly. The possible solution: I was thinking of flushing the system with oxalic or phosphoric acid to break down rust and deposits. The questions: Has anyone tried this and has some feedback on how good or bad it worked? Do I have to fill the entire system with the acid or is it enough to get a few liters in and hope it will spread/dilute through the system within 24 hours? Is it advisable to use a bucket and aquarium pump (probably something stronger) to circulate the acid through the pipes?

Restore an old steam trunk

This is a quick CALL FOR HELP regarding the restoration of an old steam trunk. The idea is to convert it into a stylish coffee table and storage space and I could really use your suggestions on how to strengthen it's construction and embellish it's exterior. With your help I'll go forward with the plans and publish my progress here. The timeline is also important since the trunk occupies considerable space in our little apartment, so ideally I would like to finish all the woodwork within the next couple of weeks (until beginning of May 2012). The exterior and small touches could wait. HOW I FOUND THE TRUNK I found the trunk next to our dumpster 2 days ago and I just couldn't believe it - Who would throw away such a beautiful thing? - Was I such a good boy that Garbage Santa gave me this gift for Passover/Easter? I hauled it to our flat - my wife asking me what did the cat drag in this time.. (she just loves it that pack our home/car with stuff I find) she couldn't believe her eyes when she saw it. Since we live in a flat with almost no storage space it's very difficult to put together all the needed materials for this project, plus, I insist on doing it with recycled wood (what I find lying around) so to minimize costs. Requirements: @ The trunk should be sturdy (kids might climb on it at some point, ~20kg on the lid). @ It will probably hold a big pile of magazines (10 - 40 kg on the bottom), pillows/blankets. @ I want to add 4 or 6 casters to the bottom so it'll be more mobile. @ I think there should be additional internal support where the leather handles are so when they're pulled I won't be standing with one side of the trunk in my hand. Materials: - Wood - I currently have a solid pine wood dresser in my car, ready to be disassembled for it's beams (?) - OSB - there is some around where I work, 10mm thick. I'll try to find any more materials you'll suggest. Tools: - Drill (and screws) - Glue gun - Staple gun - Carpenter's glue - Hammer - Oxalic acid - Will need to finally buy a Gigsaw.... Trunk internal measurements: Length - 980mm Height - Box - 485mm, Lid - 105mm Depth - 559mm The trunk's side thickness is about 7-8mm made of ply wood covered with black leather. I has seen better days, but it's in relatively good condition. We were thinking of gluing the black surfaces with some sort of bright colored wallpaper (leaving the black leather lining with pins visible) so it would give it some sort of lightness - less bulky. I was also thinking of maybe gluing some sort of fabric with a cool vintage design, but it seems like a lot of work making it look good, stretched with no wrinkles, excess glue... plus it'll probably gather a lot more dust than a wallpaper (I'm allergic). There are two issues that concern me: 1. A fear that this current design isn't strong enough for a clumsy family. 2. I want to attach the corner supports and lid OSB without needing to drill the exterior (too much). I thought of using a lot of glue, but I'm not sure it's the best way to go. What do you think? I'm also attaching this design in Google SketchUp.
