    Wrong chemistry! That stuff is basic, you need acidic to test for Zn. Just take a few drops out of your car/truck battery. You will never miss a few drops. That is H2SO4 in your battery, but HCL is more aggressive for metals testing, as it's hydrogen ion concentration is much greater.

    Not too sure about 'wrong chemistry' since the stuff contains 5-10% hydrochloric acid, at least as per the MSDS. http://www.rbnainfo.com/MSDS/US/LIME...20EN%20GHS.pdf

    Substance/mixture : Mixture
    Hydrochloric acid 5 - 10% 7647-01-0
    Amines, tallow alkyl, ethoxylated 1 - 2.5% 61791-26-2
    Alcohols, C12-15, ethoxylated 1 - 2.5% 68131-39-5


    Likely 'it's too diluted' for our purposes.

    Wife has a very old bottle of the stuff and the label indicates no acidic content. They must have changed the make-up over the years.

    10% HCl is strong enough to get a reaction.

    You can buy a gallon of HCl cheap at a pool supply store. Use it to test the unknown metal and then keep it around. It can be quite useful for removing corrosion from metals, if you are careful handling it.

    No doubt, but I had presented the 'make your own' as a option for folks who do not have a wooden barn or shed to store the stuff. From my experience the acid tends to leach through the plastic bottles in something similar to vapor and will cause damaging rust/corrosion to any nearby metal (and that includes the very nails/screws holding a wooden structure together).

    (NODS HEAD VIGOROUSLY IN AGREEMENT) Lordy, yes. I'm still finding rusted tools in my shop from when I made that mistake, usually ones stored within three feet on the bottle. I'm just hoping the water heater and furnace on the side furthest away are OK.

    That’s interesting. I never experienced or even heard about that. Luckily I do have a barn where I store mine, but I wonder what happens in the stores where it is being sold and there are many gallons of it. Perhaps if there is enough turn over, it doesn’t have an effect. I think I have some glass half gallon jugs around to store mine in. I’ll have to use a cork stopper and not the metal caps. Will much seep through the corks?
