not industry..just a couple bottles from the lab. thanks for the information. I'm going to try calling the chemical supply company too

I accidentally stored some 2M NH3 in polycarbonate bottles , and now they're toast. It produced some white crystals and a brown suspension. I've done a little Googling and haven't found what the possible products are. Do you know what they could be? I am mostly concerned about disposal, and...

soak affected area in sodium thiosulfate? It should then form soluble silver complexes that can be washed away. labeled as photographic fixer in stores

thanks. I forgot about all the [A-] ions that came into the system as a result of the neutralization of the weak acid with NaOH.

Ka = \frac{[H+][A-]}{[HA]} [H+] = 2.2 * 10^-6 (got this from pH 5.65) [A-] = 2.2 * 10^-6 [HA] = 0.0027 mol/ 0.050 L

Homework Statement 1) A 0.682-gram sample of an unknown weak monoprotic organic acid, HA, was dissolved in sufficient water to make 50 milliliters of solution and was titrated with a 0.135-molar NaOH solution. After the addition of 10.6 milliliters of base, a pH of 5.65 was recorded. The...

Homework Statement I am trying to find out how to solve for x without a calculator. Basically where tan({x}) and sqrt{2}*cos{x} intersect.Homework Equations Find x in the range of 0 \le {x} \le \frac {pi}{2} The Attempt at a Solution I couldn't find out how to solve this without a...

is it possible to measure the maximum voltage that a bulb can take before burning out? I am interested in using rechargeable batteries for a 9v tactical flashlight that I have, but rechargeable 3v batteries actually have a peak voltage of around 3.85 when fully charged. As the bulb is kind...
