If you soak something really dirty, like a plunger or soiled diapers in a pail of bleach water, say for an hour, or even a day, is the bleach water now contaminated? I don't really understand how bleach works. I know it kills germs, but does it eat up and kill everything that goes into it, like a vat of acid would a plastic spoon? That's how I have alwasy envisioned it. I ask because I used quite a bit of bleach water to soak a plunger in, all visible soil and grudge already removed, and I am wondering if I could scour the tub and commode in the remaining bleach water or if its contaminated and I should empty it and start anew. May sound like an odd question, but I am a single woman at present on a fixed income, albeit temporarily, and economizing has proved most helpful. Thanks!

this for a project in my chem class. it is supposed to be one of those real life problems and i need to figure out away to remove water from popcorn and i came up with freeze drying. so i need to remove the water from the popcorn in a matter of a few hours. if the freezer is cold enough then the water will sublimate out in a few a hours so i need to know how cold the freezer needs to be.

I already know that you are not supposed to mix bleach and ammonia, but I was wondering what happens bio-chemically in your lungs and mucous membranes if the fumes are inhaled?

I know the reaction goes something like
2NaOCl + 2NH3 --> 2NaONH3 + Cl2.
In which the Cl2 is the gas

i also need the basic facts about chlorine for my element project. For example, like HOW DID THE ELEMENT GET ITS NAME, PHYSICAL PROPERTIES (WHAT IT LOOKS LIKE, FEELS LIKE, SMELLS LIKE, ETC), CHEMICAL PROPERTIES (HOW REACTIVE IS IT? WHAT DOES IT REACT WITH?), INFO ON WHERE IT IS NATURALLY FOUND, HUMAN USES (OTHER THAN FOR NUTITION) FOR PURE ELEMNT, COMPOUNDS CONTAINING ELEMENT, OR MIXTURES CONTAINING ELEMENT, ECOLOGICAL ISSUES FOR PURE ELEMENT, COMPOUNDS CONTAINING ELEMENT, OR MIXTURES CONTAINING ELEMENT, HUMAN HEALTH/NUTITION INFORMATION. NEGATIVE AND POSITIVE EFFECTS ON BODY FOR PURE ELEMENT, COMPOUNDS CONTAING ELEMENT,OR MIXURES CONTAING ELEMENT, HISTORICAL INFORMATION. DID IT PLAY AN IMPORTANT ROLE IN HISTORY?

How do you find the concentration of HCl in 25mL of DI water with .1324 grams of Na2CO3 added to it to keep it constant? This was done by creating a standard solution of approximately .1M solution but now I'm trying to find the exact and am confused with the added Na2CO3. The amount of HCl added to the 25 mL of DI water and .1324 grams of Na2CO3 is 29.066 mL (done by titration)...so where do I go from there to find the concentration?
