On the opposite end of the pH scale, an acidic drain cleaner isn't much better. Products that contain sulfuric acid can also corrode pipes, and like products containing sodium hydroxide, they are bad for septic systems and the environment in general. Enzymatic drain cleaners are safer, but th...
Plus, a lot of these drain cleaners are made with really strong stuff like lye and sulfuric acid, which can let off nasty fumes that are dangerous to breathe in. On top of harming nature, these store-bought drain cleaners usually cost more than natural options. And if one of these cleane...

water-removing cleansers, but they don't work for everyone. Even commercial-grade cleansers with bases made from an acid such as sulfuric acid either work really well or not so great depending on the water makeup. And a number of people have sensitivities or bad reactions to strong ...
We found that it’s essential to locate this specific spot. Otherwise, even if you clean up the glass fibers, they will continue to escape if the source is not addressed. Once you have identified the leakage point, you can bag up any loose fiberglass on the mattress surface. However, if...
forest firesandlightningstrikes also add to the man-made pollution. SO2 and NOx become acids when they enter the atmosphere and react with water vapor. The resulting sulfuric and nitric acids can fall as wet or dry depositions. Wet deposition is precipitation: acid rain, snow, sleet or fog....
The modal fabric production process again bypasses the aging process that usually occurs at this point, and this syrupy substance is immediately forced through a spinneret to create fibers. These fibers are then immersed in sulfuric acid, stretched, and formed into yarn. The resulting yarn is ...

Decant three parts concentrated sulfuric acid into one measuring cylinder and one part 30% w/v hydrogen peroxide into another measuring cylinder. Use two different-sized measuring cylinders to avoid mixing them up. Place a clean Pyrex beaker onto a heatproof mat in the fume cupboard. Pour the ...
