or neutral. Bases fall on the high end of the scale, above 7, with weak bases (i.e. baking soda) being around 7-10 and strong bases (i.e. bleach) being around 10-14. Bases typically contain an OH-ion, meaning an oxygen atom bonded to one hydrogen atom. Acids, on the other han...
keeping oxygen out and carbonation in, and is mainly used to package food and drinks. Packaging made from this type of plastic can be difficult to clean, and higher temperatures can cause toxins to leach, so it is recommended tonot reuseproducts made from PET. ...
cyanide binds to cytochrome oxidase within the mitochondria and disrupts cellular respiration.
