Boric acid is a weak acid or strong acid
WebA strong acid, you will recall, is one that is stronger than the hydronium ion H 3 O +. This means that in the presence of water, the proton on a strong acid such as HCl will "fall" into the "sink" provided by H 2 O, converting the latter into its conjugate acid H 3 O +. In other words, H 3 O + is the strongest acid that can exist in aqueous ... WebDas polyelektrolytische Verhalten von Poly(vinylalkohol)-Borsäure-Komplexen wurde untersucht.
