List of the Strong Bases (Arrhenius Bases)

Jun 25, 2019The strong bases are excellent proton (hydrogen ion) acceptors and electron donors. The strong bases can deprotonate weak acids. Aqueous solutions of strong bases are slippery and soapy. However, it's never a good idea to touch a solution to test it because these bases tend to be caustic. Concentrated solutions can produce chemical burns.

Structural analysis of the zinc hydroxide–Thr‐199–Glu‐106

The structures of these four mutants, as well as that of the bicarbonate complex of the mutant with Ala‐199, have been determined at 1.7 to 2.2 resolution. Removal of the γ atoms of residue 199 leads to distorted tetrahedral geometry at the zine ion, and a catalytically important zinc‐bound water molecule has moved towards Glu‐106.

List of Common Strong and Weak Acids

There are only a few (7) strong acids, so many people choose to memorize them. All the other acids are weak. The strong acids are hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, and chloric acid.
