a. AlCl3 + Cl- -> AlCl4-
b. BF3 + C5H5N -> C5H5N -> BF3

Citric acid, H3C6H5O7, is present in citrus fruits. It is a triprotic acid (i.e. it can donate three protons per molecule in an acid-base reaction) with acid- dissociation-constant values of Ka1 =...

The decomposition of hydrogen peroxide is catalyzed by iodide ion. The catalyzed reaction is thought to proceed by a two-step mechanism:

1. H2O2(aq) + I-(aq) → H2O(l) + IO-(aq) ...
