The active metals in columns 1 and 2 of a wide form periodic table cannot be reduced to elemental metals by electrolysis in aqueous electrolytic cells, because any atom of elemental active metal that might be transiently produced, by reduction of a positive ion of the active metal to a neutral atom, will react almost instantaneously with two nearby water molecules to produce hydrogen gas, hydroxyl ions, and regenerated positive ions of the active metal.
in aqueous medium, H2 is evolved at the cathode, instead of depositing metals of group 1 or 2.
because they produce H2 gas at the cathode instead of being getting deposited.
Non-aqueous titration is used in pharmaceutical applications to determine the purity and concentration of certain drugs or active pharmaceutical ingredients. This technique involves using a non-aqueous solvent, such as methanol or acetonitrile, as the titrant and titrating it against a solution containing the drug or active ingredient. Non-aqueous titration is particularly useful for compounds that are not soluble in water or are prone to hydrolysis in an aqueous medium.
In Group 1. (The extreme left of the modern Periodic Table)
group #1 on the periodic table is called alkali metals, has one valence electron, and is the most active metal group.
The most active elements are in group one and two on the periodic table and are always found in nature combined with other elements. The most active metals are in group one, which is the alkali metals, they wouldn't be in group two. (if you need more information) http://www.chem4kids.com/files/elem_alkalimetal.HTML
The most active group of nonmetals are those in Group 17, and these are the halogens. The list is headed by fluorine, which is the most reactive element of the group and of the Periodic Table as a whole.
the most active is oxygen
Hydrogen is an extremely active element.
Francium

It is fluorine. Fluorine is part of the halogens they are very active nonmetals.

In general, no - the active medication starts to break down in solution.
