What is the general name of aqueous compounds where hydrogen is a cation?

Acids are the general name of an aqueous compounds where hydrogen is a cation.

An acid is a compound or ion which has ability to donate ion or proton. When acid is dissolved in aqueous solution, then it is capable for donating proton or ion.

General equation in aqueous solution:

HA is an acid which dissociates into .

Thus, general name is acid.

14 days is the half-life of phosphorus-32

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
