The ph of a solution is 2.0. which statement is correct?
useful formulas include [h307- 107f. ro -- 10 poh, ph+poh = 14, and (h30 470h-) - 10-14
the poh of the solution is 12.0.
the concentration of oh-ions is 1.0 x 10-2 m.
the concentration of h30 ions is 100.0 m.
the poh of the solution is 16.0.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

the answer is symmetrical : )
