Calculate the concentrations of all species in a 1.20 M Na 2 SO 3 1.20 M Na2SO3 (sodium sulfite) solution. The ionization constants for sulfurous acid are K a 1 = 1.4 × 10 − 2 Ka1=1.4×10−2 and K a 2 = 6.3 × 10 − 8

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
