Consider a buffer solution prepared from hocl and naocl. which is the net ionic equation for the reaction that occurs when naoh is added to this buffer? oh– + hocl → h2o + ocl– oh– + ocl– → hocl + o2– na+ + hocl → nacl + oh– h+ + hocl → h2 + ocl– 2 points save answer question 5

The ionic equation is written below.

Explanation:

We are given:

A buffer solution that is prepared from HClO and NaClO.

The given buffer solution is an acidic buffer because it is made up form a weak acid and its salt.

The component that neutralizes the additional hydroxide ions from sodium hydroxide in the solution is HClO

The ionic equation for the reaction that occurs when hydroxide ions are added follows:

Hence, the ionic equation is written above.

  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-
