Active Carbon and Calcium Sulfite to filter the water.
Although people have Sulfite reactions, it is not clear whether this is a real allergy
or other reaction.
The presence of sodium-containing sodium salts(Sulfite, metabiSulfite, thiosulfate)
is a guarantee of the effectiveness and stability of the agent containing rutin.
It is also
possible to carry out a metathesis reaction with ammonium Sulfite and ammonium polysulfide,
and then remove the willow to obtain ammonium thiosulfate by freeze crystallization.
In acidic solutions Fe2 is oxidized to Fe3( hydrogen peroxide acting as an oxidizing agent): 2 Fe2( aq) H 2O 2 2 H+( aq) 2 Fe3( aq) 2 H 2O(
l) and Sulfite( SO2-
3) is oxidized to sulfate SO2- 4.
