I have been usung 1 teaspoon of .1 sufite solution in place of campden tablets as well as for the acid testing.
I decided to make my own .1 solution fron sodium metabisulfate crystals.
i found the symbol for the compound to be Na2S2O6
than i went to the periodic table and came up with the folowing.
NA2=2X22.989= 45.978
S2 = 2X32.06 = 64.12
O6= 6X15.999= 95.994
FW(formula weight)=206.92
the molar solution formula is
FW X % of solution desired = GRAMS/ONE LITRE
.1 X 206.92 = 20.6 grams/litre to make a .1 solution
I scaled it down to 5 grams for 250 mililiters
I have a gunpowder scale and graduated beakers but it didnt worh.
I used the bottle of .1 solution i have in my inventory and it worked fine.
Can any one find the time to check my wprk and tell me what i did wrong.
I do it to learn no other reason.
I never had chemistry in school
