Put 100 grams in a beaker and and around 500 mls of water until it dissolves, then top up the beaker to a liter. That is your 10% solution. The percentage solution is a ratio of the weight of the compound to the weight of the final solution.
sodium metabisulfite oxidizes best in an alkaline (basic solution). In low pH (2-3) the reaction occurs very slowly or not at all..
The chemical formula of sodium bicarbonate is NaHCO3. The chemical formula of sodium metabisulfite is Na2S2O5.

(x L)((12%) = (100 L)(2%)x = 16.7 liters
sodium metabisulfite known to be fungicidal when used alone at high concentrations. sodium metabisulfite has potential undesirable side-effects:1) sodium metabisulfite emits sulfur dioxide at acidic pHs creating a potentially toxic atmosphere for humans, they can contribute to acid rain development.2) Residues of sodium sulfite can remain on treated plants. Many people are allergic to sodium sulfite in foods so metabisulfite-containing fungicides should not be applied immediately before harvest.
The volume is 0,3 mL.

2NaHSO3 + Br2 + H2O = NaBr + NaOBr + SO2 + H3O+ I am not happy with this answer - you have a positive charge appearing from nowhere. Also NaHSO3 is sodium bisulfite the questioner asked for sodium metabisulfite which is Na2S2O5 . However, sodium metabisulfite in the presence of water does convert to sodium bisulfite Na2S2O5 + H2O = 2NaHSO3 2NaHSO3 + Br2 + H2O = 2NaBr + H2SO4 + H2SO3
