you are given the equation

Question

S2O3 + 2H --> S + SO2 + H2O

you mix 25 ml of HCl with a concentration of 2 mol/L
with 5 mL of Na2S2O3 with a
concentration of 0.3 mol/L.

what is the concentration of
S2O3 and H?

Answer 1

You REALLY should put charges on these equations. I spent 15 minutes trying to figure out what S2O3 was.

(S2O3^-2) = 0.3 x (5/20) =
(H^+) = 0.2 x (25/30) =
