The following equation is given:

S2O3 -2 + 2H +1 ---> S + SO2 + H2O

[HCl] = 2 mol/L
[Na2S2O3]= 0.3 mol/L

what is the concentration (mol/L) of H+ if you were to add:

a) 20 mL of HCL with 5 mL Na2S2O3 & with 5 mL H2O

b) 15 mL of HCl with 5 mL Na2S2O3 & 10 mL H2O

c) 7.50 mL of HCl with 5 mL Na2S2O3 & 17.50 mL H2O

d) 5 mL of HCl with 5 mL Na2S2O3 & 20 mL H2O
