2 ml of 1M HCl

0 ml of H2O
3ml of .3M Na2S2O3
How do I find the initial and final concentrations of both HCl and Na2S2O3?

1 answer

The initial concentration of HCl is 1 M.
The initial concentration of sodium thiosulfate is 0.3 M.
The final concentration of HCl is the initial times 2÷5. The final concentration of sodium thiosulfate is the initial times 0.3÷5.
