e. larger molecules
the water for the pan is not saturated with CO2. Will the reported percent CaCO3 in the original sample be too high, too low, or unaffected? Explain
A 50.00 ml sample of water was treated as above and the I2 titrated with 0.01136 M Na2S2O3, of which 8.11 ml were required to reach the end point. Determine the concentration of the dissolved O2 in M (moles/L) and ppm (mg/L).
