    COnductivity of a solution with Na2SO4 and NaHCO3?

    Does soemone know a way to calculate the conductivity in microSiemens/cm of such a solution? Medium: distilled water Concentrations are 0.01 mol/L Na2SO4 and 0.0022 mol/L NaHCO3. pH is 7.4. Also just hints are really appreciated! :)

    Enthalpy reaction of NaHCO3 and HCL

    Could someone help me with the last part of calculating the enthalpy? This is what I have so far A 100 cm3 of 2 mol dm-3 hydrochloric acid was poured into a polystyrene cup. 14 grams of sodium bicarbonate was added with. Initial temperature was 21.0 C and final temperature was 12.0 C. The...
