The enthalpy change for the reaction, AHr, is equal to : 3 points The enthalpy change for the reaction to form hydrated sodium thiosulfate crystals cannot be measured directly. The following Hess cycle can be used. ΔΗ, Na,5,9,(s) + 5H.0(l) → Na,5,9,5H,0(s) +aq ΔΗ, AH, tag Na 5,0, (aq) AH1 - AH2 ΔΗ1 + ΔΗ2 O -ΔΗ1 -ΔΗ2 -ΔΗ1 + ΔΗ2
