H g X 2 I X 2 ( s) H g X 2 X 2 + ( a q) + 2 I X − ( a q) Here is what I think I need in order to solve the question: Δ G = − R T ln ( K) where K will be the solubility constant.

Feb 26, 2021 · Both chlorides form multiple hydrates, stable at different humidity or temperature conditions. 35 mol L ⁻¹ as the heat exchange fluid entered the formation and within the. fc-falcon">has given an equal amount of heat to the reaction or process.

The heat exchange measured for the reaction was 1249 J. .

Relative Apparent Molal Enthalpy The results of measurements of the intermediate enthalpy of dilu- tion, AHdil(mi ---> mf), and the related relative apparent molai enthalpy L~ of MgCI2 solutions are given in Table I, where mi and mf are the in- itial and final molalities, and n~/n2 is the mole ratio water/MgCl2.
