If the AHsolution, KI = 15 kJ/mol, then calculate the lattice energy for potassium iodide using the data from a standard reference table shown here.
DeltaHhydration
K+ -335kJ/mol
I- -293kJ/mol

What is the total reduction potential of a cell in which potassium (k) is reduced and copper (cu) is oxidized? a. 2.59 v b. 3.27 v c. -3.27 v d.-2.59 v

7. what temperature is need to just dissolve 50 g of nh4cl in 75 g of water? '

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.
