Solubility of group 2 hydroxides
enthalpy of lattice and enthalpy of hydration both become less exothermic down the group
enthalpy of lattice changes faster
the enthalpy of solution becomes more exothermic
solution = hydration - lattice energy
why you can see different colors from different compounds
change in E value is different
different wavelengths of visible light absorbed/ different complimentary color seen
why you can see colors from compoounds
d-d splitting occurs
electron is excited/promoted to higher energy level
wavelengths of visible light absorbed and complimentary color seen
solubility of group 2 sulfates
same as hydroxides but enthalpy of hydration decreases faster than lattice enthalpy
more positive means less soluble (enthalpy of solution)
