A compound ( M. Wt =180) absorbs 65% of the radiation at certain wavelength in a 1.00 cm cell at a concentration of 15 ug/ml. Calculate its molar absorptivity.

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.

What is an example of a physical property?
