How can we determine the charge on the colloidal particles?
100 mL 0.2 M Mg(NO3)2 AND 100 mL 0.2M NaF ARE MIXED.WHAT IS THE CONCENTRATION LEFTOF Mg^2+ and F^- IN SOLUTION??? PLEASE GIVE DETAIL EXPLANATION
The Ksp for silver carbonate is 8.4 x 10¯12. The concentration of carbonate ions in a saturated solution is 1.28 x 10¯4 M. What is the concentration of silver ions?
If the equilibrium of a slightly soluble salt shift to the left due to common ion, then why and how the solubility decrease? please explain.
I have learnt that for a saturated solution the common ion effect affect the solubility. and for an unsaturated solution it has no effect . Is it true? then please explain why it has no effect in an unsaturated solution?

Due to common ion effect does the solubility always decrease? Can the common ion increase the solubility anyway? if not then why ?
