what is the solubility of Pb(NO3)2, PbCl2, PbCrO4, and PbS from highest to lowest
and the Ksp as well
im so lost! :(
Pb(NO3)2 is relatively soluble in water and will have the highest solubility of the four listed.
For the others, look the Ksp. It is strictly correct to compare Ksp but in this case it will work.
I should have said, "For the others, look UP the Ksp FOR EACH. It is NOT strictly correct to compare Ksp but in this case it will work.
To determine the solubility of various compounds, we can refer to solubility rules and use the concept of ionic compounds and their dissociation in water. Let's analyze each compound one by one:
1. Pb(NO3)2 (Lead(II) nitrate):
Lead(II) nitrate is a soluble compound. Most nitrate (NO3-) compounds are soluble, making Pb(NO3)2 soluble as well. The solubility of Pb(NO3)2 is high.
2. PbCl2 (Lead(II) chloride):
Lead(II) chloride is a sparingly soluble compound. Chloride compounds are usually soluble, except when combined with a few specific elements, such as Ag+ (silver), Hg2+ (mercury), and Pb2+ (lead). As a result, PbCl2 has low solubility.
3. PbCrO4 (Lead(II) chromate):
Lead(II) chromate is also a sparingly soluble compound. Chromate compounds are generally insoluble, except when combined with alkali metals and ammonium. Since PbCrO4 is not combined with alkali metals or ammonium, its solubility is low.
4. PbS (Lead(II) sulfide):
Lead(II) sulfide is an insoluble compound. Most sulfide compounds are insoluble, except when combined with alkali metals and ammonium. Since PbS does not fall under the exceptions, its solubility is very low.
Therefore, from highest to lowest solubility, we have: Pb(NO3)2 > PbCl2 > PbCrO4 > PbS.
