Do only chemical reactions get colder/hotter?
What is happening when potassium chloride dissolves?
• What do we think is happening when we put potassium chloride in
water? Is it dissolving?
What does dissolving even mean?
Is this phenomenon similar to or different from the chemical reactions
we have already seen?
• Is this a physical change or a chemical reaction? What evidence would
we need to collect to be able to know if it was one or the other?

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.

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
