Answer:
Adding NaCl to a saturated PbCl2 solution will decrease the Pb2+ concentration.
Explanation:
If a solution is saturated this means it cannot dissolve more material.
PbCl2 ⇆ Pb2+ + 2Cl-
Adding more Cl- in the solution is the same thing as trying to dissolve more of the material. In the solution, the concentration of Cl- will increase.
In order for the Ksp to maintain a constant value, the concentration of Pb2+ must decrease if the concentration of Cl- is increased.
Adding NaCl to a saturated PbCl2 solution will decrease the Pb2+ concentration.
Covalent bonds but not ionic
Answer:
you tilt the cylinder at a slight angle so that the metal slides down the sides, rather than drops all it`s weight to the bottom
