Determine whether a precipitate will form when 200 ml of 1.5 x 10^-3 m kcl is mixed with 300 ml of 2.0 x 10-7 m pb(no3)2 ? ksp pbcl2 = 1.7 x 10-

I.P << Ksp ⇒ precipitate will form when mixing these two substances in those quantities and concentrations

Explanation:

∴  Ksp PbCl2 = 1.7 E-5 = [ Cl- ]² * [ Pb2+ ]

⇒ I.P = [ Pb2+ ] * 2[ Cl- ]

∴ [ Pb2+ ] = ((2.0 E-7)*(0.300) / 0.5) = 1.2 E-7 M

∴ [ Cl- ] =((1.5 E-3)*(0.200) / 0.5) = 6 E-4 M

⇒ I.P = ( 1.2 E-7 ) * (6 E-4 ) = 7.2 E-11

∴ I.P << Ksp ⇒ precipitate formation

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

the answer is na (sodium)
