Let's determine if a precipitate of lead hydroxide will form.
00:07
We're starting with equilibrium, pb 2 +, edta 4 minus.
00:18
In equilibrium, this will produce pb, edta 2 minus.
00:31
Set up an ice table.
00:33
Initially, pb2 plus is 0 .0 molar.
00:37
Edta, 0 .050 molar.
00:40
This be 0, ang, minus 0 .010, minus 0 .010, and plus 01010.
00:54
This would be x.
00:57
040 plus x, and 010 minus x.
01:09
Equilibrium constant here, is equal to the concentration, pb, ed, ta, 2, minus.
01:22
Concentration of pb2 plus, concentration of edta4 minus.
01:29
We're given the equilibrium constant here is 1 .1 times 10 to the 18.
01:38
0 .1 minus x...
