Question

For each of the salts on the left, match the salts on the right that can be compared directly, using Ksp values, to estimate solubilities. (If more than one salt on the right can be directly compared, include all the relevant salts by writing your answer as a string of characters without punctuation, e.g, ABC.) 1. iron(III) sulfide A. CaCO3 2. manganese(II) carbonate B. Ba3(PO4)2 C. Zn3(PO4)2 D. Co(OH)2 Write the expression for K in terms of the solubility, s, for each salt, when dissolved in water. iron(III) sulfide manganese(II) carbonate Ksp = Ksp = Note: Multiply out any number and put it first in the Ksp expression. Combine all exponents for s.

Step 1

iron(III) sulfide can be compared directly to zinc phosphate (Zn3(PO4)2) using Ksp values to estimate solubilities. The expression for Ksp for iron(III) sulfide is: Ksp = [Fe3+][S2-] Show more…

00:01 All right, so we are asked to match salts on the left.

00:04 One, we have iron 3 sulfide as fe2s3 and manganese carbonate.

00:13 All right, so first, let's establish what their ksp values are.

00:17 So fe2s3, when this ionizes, what you have is two moles of fe3 plus plus three moles of s2 minus, which means that if the solubility of this is s, this would be 2s and this would be 3s.

00:36 So the ksp is the concentration of fe2 plus squared times the concentration of fe3 plus squared, sorry, and s2 minus cubed.

00:51 So this becomes 2s all squared times 3s all cubed.

01:00 And that's 108 s raised to the power of five.

01:05 So we want to compare the two salts that have similar, while that of manganese carbonate, and then simply mn2 plus plus co3 2 minus.

01:23 So the ksp would be s squared.

01:28 Ok, so those are the ksp expressions.

01:31 So let's compare them to the salts that we're given.

01:34 A, we had calcium carbonate.

01:37 B, we had barium phosphate, ba3po4 bracket.

01:46 C, we had zinc similar.

01:52 And then d, we had the cobalt 2 -hydroxide.

01:55 So quite clearly, you can see that first, this and this will match because calcium carbonate has the same, right? when it ionizes, co2 plus plus co3 2 minus...
