Since the salts are soluble, Ksp value is large number
So, Ksp is greater than 1
Delta G = -R*T*ln Ksp
Since Ksp is greater than 1, delta G is negative
Answer: greater than 1, negative

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. For ear (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. zinc sulfide 2. lead chloride A. CaCO3 B. Zn(CN)2 C. BaF2 D. Ag3PO4 Write the expression for K in terms of the...

Use the given K. values to predict which of the following salts is the most soluble, in terms of moles per liter, in pure water. (Hint: The size of Ksp tells us about solubility in general. The tutorial will explain the math but comparing the values for the general solubility is sufficient for these since they are all 1:2 ratios of ions.) Special note: mercury(I) ions forms a dimer and behaves like a polyatomic ion. So, Hg,X, breaks into Hg2+...
