d) Cu I\n\nChromic and phosphoric acid are polyprotic acids and the salts will show a decreasing solubility with increasing pH as the higher pH favours the formation of chromate and phosphate.\n\nHydroIodic acid is a strong acid and is fully dissociated and the the amount of iodide formed depends on concentration and not pH. Thus CuI solubility will show no dependence on pH.

The question makes no sense.  A single, isolated anion has no pH value.  pH refers to the H+ concentration in aqueous solutions.

A property of soluble materials is their "heat of solution", which can be positive or negative. Adding calcium chloride or sulfuric acid to water, for example, heats the solution a lot. Ammonium chloride cools the resulting solution. See the references below for a fuller explanation.

The compounds have a high lattice enthalpy, thus much energy is required to break to ions up in solution. The also have very low solubility products, that is the product of the compounds ions in a saturated solution.

2 - Potassium Chloride\n\nIt has, by far, the weakest covalency of all those listed, and therefore breaks apart most readily.
