Please suggest some salts of molybdenum (except sodium molybdate) which are soluble in water and do not hydrolyze.

Please suggest some inorganic salts of calcium which are soluble in water and do not hydrolyze or hydrolyze only slightly. I'm trying to modify a reported gelation procedure where CaCl2 is used, but the solution has a pH around 3.5 due to hydrolysis. I need an aqueous source of Ca2+ where the pH is closer to neutral.
