The Handbook of Chemistry and Physics (http://openstaxcollege.org/l/16Handbook) gives solubilities of the following compounds in grams per 100 mL of water. Because these compounds are only slightly soluble, assume that the volume does not change on dissolution and calculate the solubility product for each. (a) BaSeO4, 0.0118 g/100 mL. (b) Ba(BrO3)2H2O, 0.30 g/100 mL. (c) NH4MgAsO46H2O, 0.033 g/100 mL. (d) La2(MoO4)3, 0.00179 g/100 mL
FeCl3 and MgCl2 solution was prepared by dissolving FeCl3 (AR) and MgCl2 (AR) in distilled water. Secondly, under rapid stirring, NaHCO3 powder was slowly added to the above solution to the desired basicity (B = 1) which had been proved to be the optimal B for turbidity removal. Thirdly, Na2HPO4 (AR) was added to the PFMC solution as a stabilizer ([Na2HPO4]/([Fe] + [Mg]) = 0.08). i. The the chemical equation of the Synthesis. ii How much weight need to put NaHCO3 above solution the desired basicity (B=1) iii.

It is required to know the concentration of an aqueous solution of H2SO4 that appeared in the laboratoryChemistry III and it's unlabeled. To this end, a student of analytical chemistry carried out the followingProcedure: He took 5.00 mL of a fresh and standardized solution of 0.525M NaOH and brought them to a250.0 mL balloon to be completed with distilled water. Subsequently, he poured 15.00 mL of the solutionH2SO4 of unknown concentration in an Erlenmeyer flask and added 2 drops of phenolphthalein.Using a burette filled with the last NaOH solution, he noticed that when adding 39.40 mL of the hydroxidethe Erlenmeyer solution reached a faint but permanent pink. With the above dataDetermine the concentration and pH of the H2SO4 solution.
