Write the symbol (and charge for the ion that will be used to precipitate the sulfate
The precipitate did not dissolve because sulfate ion is too weak a base. The amount of sulfate ion that reacts with the hydronium ion is too small to cause a shift in the equilibrium sufficient to dissolve a signiticant amount of the insoluble sulfate. In general, the anion of a precipitate must be a stronger base than fluoride ion in order for the precipitate to be dissolved by the addition of a strong acid. After the reactions with barium ion,...
If 56.8 mL of BaCl2 solution is needed to precipitate all the sulfate ion in a 752 mg sample of Na2SO4, what is the molarity of the solution? Express the molarity to three significant digits.

Ba(NO3)2 (b 3) For each combination of ionic compounds shown below, indicate whether a precipitate will form or not. If so, write the formula of the precipitate. Reaction Precipitate YES OR NO Formula of the precipitate FeCl2(aq) + Na2S(aq.) Pb(NO3)2(aq.) + NaCl(aq.) Juf A I :1 in 250 ml colution le
How many mL of 0.250 M BaCl2 would you need to precipitate all the sulfate ion present in 38.1 mL of 0.197 M H2SO4 solution? What is the concentration (M) of the chloride ion remaining in the resulting solution?
Why would magnesium sulfate is give the same result (white precipitate) in the Phosphate ion test as zinc acetate? The control procedure was 2mL of .1M zinc acetate with 2 mL sodium phosphate tribasic in a test tube. Yields a white suspended precipitate immediately. The experiment was a mixture of the same sodium solution and 2mL of unknown liquid this yielded the same result immediately. I then tried to confirm my guess of the unknown liquid as magnesium sulfate by...

How many grams Ba(NO3)2 of are required to precipitate all the sulfate ion present in 15.3 mL of 0.143 M H2SO4 solution? Ba(NO3)2 + H2SO4 --> BaSO4 + 2HNO3

POSTLABORATORY ASSIGNMENT 1. An iodide/chloride/sulfate unknown solution gave a yellow precipitate with AgNO The supernate did not react with Ba(NO)). The yellow precipitate did not dissolve in NH, H,O. After centrifuging the supernate was acidified with HNO, and gave a white precipitate. State the ion(s) present in the unknown solution. An iodide/chloride/sulfate unknown solution plus AgNO, gave no reaction. The solution was treated with Ba(NOs)2 and produced a white precipitate. State the ion(s) present in the unknown solution....
