- You choose to investigate some of the solubility guidelinesfor two ions , the chromate ion(CrO4)-2 and the oxalate ion (C2O4) - 2. You are given 0.01 Msolutions (A, B, C, D) of four water-soluble salts: When these solutions are mixed, the following observationsare made as given in table: (a) Write a net ionic equation for the reaction that occurs ineach of the experiments. (b) Identify the precipitate formed,if any, in each of the experiments.Suppose 234.3 mg of PbCl2 was added to 16.0 mL of water in a flask, and the solution was allowed to reach equilibrium at 21.0 oC. Some solute remained at the bottom of the flask after equilibrium, and the solution was filtered to collect the remaining PbCl2, which had a mass of 91.6 mg . What is the solubility of PbCl2 (in g/L)? -Express the concentration in grams per liter to three significant figures.A 0.4723-g sample of primary-standard-grade Na2CO3 required 34.78 mL of an H2SO4 solution to reach the end point in the reaction CO32- + 2H+ → H2O + CO2 (g) What is the molar concentration of the H2SO4?
- A 0.4723 g sample of primary-standard-grade Na2CO3 required 34.78 mL of an H2SO4 solution to reach the end point in the reaction CO3^(2-) + 2H^(+) → H2O + CO2(g) What is the molar concentration of H2SO4?A student weighs out 1.118g of impure HPT, dissolves the sample in deionized water and tirates it with 0.1001M of NaOH solution. If the titration requires 2710mL of the NaOH solution, and none of the impurities react with NaOH, what is the percent KHP in the sample? I'm confused why none of the impurities would react. I multipled 0.1001M by 2.71L and got 0.2172M of NaOH. As it's 1:1 ratio, shouldn't the point of equivalence be 0.2712 mol of KHP? But I do not have the volume of KHP so how can I calculate the molarity with only grams (which can be turned into mol) and no volume?I need help calculating solubility for this question. thank you C. Calcium Fluoride, CaF2 (aka, Fluorite), in a solution containing 19 mg/L of LiF (aka, Griceite), with all of the LiF being dissolved into solution. Please assume that LiF dissolves such that [Li] = [F] = 7.33 x 10-4 m. After adding CaF2 to the solution and allowing it to dissolve, what are final values of [Ca], [Li] and [F]? Note: you are given the concentrations of [Li] and [F] that result from dissolving LiF. No solubility calculation is required for dissolving LiF; just use the concentration given above. Steps: - First, write the stoichiometric equation for dissolution of CaF2, with the solid on the left and the two ions in solution on the right, separated by a "two-way" arrow. Hint: when CaF2 dissolves, you get 2 moles of F for every 1 mole of Ca. - Second, set up a law of mass action equation for dissolution of CaF2. There is a common ion effect for F, so if [Ca] = x, then [F]= 2x + [FLiF], where [FLiF] is from…
- Mg(OH)2 is a sparingly soluble salt with a solubility product, Ksp, of 5.61×10−11. It is used to control the pH and provide nutrients in the biological (microbial) treatment of municipal wastewater streams.

Question: Calculate the percent by mass of Vitamin C in the Real Lemon SamplePerform these calculations for nickel(II) carbonate. (a) With what volume of water must a precipitate containing NiCO3 be washed to dissolve 0.100 g of this compound? Assume that the wash water becomes saturated with NiCO3(Ksp=1.36107). (b) If the NiCO3 were a contaminant in a sample of COCO3(Ksp=1.01012), what mass of COCO3 would have been lost? Keep in mind that both NiCO3 and COCO3 dissolve in the same solution.
