Magnesium Chloride is available as magnesium chloride hexahydrate in an injectable solution that supplies 1.97 mEq of magnesium per milliliter. What is the percent strength of magnesium chloride hexahydrate in this solution?
What is the concentration of ions in the soil solution after fertilizer application? Suppose that 122 pounds of K+ were applied per acre, then a gentle rain soaked the top 10 inches of soil to field capacity, which for the given soil was about 16% water by volume. If the K+ was applied as KCl, it is plausible that it all dissolved and distributed relatively uniformly with the infiltrating water. If so, then what was the K+ concentration in the soil solution in mol K+/L solution? Note that the volume can be computed like we do for an acre-furrow-slice (AFS), as area times depth. This is going to be a relatively small number, so please report your answer in mol K+/L solution to at least 5 decimal places.
In the laboratory, a student was tasked to prepare a stock solution of HCl for titration. The available analytical grade HCl solution in the stock room was labelled 35% w/v HCl. The student proceeded to prepare the stock solution by mixing 10mL of the HCl solution with 490mL of analytical grade water. Then, the solution was further diluted by adding 5mL, since the total volume of the solution did not reach the 500mL etched mark on the volumetric flask. To prepare the titrant, the student mixed 10mL of the stock solution, then added 40mL of analytical grade water. The titrant was subsequently used to determine the concentration of two titrand. *Use the table as a reference 1.

A sample containing chlorophenol, C6H4ClOH, was analysed by gravimetric analysis. A 0.783-g of this sample goes through a chemical process allowing the chlorine in the chlorophenol to precipitate as silver chloride, weighing 0.271 g. Calculate the % (wt/wt) of the chlorophenol in the sample, assuming that chlorophenol is the only source of chlorine in the sample. Provide your answer to two decimal places and without units. Avoid using scientific notation.
If a dilute H2 SO4 solution is electrolyzed with copper electrodes, the most likely electrode reactions are 2H ^ + + 2e- = H2 (g) at the cathode and 2Cu (s) + H2O = Cu2O (s) + 2H ^ + + 2e- at the anode. If we observe the formation of 27.4 cm3 of moist hydrogen (751 barometric torrs, 23.3 ° C) at the cathode, what change in weight will there be simultaneously at the anode? Data: Pv H2O 23.3 ° C = 22 torr.Atomic mass: Cu (65); O (16); H (1)
Zinc may be directly leached from zinc-lead sulphide concentrates by reaction with sulphuricPbS(s) + H2SO4 + 1 O2(g) → PbSO4(solid) + SÂ° + H2O 21ZnS(s) + H2SO4 + 2 O2(g) → ZnSO4(aq) + SÂ° + H2Oacid and oxygen. In addition, lead sulphide will be oxidized to give insoluble lead sulphate:Assume that a plant is to treat 400 t/day of concentrate containing 20.0 weight % Zn as ZnS and 110.0 weight % Pb and PbS. The concentrate and leach solution enters the leaching vessel at 32.0% solids. During the leach, 85.0% of the zinc is extracted and all the lead sulphide is oxidized.

A solution containing 0.402 49 g of CoCl2 ? xH2O (a solid with an unknown number of waters of hydration) was exhaustively electrolyzed to deposit 0.099 37 g of metallic cobalt on a platinum cathode by the reaction Co21 1 2e2¡Co1s2. Calculate the number of moles of water per mole of cobalt in thereagent. A good approach is to find moles of Co, moles of CoCl2, mass of CoCl2, and, by difference, mass of H2O in the sample.
