A solution is prepared by dissolving 2.95 g Co2(SO4)3 in enough water to make 1.00 L of red solution; the red color is due to the presence of the cobalt ions. To this solution was added 1.52 g of magnesium powder. A redox reaction occurred, in which the magnesium atoms lose all of their valence electrons and the red color of the solution fades. (a) Write the total reaction that occurs and the net ionic equation for the redox process. (Assume that one of the products of the redox reaction is a metal.) (b) Calculate the initial concentration of cobalt ions, the final concentration of cobalt ions, and the final concentration of magnesium ions.
3. Assume that 2.1429 g of Cr(NO3)3 is dissolved in enough water to make 50.00 mL of solution. (a) What is the molarity of Cr(NO3)3? (b) What is the molarity of the chromium(III) cation? (c) What is the molarity of the nitrate anion? The molar mass of Cr(NO3)3 is 238.011 g/mol.

0.9545 g of calcium nitrate salt, Ca (NO3) 2, is weighed, dissolved in concentrated HCl solution and added to 500 ml with water. It is diluted, 100 ml sample taken here is precipitated as CaC2O4, burned in the ash furnace and It is converted to CaCO3 and then to CaO. Since it comes to 0.2500 g when weighed, the amount of Ca in the sample and calculate its% (Ca: 40 g / mol, O: 16 g / mol)
Suppose that a solution prepared by dissolving 0.554 g of MgCl2 in about 30 mL of water is mixed with a solution that contains excess K2CO3 dissolved in about 30 mL of water. What is the theoretical yield (in grams) of MgCO3 in the precipitation reaction that occurs?
A titration is performed to determine the amount of sulfuric acid, H2SO4,, in a 6.5mL sample taken from a car battery. About 50mL of water is added to the sample, and then it is titrated with 43.37mL of standard 0.5824 molar NaOH solution. How many moles of sulfuric acid are present in the original sample?

The zinc content of a 1.55 g ore sample was determined by dissolving the ore in HCl, which reacts with the zinc. The excess HCl is then neutralized with with NaOH. The reaction of HClHCl with Zn is shown. Zn(s)+2HCl(aq)⟶ZnCl2⁢(aq)+H2⁡(g) The ore was dissolved in 150 mL of 0.600 M HCl and the resulting solution was diluted to a total volume of 300 mL. A 20.0 mL aliquot of the final solution required 8.92 mL of 0.548 NaOH to neutralize the excess HCl. What is the mass percentage (%w/w) of Zn in the ore sample?
