If 1.35 g of silver nitrate is dissolved in 115mL of water, and to this solution is added 5.00 mL of 1.45M hydrochloric acid resulting in the formation of a precipitant. Find the concentration of silver ions remaining in solution.
Describe how adding a solution of koh to the original sulfide precipitate results in the seperation of SN4+ ion from the other group II cation
calculate deltaH in kilojoules for the reaction, assuming that the heat capacity of the calorimeter is 776 j/celsius, that the specific heat of the final solution is the same as that of water(4.184J/G*C), and that the density of the solution is 1...
Titanium occurs in the magnetic mineral ilmenite (FeTiO3), which is often found mixed up with sand. The ilmenite can be separated from the sand with magnets. The titanium can then be extracted from the ilmenite by the following set of reactions
