A mixture contains Mg(NO3)2 and KBr. A 1.85 g sample of this mixture is dissolved in water and an excess of NaOH is added, producing a precipitate of Mg(OH)₂. The precipitate is filtered, dried, and weighed. The mass of the precipitate is 0.335 g. What is the mass percent of Mg(NO3)2 in the original mixture?

Excess Na2SO4(aq) is added to a 4.41×102 mL sample of industrial waste containing Ba2+ ions. If 55.5 g of BaSO4(s) are precipitated from the reaction, what was the molar concentration of Ba2+ in the original sample?
A 1.50 g sample of KCl is dissolved in 36.0 mL of water. The resulting solution is then added to 32.0 mL of a 0.470 M CaCl2 (aq) solution. Assuming that the volumes are additive, calculate the concentrations of each ion present in the final solution. Concentration of K* ions = M Concentration of Ca2+ ions = M Concentration of Cl ions = M
In the laboratory you are given the task of separating Ca2+ and Co2+ ions in aqueous solution.For each reagent listed below indicate if it can be used to separate the ions.

What is the percent composition by mass of NaBr and CaBr2 in the sample?
Excess Na2SO4(aq) is added to a 4.41×102 mL sample of industrial waste containing Ba2+ ions. If 55.5 g of BaSO4(s) are precipitated from the reaction, what was the molar concentration of Ba2+ in the original sample?
A sodium sulfate solution is added to a 25.0 mL sample of a solution containing Ba2+ ions until no more precipitate formed. The precipitate (BaSO4) is collected, dried, and weighed. If 1.59 g of the precipitate are obtained, what is the concentration (in M) of Ba2+ ions in the 25.0 mL sample? Your answer should have 3 sig. figs. Molar Masses: (Na2SO4: 142.05 g/mol) (Ba2+: 137.3 g/mol) (BaSO4: 233.37 g/mol)
The concentration of a certain sodium hydroxide solution was determined by using the solution to titrate a sample of potassium hydrogen phthalate (abbreviated as KHP). KHP is an acid with one acidic hydrogen and a molar mass of 204.22 g/mol. In the titration, 28.16 mL of the sodium hydroxide solution was required to react with 0.5040 g KHP.
