To each digestion flask 200 mL aliquots of 10 different drinking water samples were added. Silver was extracted by a co-precipitation procedure and collected by filtration. The precipitate was digested in 200 μl hot concentrated nitric acid and diluted to 5 mL in a dilute phosphate solution. Standards were prepared according to the following table. The samples were analyzed by graphite furnace AAS. Calculate the concentration of silver in each sample. Are there any problems? How will you address each of the identified problems?
The addition of dimethylglyoxime, H2C4H602N2, to a solution containing nickel(Il) ion gives rise to a precipitate: Nickel dimethylglyoxime is a bulky precipitate that is inconvenient to manipulate in amounts greater than 135 mg. The amount of nickel in a type of permanent-magnet alloy ranges between 22% and 38%. Calculate the sample size that should not be exceeded when analyzing these alloys for nickel.

Use the following atomic masses (in g/mol):Mg = 24.31; O = 16; Ca = 40.08; C = 12.01; Na = 23; H = 1; N = 14.01; S = 32.06; Cl = 35.45; 2.) Limestone consists chiefly of mineral calcite (CaCO3). The carbonate content of 0.5413g of powdered limestone was measured by suspending the powder in water, adding 10mL of 1.392M HCl and heating to dissolve the solid and expel CO2. The excess acid required 39.96mL of 0.1004M NaOH for complete titration to a phenolphthalein end point. Find the % wt of calcite in limestone.
A sample of iron ore weighing 800 mg was treated with HNO3 , boiled to dryness and redissolved in dilute HCl. After filtration and removal of undissolved silica, the liquid was passed through a Walden reductor. The collected sample was titrated with 0.0210 M KMnO4 , requiring 12.0 mL to reach the end point. Calc %Fe (55.845) in the ore.
For the alloy Mg-45 wt% Pb alloy at 500 C, what is the weight percentage of Pb in liquid?
A titrimetric method for the determination of calcium in limestone was tested by analysis of an NIST limestone containing 30.15% CaO. The mean result of four analyses was 30.26% CaO, with a standard deviation of 0.085%. By pooling data from several analyses, it was established that s   = 0.094% CaO.a. Do the data indicate the presence of a systematic error at the 95% confidence level?b. Do the data indicate the presence of systematic error at the 95% confidence level if no pooled value for s was available?
Impure nickel, refined by smelting sulfide ores in a blast furnace, can be convertedinto metal from 99.90% to 99.99% purity by the Mond process. The primaryreaction involved in the Mond process is:Ni(s) + 4CO(g) ⇌ Ni(CO)4(g)In the second step of the Mond process, the gaseous Ni(CO)4 is isolated andheated to 227°C. The purpose of this step is to deposit as much nickel as possibleas pure solid (the reverse of the preceding reaction). Calculate the equilibriumconstant for the preceding reaction at 227°C.
