A chemist needs to create a series of standard Cu2+(aq) solutions for an absorbance experiment. For the first standard, he uses a pipet to transfer 25.0025.00 mL of a 2.552.55 M Cu2+(aq) stock solution to a 500.0 volumetric flask, and he adds enough water to dilute to the mark. He then uses a second pipet to transfer 10.00 mL of the second solution to a 100.0 mL volumetric flask, and he adds enough water to dilute to the mark. Calculate the concentration of the Cu2+(aq) solution in the 100.0 mL volumetric flask.

Andrew dissolved 10.00 grams of an iron ore sample in 5.00 L of acid to produce a stock solution. Josh ran a trial of the analytical procedure on the stock solution, but found the solution was too concentrated to be used. So Josh prepared a 1:250 dilution of the sample solution, and, after running the analytical procedure successfully, found the solution contained 1.62 x 10-5 mol/L Fe2+ (aq). What is the mass of iron in the meteorite sample?
Potassium permanganate in acidic solution is used to titrate a solution of copper(I) ions, with which it reacts according to MnO4-(aq) + 5Cu+(aq)+8H3O+(aq)Mn2+(aq) + 5Cu2+(aq)+12H2O(l) A potassium permanganate solution is prepared by dissolving 23.14 g of KMnO4 in water and diluting to a total volume of 1.000 L. A total of 15.61 mL of this solution is required to reach the endpoint in a titration of a 200.0-mL sample containing Cu+(aq). Determine the concentration of Cu+ in the original solution.
A 1.6 g sample of a compound is transfered to a 100 mL volumetric flask, filled to the mark with distilled water, and thoroughly mixed. Twenty five milliters of this solution is drawn from the flask using a volumetric pipet, transfered to another 100 mL volumetric flask, and filled to the mark and mixed. The grams of compound in the second volumetric flask is: A. 1.6 B. 1.2 C. 0.80 D. 0.40
Tartaric acid, H2C4H4O6, is a diprotic acid that naturally occurs in the production of apple wine. Emma was tasked to find out the acid content in a 50.0 mL wine sample by titrating it with a standardized solution of NaOH. She was able to establish the working concentration of the NaOH solution by using 17.61 mL of NaOH to titrate a primary standard of KHP that weighed 1.501 g. The grams and %w/w of Tartaric acid present in the 50.0 mL wine sample were then determined by titrating a 12.50 mL aliquot using 21.78 mL of the standardized NaOH solution. H2C4H4O6 (aq) + 2NaOH (aq) ↔ Na2C4H4O6 (aq) + 2H2O (l) Assume that the density of the wine sample is 1.000 g/mL MM of KHP = 204.22 g/mol MM of H2C4H4O6 = 150.087 g/mol What is the molar concentration of the prepared NaOH solution?…
A student determined fluoride in a toothpaste sample using ion chromatography. A toothpaste sample of mass 0.100 g was dissolved in type I water and then quantitatively filtered through a Whatman #1 filter paper into a clean 100 ml volumetric flask. The flask was then made up to volume with type I water and mixed thoroughly.A portion of the solution was filtered through a 0.45 um filter into a sample vial for analysis. Analysis of the sample gave a fluoride concentration of 1.60 mg/l Calculate the % w/w fluoride in the original toothpaste sample. (Give your answer to 3 decimal places please)

Solutions of cyanide salts are still widely used in the extraction of gold metal from its ores. It is thereforenecessary to regularly monitor the quality of the reagents used to make such solutions.The purity of a sample of solid potassium cyanide is determined as follows: 5.00 g of the impure potassium cyanide is weighed off, and quantitatively transferred into a100.00 mL volumetric flask, dissolved and made up to the mark. A 10.00 mL portion of this solution is pipetted into a conical flask, and titrated with a 0.200 MKMnO4 solution. The endpoint of the titration is determined when the colourless solution in the conical flask turns abright pink due to the presence of excess permanganate ions. The average titration value is 20.69 mL of the KMnO4 solution.The reaction stoichiometry is as follows: 2KMno4(aq) + 3KCN(aq) + H2O(l) → 2MnO2(s) +3KOCN(aq) + 2KOH(aq) ૝1.1 Determine the percentage purity of the potassium cyanide.
