Construct a neat and compact table, including title and footnotes if required, to summarise the following information taken from rough notes: 'Acid A was titrated by four analysts and the following end points were obtained: 20.2mL, 20mL, 21mL and 20.8mL, the conductivities were also measured as 13, 13.6 13.8 and 14.2 micro-siemens respectively. The base used for the titration was 0.1 M sodium hydroxide. Acid B was titrated by four analysts and the following end points were obtained 210.2mL, 200mL, 211mL and 206.8mL, the conductivities were also measured as 12, 12.6 13.0 and 12.2 micro-siemens respectively. The base used for the titration was 0.1 M potassium hydroxide.?
Calculate pCu2+ at each of the following points in the titration of 50.0 mL of 0.001 M Cu 2+ with 0.001 M EDTA at pH 11.00 in a solution whose NH3 concentration is somehow fixed at 0.100 M:
A 100.0-mL sample of 0.10 M NH3 is titrated with 0.10 M HNO3. What is the pH of the solution after 100.00 mL of acid have been added to the ammonia solution?Kb = 1.8 × 10-5.
What is the balanced chemical reactions that takes place when h2o2, concentrated h2so4, and Cu(s) is placed in solution. One of the byproducts should be copper sulfate (CuSO4) and there is some gas evolution during the reaction.
What is the pH of a solution obtained by dissolving two extra-strength aspirin tablets, containing 500 mg of acetylsalicylic acid each, in 300 {mL} of water
Assuming that the smallest measurable wavelength in an experiment is 0.330 fm (femtometers), what is the maximum mass of an object traveling at 213 m·s-1 for which the de Broglie wavelength is observable
what is the [OH-] in a solution that has a pOH of 2.70? Use E notation with 3 significant figures.
In air and according to Stokes Law, the settling rate of particles is proprotional to the squares of their diameters, if they have the same densities
Suppose that the microwave radiation has a wavelength of 11.2cm . How many photons are required to heat 295mL of coffee from 25.0C to 62.0C
The use of the British thermal unit (Btu) is common in much engineering work. A Btu is the amount of heat required to raise the temperature of 1 lb of water by 1 degree Farenheit.
if you take a 12.5 mL portion of the stock solution and dilute it to a total volume of 0.600L what will be the concentration of the final solution?
A solution is prepared by dissolving 2.33g of C60 in 100.0g of toluene. Given that the vapor pressure of pure toluene is 5.00kPa at 30C what is the vapor pressure of toluene in the solution.
Nitric acid is purchased in a concentrated form that is 70.3% by mass and has a density of 1.41 g/mL. Describe exactly how you would prepare 1.15L of 0.100 M solution
