To a 200.0 mL volumetric flask are added 1.00 mL volumes of three solutions: 0.0100 M AgNO_3, 0.140 M NaBr, and 0.100 M NaCN. The mixture is diluted with deionized water to the mark and shaken vigorously. What mass of AgBr would precipitate from this mixture?
To a 250.0 mL volumetric flask are added 1.00 mL volumes of three solutions: 0.0100 M AgNO3, 0.245 M NaBr, and 0.100 M NaCN. The mixture is diluted with deionized water to the mark and shaken vigorously What mass of AgBr would precipitate from this mixture? (Hint: The Ksp of AgBr is 5.4 x 10-13 and the Ky of Ag(CN)2-is 1.0 × 1021) Number g AgBr
A standard iron solution was prepared by dissolving 0.0100 g of pure iron in acid then transferring to a 50.00 mL volumetric flask with orthophenanthroline as a complexing agent. At a wavelength of 540 nm, the absorbance of the standard was 0.239 in a 1.00 cm cuvette. A 0.149 g sample of an iron ore was crushed and digested in 5 mL of concentrated acid. The digested sample was then transferred to a 10.00 mL volumetric flask and diluted to...
You are provided with a 250 mL volumetric flask, deionized water, and solid NaOH. How much NaOH should be weighed out in order to make 250. mL of 0.100 M solution?
A buffer is prepared by mixing 200.0 mL of 0.1500 M NaOH with 200.0 mL of 0.200 M CH3CO2H in a 1-L volumetric flask and then diluted to volume with distilled deionized water. Calculate the pH of the buffer. Ka = 1.75 x 10-5
A 2.0 M stock solution of Tylenol was diluted as follows: 15.000 mL of stock solution was added to a 250-ml volumetric flask. Water was added to the flask until the solution's meniscus was at the line on the neck of the flask. 5.000 mL of solution from the 250-ml volumetric flask was added to a 100-ml volumetric flask. Water was added to the flask until the solution's meniscus was at the line on the neck of the flask. Calculate...
b) In this experiment an aspirin ta and dissolved in 10 mL of 1.0M Na mark with deionized water. Using a into a 100-mL volumetric flask and make a diluted aspirin solution'. ent an aspirin tablet was placed in a 250-ml volumetric flask 10 mL of 1.OM NaOH solution, the flask was then filled to the zed water. Using a pipette, 5.0 mL of this solution was added IL Volumetric flask and diluted to the mark with FeCl solution to...
Analyzing various samples of bottled water, tap water, and 0.01200 M MgSO4*7H2O. Given that we will be using EDTA of conversations 0.0100 M, a) What volume of the stock solution sample would you have to analyze if you wouldn’t want to spend more than 10 mL of the EDTA? b) Suppose you dilute your Mg+2 stock by measuring 10 mL in a graduated cylinder and using deionized water up to the 100 mL mark in a volumetric flask. What volume...
10.4 Calculate the mL of 0.100 M EDTA needed to titrate 100.0 mL of a 0.0100 M solution of these metal ions. (a) TI (b) Pb (10.0 mL) (c) Fe+
A buffer is prepared by mixing 200.0 mL of 0.1500 M NaOH with 200.0 mL of 0.200 M Benzoic Acid (a monoprotic carboxylic acid) in a 1-L volumetric flask and then diluted to volume with distilled deionized water. Calculate the pH of the buffer. Ka= 6.28 × 10−5and pKa= 4.01. A. 3.53 B. 4.01 C. 4.49 D. 7.00 E. 11.49
