You were calculating the concentration of EDTA (MW 372.24 g/mol; Q = 98.45%). You weighed out 8.6731 g of dried EDTA into a 450.13 mL clean volumetric flask. You showed your lab instructor your calculated EDTA concentration of (no units in standard notation with proper number of significant figures) A M. You prepared your limestone sample (1.7737 g) by dissolving it in HCl, gently heating and then filling to the line in the 450.13 mL volumetric flask. You lab partner used a 12.55 mL volumetric pipette for the limestone sample, and from the titration you recorded 25.60 mL (wine colour), 25.63 mL (purple colour). 25.67 mL (blue colour), 25.72 mL (blue colour). The P/F ratio for this calculation is (in standard notation and to the proper number of significant figures) A/ and the % Mg in the limestone sample is (answer in standard notation with no units to the proper %

Predict the products and balance the following equation. Reduce the coefficients to the smallest whole number ratio, and enter a 1 if the coefficient is a 1. Write the chemical symbol followed by a number, with no spaces. For example, water would be H2O. KOH(aq) + H2SO4(aq) → (l) + (aq)
A quantitative analysis for ethanol, C2H60, is accomplished by a redox back titration. Ethanol is oxidized to acetic acid, C2H402, using excess dichromate, 3+ Cr207 2-, which is reduced to Cr3*. The excess dichromate is titrated with Fe2*, giving C and Fe+ as products. In a typical analysis, a 5.00-mL sample of a brandy is diluted to 500 mL in a volumetric flask. A 10.00-mL sample is taken and the ethanol is removed by distillation and collected in 50.00 mL of an 2- acidified solution of 0.0200 M K2Cr207. Titration of the unreacted Cr207 requires 21.48 mL of 0.1014 M Fe2*. Calculate the %w/v ethanol in the brandy. Which is the titrant in this problem? C2H402 Fe2+ C2H60 O Cr207 2-

A 75.0 mL solution of potassium iodate (KIO3, 214.0 g/mol, 98%) was treated with KI and H2SO4 and then titrated with sodium thiosulfate (Na2S2O3, 158.1 g/mol). The titration required 5.00 mL of the titrant. If the solution contained 0.0325 g of the primary standard, what is the concentration of the titrant?
An iron ore was analyzed by dissolving a 2.9912-g sample in concentrated HCl. The resulting solution was diluted with water, and the iron(III) was precipitated as the hydrous oxide Fe203-xH20 by the addition of NH3. After filtration and washing, the residue was ignited at a high temperature to give 0.8394 g of pure Fe203 (159.69 g/mol). How many grams of Fe (55.847 g/mol) are there in the iron ore sample? 0.2936 g Fe 0.5871 g Fe (C) 0.1468 g Fe D) 0.7739 g Fe
Fe in ore can be analyzed by oxidizing Fe to Fe2+ then titrating Fe2+with K2Cr2O7 . See equation below. K2Cr2O7(aq) + 6Fe2+(aq) + 14H+(aq) → 2Cr3+(aq) + 2K+(aq) + 6Fe3+(aq) + 7H2O(l) What type of reaction is involved in the titration ? a. complexometric b. redox c. acid- base d. precipitation
Answer the following question.
A 0.5145-g sample of a water-soluble fertilizer was dissolved and analyzed for nitrogen using the Kjeldahl method. After digestion, the distilled ammonia was collected in 100 mL of 0.1334 M boric acid. This solution required 29.38 mL of 0.202 M HCl for titration to the methyl red end point. Calculate the % N (AW =14 g/mol) in the fertilizer. Type the numerical answer only.
The protein in a 0.2976 -g sample of cheese is determined by the Kjeldahl method. The sample is digested with H2SO4, the resulting solution made basic with NaOH, and the ammonia distilled into 50.00 mL of 0.09756 M HCl. The excess HCl is then back titrated using 39.87 mL of 0.05345 M NaOH. Calculate the % N and % protein of the sample.

When a sample of the CH2Cl2 layer with a volume of 7.17 mL is collected, it requires 18.65 mL of a titrant solution of S2O32- with a concentration of 0.01306 M to reach the endpoint. The reaction has a 2:1 mole ratio of thiosulfate to iodine. Determine the concentration (in mol/L) of iodine in the dichloromethane layer. Include only the numerical answer (no units).
