(a) Calculate pCu+ for the titration of 10.00 mL of 0.05000 M of I- with 0.02500 M Cu+ standard solution when 4.500 mL, 20.00 mL and 21.40 mL of titrant have been added. Plot the titration curve for this titration using Excel or other spreadsheet software.
(b) Calculate pCu+ for the titration of 10.00 mL of 0.05000 M of Cl- with 0.02500 M Cu+ standard solution when 4.500 mL, 20.00 mL and 21.40 mL of titrant have been added. Plot the titration curve for this titration using Excel or other spreadsheet software on the same graph as (a). How does Kspvalue influence the shape of the observed titration curves?
suppose 2.3754g of copper(II) sulfate pentahydrate is heated to drive off the water of crystallization. Calculate what weight of anhydrous salt will remain?
Home ice cream makers use ice to cool a concentrated NaCl solution below the normal freezing point of water. What molal concentration of salt is needed to lower the freezing point to -3.97 C?
What was the initial temperature of the Cu metal If the final temperature of the Cu-H 2 O mixture was at twenty five degree celsius? (The specific heat of copper = 0.377 J/(g°C).)
The sample is diluted with 72.178 g of water. A 14.024 g aliquot of this solution is then titrated with 0.1097 M HCl. It required 29.55 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous waste.
The nucleus of an atom accounts for... A-most of the size and mass of the atom. B-very little of the size and mass of the atom. C-most of the atom\'s size but very little of its mass. D-most of the atom\'s mass but very little of its size.
Calculate the volume of oxygen,measured at STP, produced by the decompistion of 2.87 g of potassium chlorate.
Why does sulfuric acid protonate the nitrogen atom of the diethylamine group of lidocaine preferentially to that of the amido group
Write a balanced equation for the combination reaction described using the smallest possible integer coefficients.
Calculate the net charge of Aspartic Acid. Its given that Aspartic acid has a pK1 COOH at 1.99 and also a pK2 NH3 group at 9.90
Write a net ionic equation to explain why the pH didn't go up to about 10, as it would have if that amount of NaOH were added to distilled water or to 20mL 0.00040 M HCl, which also would have a pH of 3.40
Reactivity of monosaccharides. Give the fate (what happens to) an aldose monosaccharide in the presence of a weak oxidizing reagent (oxidation reaction). Give the fate of (what happens to) a ketose monosaccharide in the presence of H2 and a Pt cat..
in general most substances melt at a higher temperature as pressure is increased except water. justify this behavior
