If 638.44 g CuSO4 reacts with 240.0 g NaOH which is the limiting reagent?
Sodium hydroxide is the limiting reagent.
Would albumin give a positive biuret test?
Hey. okay.. the biuret test is a test for peptide bonds. when CuSO4 is added to KOH, an alkaline solution, nitrogen atoms from the peptide bond forms a purple compound with the Cu2+ ions. hope this helps! read it in a text book.
What is the product of the reaction between CuSO4 and KF?
CuF2+ K2SO4
HCL CUSO4 equation?
HCl + CuSO4
What is the Formula of hydrated copper sulphate?
CuSO4
What substance is used as a control in a Biuret test?
Biuret reagent is made up of sodium hydroxide and copper sulphate.
If 638.44 g CuSO4 reacts with 240.0 g NaOH which is the limiting reagent?
Sodium hydroxide is the limiting reagent.
What are the conclusions from testing the Biuret reagent for protein?
The reagent used in the Biuret Test is a solution of copper sulfate (CuSO4) and potassium hydroxide (KOH). The KOH is there to raise the pH of the solution to alkaline levels; the crucial component is the copper (II) ion from the CuSO4. When peptide bonds are present in this alkaline solution, the copper (II) ions will form a coordination complex with four nitrogen atoms involved in peptide bonds. Copper Sulfate solution is a blue colour, but when the copper (II) ions are coordinated with the nitrogen atoms of these peptide bonds, the colour of the solution changes from blue to violet. This colour change is dependent on the number of peptide bonds in the solution, so the more protein, the more intense the change. When the peptides are very short, the solution turns a pink colour, rather than violet.

Detect peptide bond?
by conducting the biuret test. the positive result of biuret test will give you the purple blue ring on top of the solution.(albumen/milk + cuso4 +NaOH)
What is the product of the reaction between CuSO4 and KF?
CuF2+ K2SO4
Why do color change in biuret test?
The copper atoms of Biuret solution (CuSO4 and KOH) will react with peptide bonds, producing a color change.A deep violet or blue color indicates the presence of proteins and a light pink color indicates the presence of peptides.http://faculty.clintoncc.suny.edu/faculty/michael.gregory/files/bio%20101/bio%20101%20laboratory/chemical%20composition%20of%20cells/chemical%20composition%20of%20cells.htm
Do a 5m cuso4 and 5m cuso4 5 h2o contain the same quantities of cuso4?
Yes. They do not contain the same proportion of CuSO4, however. The moles of CuSO4 . 5 H2O are more massive.
HCL CUSO4 equation?
HCl + CuSO4
What is the chemical equation for hydrated copper sulphate?
CuSO4 . 2H2O
What is the Formula of hydrated copper sulphate?
CuSO4
Is CuSO4 an ionic or covalent compound?
CuSO4 is ionic.
