Test for presence of water in anhydrous copper sulphate?
In the presence of water the white anhydrous copper sulfate become blue.
How can you see copper sulphate dissolve in water?
Take some copper sulfate solid and add it to a beaker of water. Stir and you will see that the solid slowly disappears to form a blue solution. Copper sulfate has dissolved and is therefore soluble in water. Anhydrous copper sulfate is a white solid while hydrated copper sultate (CuSO4.5H2O) is blue.
What element is responsible for the cloudy solution in the silver nitrate test?
Sodium - Na. When silver nitrate is mixed with Sodium Hydroxide, Sodium Iodide, Sodium Phosphate a precipitate forms.
What the uses of sodium hydroxide in the Biuret test?
To alkaline the medium so that the reaction can take place
What substance is used as a control in a Biuret test?
Biuret reagent is made up of sodium hydroxide and copper sulphate.
What test indicator is used to detect protein?
To test for protein. Biuret or solutions of sodium hydroxide and copper sulfate. Tested with a dropper a + result will be purple or something
What is biuret test?
The biuret test is a chemical test used for detecting the presence of peptide bonds. In a positive test, a copper(II) ion is reduced to copper(I), which forms a complex with the nitrogens and carbons of the peptide bonds in an alkaline solution. A violet color indicates the presence of proteins. by:Mr. Dael, Dan Rameil R.ZSCMT II-BSMB
How do you test for copper ions?
When copper react with sodium hydroxide, copper hydroxide is one of the products which has a distinct colour, so... 1) Add a few drops of dilute sodium hydroxide to the solution you wish to test for copper ions 2) If a blue precipitate forms (copper hydroxide is insoluble in water), then it's likely that copper ions are present 3) To confirm the presence of copper ions, add ammonia solution & if the precipitate dissolves, forming a deep blue solution, you know copper ions are present
How is Benedicts test used to determine the glucose content of a sample of urine in blood?
Aqueous is mixed with Benedict's reagent, a solution of copper sulfate, sodium hydroxide, and tartaric acid. The mixture is heated. Carbohydrates which react with Benedict's reagent to reduce the blue copper (II) ion to form a brick red precipitate of copper (I) oxide are classified as reducing sugars.
How can you test for protein?
Buiret's TestTests for Peptide bonds. this cannot be used to test for free amino acids.
Why do you have to keep fehling's A with fehling'a B?
Fehling's A and Fehling's B are used together in the Fehling's test to detect the presence of reducing sugars, such as glucose. Fehling's A is a copper(II) sulfate solution, while Fehling's B is a complex solution of potassium sodium tartrate and sodium hydroxide. They work together to oxidize the sugar, causing a color change that indicates the presence of a reducing sugar.
What color does sodium hydroxide burn in a flame test?
Bright yellow :: This is the sodium ions. Any sodium compound will give a flame test colour of yellow/

What happens to color of copper suphate crystals when heated in a test tube?
The dehydrated copper sulfate is grayish-white.
Test for presence of water in anhydrous copper sulphate?
In the presence of water the white anhydrous copper sulfate become blue.
How do you prepare Benedicts reagent?
You can use it to test the glucose in urine to see if someone has diabetes or not.
