What is the chemical indicator used to test 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 the common name for potassium permanganate?
Yes. Sodium permanganate is an ionic compound comprising mono-atomic sodium cations and polyatomic permanganate anions.
What is the symbol for sodium potassium?
The symbol for sodium is Na and the symbol for potassium is K.
What is the chemical formula for quantitative Benedict's reagent?
Benedict's reagent is an aqueous solution of copper (II) sulfate, sodium carbonate, sodium citrate dihydrate and 2,5-difluorotoluene.
the name of the product formed when sodium reacts with potassium?
sodium chloride
How do you make homemade biuret?
To make homemade biuret reagent, mix together copper sulfate (0.1g), sodium hydroxide (0.3g), and potassium iodide (0.6g) with distilled water (100ml). Allow the mixture to dissolve completely. This solution can be used for testing the presence of proteins.
Why biuret reagent only kept in plastic bottle?
Biuret reagent should only be kept in a plastic bottle because it reacts with glass, which can contaminate the solution and give inaccurate results. Plastic is chemically inert and does not react with the reagent, ensuring the accuracy of the test results.
What substance is used as a control in a Biuret test?
Biuret reagent is made up of sodium hydroxide and copper sulphate.
Can you use sodium tartarate instead of amonium tartarate?
It's difficult to offer an answer without knowing your purpose.
What the uses of sodium hydroxide in the Biuret test?
Sodium hydroxide is used in the Biuret test to create an alkaline environment, which helps to denature proteins and peptides. This denaturation allows the copper ions in the Biuret reagent to form a colored complex with the peptide bonds in proteins, indicating the presence of proteins in a solution.
What is the Baeyer s reagent?
Baaeyer reagent is used to identify double or triple bonds in organic compounds. The reagent is a cold solution of 1 % potassium permanganate in water containing also 10 % sodium carbonate.
What chemical formula for Fehlings reagent?
The Fehling A solution contain copper sulfate.The Fehling B solution contain sodium potassium tartrate and sodium hydroxide.
What is the chemical indicator used to test 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 the common name for potassium permanganate?
Yes. Sodium permanganate is an ionic compound comprising mono-atomic sodium cations and polyatomic permanganate anions.
Which salts are used in the kitchen?
The commonly used isSodium chloride but Sodium bicarbonate (baking powder) and Sodium tartarate are also used.
What is the composition of fehling's solution?
Fehling's solution is made up of two separate solutions: Fehling's A (copper sulfate solution) and Fehling's B (potassium sodium tartrate and sodium hydroxide solution). When combined in equal parts, these solutions are used to test for the presence of reducing sugars like glucose in a chemical sample.
What are 2 different salts and their uses?
Examples: Sodium chloride applications - spice for foods - preservative for foods - preparation of sodium, chlorine, sodium hydroxide - roads deicing - soaps fabrication etc. Potassium iodide applications: - iodizing additive for salt - protective agent against contamination with radioactive iodine - quenching reagent in biochemistry - reagent in organic synthesis
