The water turns a pale blue. In other words stating that it doesnt contain protein
To prepare Nessler's reagent, dissolve 7g of mercuric iodide and 35g of potassium iodide in distilled water, and then add 100g of potassium hydroxide pellets. Once the solution is clear, dilute it with water to make 1 liter of Nessler's reagent. This reagent is commonly used for detecting ammonia in solutions.
Distilled water mixed with red cabbage water will turn a bluish color due to the anthocyanins in the red cabbage affecting the pH of the solution.
A suitable reagent blank for measuring the absorbance of a protein solution mixed with Bradford reagent at 595nm would be a blank containing all components of the reaction except the protein sample, such as water or buffer mixed with the Bradford reagent. This blank will account for any background absorbance contributed by the reagent itself, allowing for a more accurate measurement of the protein concentration.
If your distilled water is turning brown when heated, it wasn't distilled very well.
Benedicts solution
To prepare Benedict's reagent, dissolve 17.3 g of sodium citrate and 1.72 g of anhydrous sodium carbonate in distilled water. Then add 0.5 g of copper sulfate pentahydrate and heat the solution until the salts dissolve completely. Adjust the volume to 1 L with distilled water, filter the solution if needed, and store in a cool, dark place.

To prepare Schultz reagent, mix one part of concentrated sulfuric acid with nine parts distilled water. Allow the mixture to cool before use. This reagent is commonly used for the detection of proteins in biological samples.
Laboratory reagent consisting of potassium phosphate and calcium phosphate, magnesium sulfate, and ammonium tartrate in distilled water
If your distilled water is turning brown when heated, it wasn't distilled very well.
Benedicts solution
benedicts test is positive when water starch and HCL keep for 30 mins because glycosidic linkages between amylose and amylopectin breaks and free ends are available to react with Benedict reagent
The reagent that is used to test for starch is a mixture of iodine and potassium iodide in water, or an Iodine - KI reagent. If the reagent turns blue-black in color, then starch is present.
Sterile or Sterilized Water - Water that meets the requirements under "Sterility Tests" in the United StatesPharmacopeia.Distilled Water - Water that is demineralized by distillation and complies with the requirements for purified water set forth in the United States PharmacopeiaDM water- Water that is demineralized by distillation, deionization, or reverse osmosis and complieswith the requirements for purified water set forth in the United States Pharmacopeia
