What else can I help you with?
What food type show no colour change when tested with biuret solution?
Fats and oils show no color change when tested with biuret solution. This is because biuret reagent specifically tests for proteins, and fats have a different chemical composition that does not react with the reagent to produce a color change.
A solution is tested and found to have a pH of 1. The solution is?
One possibility is a 10% solution of hydrochloric acid.
What is the buiret reagent?
The Biuret reagent is a solution used to test for the presence of proteins in a substance. It works by reacting with peptide bonds in proteins to form a violet color change. This color change indicates the presence of proteins in the sample being tested.
What is universal indicator solution and how does it work?
Universal indicator solution is a mixture of several different indicators that change color in response to different pH levels. It works by undergoing a series of color changes across a wide pH range, allowing it to show the acidity or basicity of a solution. The resulting color change is then compared to a color chart to determine the approximate pH of the solution being tested.
What is the meaning of the term end point in titration and what is true about the system at the end point?
In titrations, the end point is when you have brought the tested sample to absolute neutral. At this point, if you add one more drop of titrating solution to the sample, you would change the pH sufficient to change the color of the indicator in the sample. This is the point at which you can determine the pH of the original solution, by calculating back the amount of titrating solution you had to add to the sample to neutralize it.
Would the iodine solution change colour when it is tested on a slice of bread?
No, iodine solution will not change color when tested on a slice of bread. Iodine solution reacts with starch, turning it blue-black. Bread does not contain starch in high enough amounts to produce a noticeable color change.
What food type show no colour change when tested with biuret solution?
Fats and oils show no color change when tested with biuret solution. This is because biuret reagent specifically tests for proteins, and fats have a different chemical composition that does not react with the reagent to produce a color change.
How can pH of a solution be tested?
By dissolving the pH solution a colour change will occur in the solution that should be tested.Compairing the colour of solution to the colours marked on of pH chart we can find out if the solution we tested is of alkaline nature or of acidic nature or neutral.Solutions of pH7are neutral solutions.Solutions below pH7 are acidic solutions and those above pH7 are alkaline solutions.
What would happen to cells tested with iodine solution?
Cells that contain starch will turn blue-black when tested with iodine solution, indicating the presence of starch. Cells without starch will not change color in the presence of iodine solution. This test is commonly used to identify the presence of starch in cells.
A solution is tested and found to have a pH of 1. The solution is?
One possibility is a 10% solution of hydrochloric acid.
What is starch tested for?
Iodine solution turns blue/black
What is a possible solution to a problem or statement which can be tested?
One possible solution is to design an experiment or hypothesis that can be tested using observations, data collection, and analysis. This allows for systematic investigation and evaluation of the proposed solution to determine its effectiveness and validity.
A solution is tested and found to have a pH of 1 the solution is?
The solution is acidic. A pH of 1 indicates a high concentration of H+ ions in the solution, making it strongly acidic.
How titration is done in a pharmacy industry?
In a pharmacy industry, titration is commonly used to determine the concentration of a solution. It involves slowly adding a titrant of known concentration to the solution of unknown concentration until the reaction reaches its endpoint, as indicated by a color change or other observable change. The volume of titrant used is then used to calculate the concentration of the solution being tested.
How can the pH of a solution be measured?
pH can be measured using a pH meter, pH strips, or pH indicator solution. A pH meter provides a numerical value for pH, while pH strips or indicator solution change color based on the pH of the solution being tested.
What colour will the DCPIP test give if it is positive?
If the DCPIP test is positive, the solution will change from blue to colorless or clear. This color change indicates the reduction of DCPIP by a reducing agent present in the sample being tested.
How can you tell a mixture is a solution?
You can't tell that a mixture is a solution to anything until the mixture is thoroughly chemically tested and proven.
