One test to determine if a mixture is a true solution or a colloid is the Tyndall effect. If light passing through the mixture scatters, making the beam visible, it suggests the presence of larger particles characteristic of a colloid. In contrast, a true solution will not scatter light and the beam will be invisible.
What else can I help you with?
When copper sulphat is stirred into a water water turns blue what two tests carry out to see whether this mixture is suspension or a solution?
A suspension is cloudy or will not allow light through, a solution is clear even though it can be colored. One way to test is to shine a light through the water mixture and see if it allows light to come through without breaking it up or dimming it. If it does it's a solution, if not its a suspension.
Does the litmus paper test determine if an aqueous solution is basic?
Yes, the litmus paper test can determine if an aqueous solution is basic. If the litmus paper turns blue, it indicates that the solution is basic. If it remains red, the solution is acidic.
What is an example of a test a chemist might do?
A chemist might conduct a titration test to determine the concentration of a solution by reacting it with a solution of known concentration. This allows them to calculate the amount of substance present in the sample.
What can you use to find out if the pH of the mixture has changed to 7?
You can use a pH meter to measure the pH of the mixture and determine if it has changed to 7. Additionally, pH test strips or universal indicator solution can also be used to identify if the pH has reached 7 by changing color accordingly.
A test that can be used to determine whether a solution has potassium sulfate?
To determine if a solution contains potassium sulfate, you can perform a flame test. When a sample of the solution is heated in a flame, the potassium ions will emit a lilac flame color, which is characteristic of potassium compounds. This can help confirm the presence of potassium sulfate in the solution.
What are two tests you can use to determine if a mixture is a solution or a mechanical mixture?
To determine if a mixture is a solution or a mechanical mixture, you can use a filtration test and a visual observation test. In a filtration test, a solution will pass through a filter without leaving residue, while a mechanical mixture will leave solid particles on the filter. For visual observation, a solution appears homogeneous and clear, while a mechanical mixture shows distinct phases or components that can be seen separately.

What test is used to determine if excess hypochlorous acid is present in the oxidation mixture?
KI
How would you determine whether milk has reducing sugars?
Test it with Benedict's solution.

How would you determine if you had diabetes using the benedict's solution test?
if you have reddish brown result.

How could you test a liquid mixture to find out whether it's a solution or a colloid?
To test whether a liquid mixture is a solution or a colloid, you can perform a simple visual test using a beam of light, known as the Tyndall effect. Shine a flashlight through the mixture; if the light is scattered and visible, it indicates the presence of larger particles typical of a colloid. In contrast, if the light passes through without scattering, the mixture is likely a solution, where the solute particles are too small to scatter light. Additionally, you can let the mixture sit; if it separates into distinct layers, it may indicate a colloidal or suspension nature.
Is it advisable to use just one type of indicator to determine the nature of an unknown solution?
No; every test must be confirmed by another test.
How do know fat is present in a solution?
You can determine the presence of fat in a solution through several methods, such as the use of a paper test. When a small amount of the solution is placed on a piece of paper, if a translucent spot appears after drying, it indicates the presence of fat. Additionally, chemical tests like the Sudan III test can also be used, where a color change confirms the presence of lipids. Finally, techniques like chromatography can separate and identify fats in a mixture.
