One way to differentiate between a solution and a colloid is through the Tyndall effect. In a solution, light passes through without scattering, while in a colloid, light scatters because the particles are large enough to reflect light. This can be observed by shining a light through the mixture - if the light beam is visible, it is a colloid, whereas if the beam is not visible, it is a solution.

How can you tell the difference between suspension colloid or solution?
Use the Tyndall Effect shine a light through it. If the light is scattered then it is colloidal. Both colloids and suspensions are heterogeneous. A solution will not show the beam through it's substance but the colloid will. The particles in the suspension will eventually settle at the bottom, showing that it is NOT a solution.
How could you tell the difference between an iron chloride and sodium chloride solution?
One way to differentiate between iron chloride and sodium chloride solutions is to perform a chemical test using silver nitrate. Iron chloride solution will form a white precipitate of silver chloride, while sodium chloride solution will not react with silver nitrate. Another method is to use a flame test: iron chloride imparts a yellow color to the flame, while sodium chloride does not.
What is the difference between Benedict's solution and fehling's solution?
Benedict's solution is used to test for the presence of reducing sugars, such as glucose, in a sample. It is more sensitive than Fehling's solution, which is also used to test for reducing sugars but is less commonly used due to its complexity and need for separate solutions (Fehling's A and B) to be mixed in a specific ratio before testing. Benedict's solution is a single solution that is easier to use.
What test would you use to confirm that you have a solution of FeCl3?
You can use a precipitation test by adding NaOH solution to identify FeCl3, which forms a red-brown precipitate of iron hydroxide. Another test involves adding potassium ferrocyanide, which forms a deep blue precipitate of ferric ferrocyanide. Both of these confirm the presence of FeCl3.
What is use of litmus solution?
Litmus solution is used to test whether a substance is acidic or basic. It turns red in an acidic solution and blue in a basic solution. It is commonly used in science laboratories and in various industrial applications to determine the pH of a solution.
What test can you use to differentiate solution and a pure liquid?
Distinguished Boiling Test

Need a simple method to distinguish between a beaker containing a true solution and one containing a colloidal suspension?
To do this you use the most simple of tests. (The name of the test escapes me at the moment... it might be Light Scattering.) You simply shine a small light through the beaker, and if you have a colloidal suspension, the light should be visible through the colloid. If you should have a solution, however, the light will not appear through the substance. This is because the particles in the solution are far too small to scatter light, while the particles in the colloid are large enough to be able to scatter the light.
How do you test for phenols?
Phenols can be tested using several methods, one common approach being the use of Ferric Chloride (FeCl3) solution. When a phenolic compound is added to this solution, a color change occurs, typically resulting in a purple or violet color, indicating the presence of phenols. Another method involves the use of bromine water, where phenols will decolorize the solution due to the formation of brominated derivatives. Additionally, the pH test can help differentiate phenols from other alcohols, as phenols typically exhibit acidic properties.
Can you do a flame test with NaCl in solid form or sodium chloride as an aqueous solution?
It is recommended to use the sodium chloride solution; the color in the flame test is yellow.
how do you test if a metal is gold?
There are so many hacks that you can see on tiktok on how you test this. There is a solution available in the market that you can use.

What test would you use to identify a solution of Ag₃PO₄?
Silver phosphate is not soluble in water.
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 you use the pH test?
The pH test paper is used to detrmine the pH; immerse a piece of paper in the solution and compare with the color scale.
What liquid do you use to test the pH scale?
A pH testing liquid called universal indicator solution is commonly used to test the pH scale. It changes color depending on whether the substance is acidic, neutral, or basic.
