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.
What was the flame test original use?
The flame test is used for the qualitative determination of some ions in solution.
What test would you use to confirm that you have a solution of FeCl3?
I would do a reverse of the Ferric Chloride test. Take the FeCl3 solution and add a solution containing phenols in it. If red, blue, green, or purple colors form, you've got FeCl3.
How do you test for nitrates and phosphates in water?
For phosphates you can use molybdate solution but be careful it contains sulfuric acid.
Why use iodine solution to test for starch?
The test is positive with starch because the iodine takes up a position in the centre of the starch helix which is blue black.
What test can you use to differentiate solution and a pure liquid?
Distinguished Boiling Test

What can you use to test for lithium hydroxide?
Universal Indictor to test if it is an alkaline solution
What liquid do you use to test the pH scale?
You use Universal Indicator solution.
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.
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.
What was the flame test original use?
The flame test is used for the qualitative determination of some ions in solution.
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.
You can use what to respond to problem-and-solution essay test questions?

What test would you use to identify a solution of Ag₃PO₄?
Silver phosphate is not soluble in water.
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.
