An electrolyte is any substance containing free ions that make the substance electrically conductive. So the substance will have a negative charge or a positive charge that can be indicated by a + sign or a - sign in front of it's chemical formula.
The color change that occurs when iodine solution is added to starch is a dark blue or purple color. This reaction is commonly used to test for the presence of starch in a solution.
you would not see the same effect because there is sugar in one and not in the other
To test if ink is an indicator, you can dip litmus paper or pH paper into the ink solution to see if there is a color change indicating a change in pH. You can also add a few drops of ink to a solution with known acidity or alkalinity to observe any visible changes in color. Additionally, you can perform a titration using the ink solution to determine its pH level.
A sandwich is a mixture not a solution as you can easily see the parts. They are not evenly distributed though out as would be sugar in water.

Lugol's Solution
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.
The reaction is:Mg + 2 HCl = MgCl2 + H2(g)You will see a release of hydrogen if a lighted match is placed near the test tube - you hear a click.
The color change that occurs when iodine solution is added to starch is a dark blue or purple color. This reaction is commonly used to test for the presence of starch in a solution.
what would happen if scientists were testing to see if a substance was safe to drink and used phenolphthalein as an indicator and what would happen if the test was done using methyl orange
So you can tell if the solution is an acid or a base
you would not see the same effect because there is sugar in one and not in the other
See if it can carry a charge.
When you add items that can be dissolved, and it doesn't dissolve in the liquid, it means that it is saturated.
You would see the formation of a precipitate which would be lead chloride.Pb(NO3)2(aq) + 2NaCl(aq) --> 2NaNO3(aq) + PbCl2(s)
Yes Pottasium is an Electrolyte, you see a electrolyte is a mineral that that disolves in water, and carries an electric current.In your body, potassium, sodium and chloride are the electrolyte minerals. Since the body is made mostly of water, these electrolytes can be found everywhere in your body.
