because distilled water does not conduct electricity and tap water does and also to see weather methanol conducts electricity.
Methanol has low conductivity because it does not ionize well in solution. Methanol molecules do not easily dissociate into ions in water, resulting in fewer charged particles available to carry electrical current. Additionally, methanol is a nonpolar molecule, which further limits its ability to conduct electricity.
There can be an aqueous solution with methanol in it. Methanol is a pure substance, so if not mixed with other substances it is a compound.
Covalent solutions have poor electrical conductivity because covalent compounds do not dissociate into ions when dissolved in solution. Since ions are needed to conduct electricity, the lack of free ions in covalent solutions results in poor electrical conductivity.
A dilute solution.
When dissolved in water, substances that dissociate into ions increase the electrical conductivity of the solution. This is because the free ions are able to carry an electric charge, allowing the solution to conduct electricity. Examples of such substances include salts like sodium chloride and acids like hydrochloric acid.
The electrical conductivity of the solution will be higher if the concentration of NaCl increase.
Sodium chloride in liquid phase and sodium chloride in water solution are electrolytes, containing ions Na+ and Cl-.
Conductivity - is measure in inverse amps.
how much free charged ions there are in a solution
Yes soap solution or any solution can be made to conduct electricity. But, when the solution is made of distilled water then electric conductivity is less compared to ordinary water. The conductivity of a solution depends on the purity of the water as electrical conductivity depends on the availability of positive and negative ions in a solution, and ordinary water contains a lot of salts i.e. NaCl which can split into NA+, Cl- ions, these ions can conduct electricity in water. But in distilled water, depending on the purity of the salts in the solution, electrical conductivity increases or decreases.
The greater the concentration of salt in an aqueous solution, the higher the electrical conductivity. This is because, with a greater salt concentration, there are more ions available to serve as a path for electron transfer in the solution.

Glucose is a non-electrolyte and does not dissociate into ions in water, so it does not conduct electricity well. This is because glucose molecules do not have free ions or charged particles that can move to carry an electric current.
The Nernst-Einstein equation relates the diffusion coefficient of a species in a solvent to its mobility in an electric field, suggesting a connection between diffusion and electrical conductivity. This equation is important in understanding the behavior of charged particles in solution, such as ions in electrolytes, and helps describe phenomena like ionic conduction and electrolysis.

I am not 100% sure, but if you add the powder into a aqueous solution contaning electrolytes and compared the conductivity before and after you added the powder into the aqueous solution, it may display a difference in conductivity.
Conductivity of frozen solution will decrease tremendously, as iones will be immobile in frozen solution. However, upon defrost, the conductivity should return to standard value, if salt has not percititated out of solution irreversibly, which is not ususally the case with conductivity standard solutions.
