the student is now told that the four solids, in no particular order, are aluminum chloride ( alcl3 ), sugar ( c6h12o6 ), butanoic acid ( c3h7cooh ), and potassium bromide ( kbr ). assuming that conductivity is correlated to the number of ions in solution, rank the four substances based on how well a 0.20 m solution in water will conduct electricity.

In order of conductivity, calcium bromide, potassium bromide (KBr), benzoic acid, and sugar are the least conductive materials. Benzonic acid, Ca2Br KBr C6H5COOH, and C6H12O6 (sugar).

How is electrical conductivity tested?

You can test a material by inserting something between the wire's two free ends. Put the free end of the wire on one side of the object and the other end on the other side. The substance is conductive if the bulb illuminates; otherwise, it is an insulator.

How can copper wire's conductivity be determined?

The opposite of resistivity, which is defined as resistance times cross-section area divided by length, is conductivity. Consequently, measure the length and resistance using a micro-ohmmeter.
