Which substance is an electrolyte?

C2H5OH
C6H12O6
C12H22O11
CH3COOH

100% sure CH3COOH

its CH3OOH i just used it and got it correct on castle learning

The empirical formula is not enough to know with certainty; however, from the limited information available, the only one I see is acetic acid, the last one, and it is a WEAK electrolyte. I think all of the others are non-electrolytes.

To determine which substance is an electrolyte, we need to understand what an electrolyte is.

An electrolyte is a substance that conducts electricity when dissolved in water or in a molten state. It does so by forming ions, which are atoms or molecules that have a net electric charge. In an aqueous solution, these ions can move freely and carry an electric current.

Let's analyze each substance to identify if it is an electrolyte:

1. C2H5OH (ethanol): Ethanol is a covalent compound that does not dissociate into ions when dissolved in water. Therefore, it is not an electrolyte.

2. C6H12O6 (glucose): Glucose is another covalent compound and does not dissociate into ions in water. It does not conduct electricity and is not an electrolyte.

3. C12H22O11 (sucrose): Sucrose, commonly known as table sugar, is also a covalent compound that does not dissociate into ions in water. It does not conduct electricity and is not an electrolyte.

4. CH3COOH (acetic acid): Acetic acid is a weak acid and dissociates partially into ions when dissolved in water. It forms acetate ions (CH3COO-) and hydrogen ions (H+). Since it can produce ions and conduct electricity, it is considered an electrolyte.

Therefore, the substance that is an electrolyte out of the given options is CH3COOH (acetic acid).

C2H5OH
