Which substance is an electrolyte?
(1) CH3OH (3) H2O
(2) C6H12O6 (4) KOH


Sagot :

KOH is an electrolyte. Which means that is in a solution or when molten, ionizes and conducts electricity. 

Answer:

The answer is 4) KOH

Explanation:

Electrolytes are substances which ionize when dissolved in water. They are classified as:

Strong electrolyte: Which completely ionize when in water. Eg: NAOH, KOH (produces K+ and OH- ions when dissolved in water)

Weak electrolyte: partially ionize when in water. Eg: Acetic acid

Non-electrolyte: Do not ionize at all in water. Eg: Alcohols such CH3OH, sugars such as glucose (C6H12O6).
