Both Dissolve. Why Only Salt Conducts? Electrolyte Solutions

Two clear cups, one hidden difference: mobile charge carriers. Follow salt and sugar on one testing bench, see why dissolving is not enough, and understand why a dim lamp does not automatically mean a weak electrolyte. Includes the story of Arrhenius and two exam questions that ask you to predict and explain. 0:00 Why only one cup conducts 0:33 Freeing the charge carriers 1:19 Dissolving without making ions 1:56 Arrhenius and the invisible ions 2:33 What strong really means 3:10 Why weak still conducts 3:45 Dilution is not weakness 4:22 Question 1: solid salt, salt water or sugar water? 4:58 Question 2: does dilution make salt weak? 5:31 Three ideas to keep 6:07 Next: acids, bases and pH #chemistry #electrolytes
