A substance, when dissolved in water, electrolytic dissociation practically does not occur: 1) lithium hydroxide 2) potassium sulfate 3) barium sulfate 4) sodium nitrate
In an aqueous solution, electrolytes dissociate into ions. These include alkali metal hydroxides (alkalis), strong and medium-strength acids, and water-soluble salts. All other compounds do not belong to electrolytes (water, oxides, insoluble bases and salts, weak or unstable acids). Let’s analyze each answer:
1. LiOH – alkali
2.K2SO4 – soluble salt
3. BaSO4 – insoluble salt, not an electrolyte
4. NaNO3 – soluble salt
Answer: 3) barium sulfate
