Because of the surface tention.
Answer:
This question is incomplete
Explanation:
Although, the question above is incomplete, however the correct option can be deduced from the explanation below.
Compounds/chemicals that dissolve in water to conduct electricity are Ionic/electrovalent compounds. Ionic compounds/salts are compounds that are held together by ionic/electrovalent bond. These compounds dissociate in water to form ions; the dissociated ions formed are the carriers of electric charges hence enabling the salt solution conduct electricity. Examples of these electrovalent/ionic compounds include NaCl, CaCl₂, CsF and MgO.
NOTE: Identify the ionic/electrovalent compounds in the options (from the completed question) to get your answer.
Answer:
