Question

Direction: Four substances were tested for their electrical conductivity. The results are shown in the table. Study the table and answer the following questions. $S u b s tan c e B \underline{b} S u b s tan c e a t C a t h o d e S u b s tan c e a t A n o d e$ P Lights up Aluminium Oxygen $Q L i g h t s u p N o t h \in g N o t h \in g$ R Does not light up Nothing Nothing $S L i g h t s u p H y d r o \geq n C a r b o n d i \otimes i d e$ In substance Q, bulb lights up but no substance is found either at cathode or at anode, why?

Because Q is non-electrolyte.

Because Q is an element which remains unchanged when it conducts electricity.

Because Q is an electrolyte that conducts electricity when it is in the molten state.
