Reaction at cathode : M+ + e- ⟶ M Product at anode : Oxygen
(i) Strong electrolyte — Sodium (Na+) ions and hydroxide (OH-) ions. (ii) Weak electrolyte — Ions (H+, HCO3, CO32- ) and molecules (H2CO3) (iii) Non-electrolyte — Molecules of sugar soln.
Anode is the oxidizing electrode. Reason — The anions donate the excess electrons to the anode and are oxidized to neutral atoms. Hence, the anode is the oxidizing electrode by which…
Copper, a brownish pink metal is deposited at the cathode when acidified aq. CuSO4 soln. is electrolysed with copper electrodes
(i) Which electrode to your left or right is known as the oxidising electrode and why? (ii) Write the equation representing the reaction that occurs. (iii) State two appropriate observations for the above electrolysis reaction.(i) The electrode connected to the positive terminal of the battery (i.e., electrode on the left) is the oxidizing electrode as anions donate excess electrons to the anode and are…
Liquid carbon tetrachloride is a non-electrolyte
Solid lead bromide is a non conductor of electric current since it's ions are not free and held together by strong electrostatic force of attraction. The ions become free in…
