1000 mL 1 M $$CuSO_4(aq)$$ is electrolysed by 9.65 amp current for 100 sec using $$Pt-$$electrode. Which is incorrect statement?

Iron nails rust fast when used for fixing plates or strips of aluminium on a building. Similarly, a water pipe made of iron corrodes faster when connected to a pipe of copper. This happens because of the?

The standard reduction potential for the half-cell reaction, $$Cl_2+2e^-\rightarrow 2Cl^-$$ will be:
$$Pt^{2+}+2Cl^-\rightarrow Pt+Cl_2, E^o_{cell}=-0.15$$V;
$$Pt^{2+}+2e^-\rightarrow Pt, E^o=1.20$$V

Match the column I with column II and mark the appropriate choice.

How much electricity in terms of Faraday is required to produce $$100$$g of Ca from molten $$CaCl_2$$?

Electrical conductance through metals is called metallic or electronic conductance and is due to the movement of electrons. The electronic conductance depends on:

Which of the following is the correct cell representation for the given cell reaction?
$$Zn+H_2SO_4\rightarrow ZnSO_4+H_2$$

A galvanic cell has electrical potential of $$1.1$$ V. If an opposing potential of $$1.1$$ V is applied to this cell, what will happen to the cell reaction and current flowing through the cell?

How long would it take to deposit $$50$$g of $$Al$$ from an electrolytic cell containing $$Al_2O_3$$ using a current of $$105$$ ampere?

If a current of $$1.5$$ ampere flows through a metallic wire for $$3$$ hours, then how many electrons would flow through the wire?
