Electrolysis hydrocloric acid and both of the electrode uses a platinium what will happen to both of the electrode?

Hydrogen gas  is evolved at the cathode and chlorine gas at the anode.

Explanation:

The solution will ionise.  Hydrogen ions, H+, will migrate to  the negative cathode ( where the current leaves the solution and chloride ions Cl- will migrate the the positive anode.

mention the spill to the teacher clean the area and throw the broken pieces away

explanation:

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
