Question

2. During wet corrosion in acidic
environment
O Oxygen evolution occurs
O oxygen absorption occurs
O Hydrogen evolution occurs
O Hydrogen absorption occurs​

Answer 1

Answer:

OPTION A OXYGEN EVOLUTION OCCURS .

Answer 2

During wet corrosion in an acidic environment hydrogen evolution occurs:

• Wet corrosion occurs when a metal comes in contact with a conducting liquid.
• It can be observed in a galvanic cell where corrosion of anode occurs due to its oxidation and reduction occurs at the cathode.
• At the cathode, in the absence of oxygen in an acidic environment hydrogen ion formation occurs resulting in the evolution of hydrogen gas at the cathode.
• The reaction which occurs at the cathode is as follows:

                          2H + 2e⁻→ H₂ ↑ ( reduction)

Thus, During wet corrosion in acidic  environment (3rd option) Hydrogen evolution occurs.
