Question

Evolution of hydrogen type corrosion occurs in _______ environment

Answer 1

H2 gas liberates in form of bubbles near the cathode thus the hydrogen evolution type of corrosion is nothing but displacement of H+ from acidic solution by metal ions
all the metals above H2 in the electro chemical series get dissolved in acidic solution with simultaneously evolution of hydrogen
