Detailed explanation-1: -In general, bases do not react with metals and release hydrogen gas.

Detailed explanation-2: -Bases (or alkalis) such as sodium hydroxide and potassium hydroxide are corrosive because they break down fatty acids in skin tissue and penetrate deeply. Acids generally cause greater surface-tissue damage and bases (or alkalis) produce deeper, slower healing burns.

Detailed explanation-3: -Acids corrode many kinds of metals through some chemical processes. Not all the metals react with acids in a similar way but some metals are more vulnerable to corrosion than other metals. Acid corrosion of metals is due to electrochemical processes.
