Standard Operating Procedure - Chemical Engineering

Sulfuric acid, also spelled sulphuric acid, is a highly corrosive mineral acid. Its corrosiveness on metals, stones, skin, eyes and flesh and other materials can be mainly ascribed to its strong acidic nature and if concentrated strong dehydrating property and strong oxidizing property. The historical name of this acid is
