Detailed explanation-1: -A strong acid is one that completely ionizes (dissociates) in a solution. (See Appendix for a complete list of Strong Acids.) All acids in this class are highly corrosive chemicals.
Detailed explanation-2: -Acids and bases have a high reactivity with such chemicals, which means that if they come into contact with them, they will create salts and destroy the original component, causing damage to our skin. Another crucial reason is that when strong acids and bases come into contact with water, they dissociate very quickly.
Detailed explanation-3: -Strong acids can be corrosive because they donate all the H+ to water. A high concentration of H+ in water can react with biological tissue. Protective clothing must be worn when handling strong acids.
Detailed explanation-4: -No, all acids are not corrosive in nature. Certain acids like acetic acid present in vinegar, citric acid present in citrus fruits, lactic acid present in curd, oxalic acid present in tomatoes, etc, are part of our food and non-corrosive in nature.
