Let's have a brief talk about acids today... Shall we?
Permit me to point out 3 things:
Firstly,
Acids can be classified into two groups, based on strength; Strong acids and Weak acids.
Strong acids are acids which completely ionize in an aqueous solution. Weak acids are acids that ionize only slightly in an aqueous solution.
Some very common examples of strong acids are Sulfuric or Tetraoxosulphate (VI) acid, Nitric or Trioxonitrate (V) acid and Hydrochloric acid.
Some common examples of weak acids are Ethanoic acid, Citric acid and Salicylic acid.
Secondly,
The Strength of an acid is also different from the Concentration of an acid, so, try not to confuse the terms Strong and Weak with Concentrated and Dilute.
A concentrated acid contains a low amount of solvent (water), while a dilute acid contains a lot of solvent.
Thirdly,
A Corrosive acid is an acid that has the ability to destroy or damage living tissue, metals, and other materials.
Some acids are more corrosive than others. For example, hydrochloric acid is a strong acid but it's not highly corrosive, while sulfuric acid is both a strong acid and highly corrosive.
Acids generally tend to be corrosive, and even weak acids can be corrosive and dangerous in high enough concentrations. However there are a few acids that are not corrosive (Eg. Caborane acid).
You can drink diluted citric acid (acid found in lemon juice), yet drinking the same concentration of sulfuric acid will result in a chemical burn. This is because sulfuric acid is not only a strong acid, but it is also highly corrosive and can therefore do a lot of damage.
Although hydrofluoric acid is a weak acid, it is also corrosive and if held, it can pass through your hand and attack your bones.
In summary, the difference between strong acids and corrosive acids lies in their chemical properties and their ability to dissociate and damage materials, including living tissue and metals.
So...
As you were, please.
