It is used as a precursor to perchlorate salts which is used in rocket fuels. It is also used for electropolishing or etching of molybdenum, aluminum, and other metals. Properties of Perchloric acid It is corrosive to metal and tissue. It has a pKa lower than It is a non-flammable and powerful oxidizer. Summary Perchloric acid is an inorganic or mineral acid that appears as a colorless liquid and is generally odorless in nature.

Any other acid is considered a weak acid. Strong acids dissociate completely into their ions in water, yielding one or more protons hydrogen cations per molecule. There are only 7 common strong acids. Examples of ionization reactions include:. Note the production of positively charged hydrogen ions and also the reaction arrow, which only points to the right. All of the reactant acid is ionized into product. Weak acids do not completely dissociate into their ions in water. There are many more weak acids than strong acids.
Most organic acids are weak acids. Here is a partial list, ordered from strongest to weakest. Weak acids incompletely ionize.
An example reaction is the dissociation of ethanoic acid in water to produce hydroxonium cations and ethanoate anions:. Note the reaction arrow in the chemical equation points both directions. The reaction proceeds in both directions. The back reaction is more favorable than the forward reaction, so ions readily change back to weak acid and water.
You can use the acid equilibrium constant K a or pK a to determine whether an acid is strong or weak. Strong acids have high K a or small pK a values, weak acids have very small K a values or large pK a values. Be careful not to confuse the terms strong and weak with concentrated and dilute. A concentrated acid is one that contains a low amount of water.
In other words, the acid is concentrated. A dilute acid is an acidic solution that contains a lot of solvent. If you have 12 M acetic acid, it's concentrated, yet still a weak acid.
