Its conductivity can be enhanced by adding a small amount of an electrolyte like a salt or common acid.

Some molecules are so strong (held together with strong chemical bonds) that they resist attack by common acids.

It ionizes in aqueous solution in a similar fashion to other common acids:

Thorium is slowly attacked by water, but does not dissolve readily in most common acids, except hydrochloric acid.

The recommendations give a full list of acceptable names for common acids and related anions.

I do have access to many common acids, bases, salts and other reagents.

In the laboratory, the most common thiocarboxylic acid is thioacetic acid.

As a solvent, it is unreactive toward common acids and select non-nucleophilic bases.

It is thus comparable to hydrogen sulfide, a common inorganic acid, in its acidity.

It is not attacked by common acids or water.
