Oxalic Acid


Two acids .....

Answer 2

here is your answer Most carboxylic acids are solids at room temperature but formic, acetic, propanoic, and butanoic acids are liquids.
Many organic acids are crystalline solids in pure form (and at room temperature), e.g. citric acid, oxalic acid, benzoic acid...
By the way, some acids are gases in their pure form (like hydrochloric acid or hydrofluoric acid).
Sulphamic acid is a solid inorganic acid. There are others too. Equally, while sulphuric acid is a liquid at room temperature, it freezes to a solid at about 10 degrees C.
