Physical properties of thiocarbonic acid

Thiocarbonic acid is an inorganic acid which is related to carbonic acid. Its chemical formula is H₂CS₃.

It can be synthesized through the reaction of hydrosulfide and carbon disulfide:

CS₂ + SH⁻ → S₂CSH⁻

S₂CSH⁻ + OH⁻ → CS₃²⁻ + H₂O^[1]

Thiocarbonic acid decomposes when heated:

H₂CS₃ → CS₂ + H₂S (g)
