Methanesulphuric acid is weaker than sulphuric acid. A number of inorganic protonic acids act as acids in it while the strong bases are fully protonated. The acid‐base titrations in it with strong acids indicate that the bulk of the current is carried by CH 3 SO 3 H 2 + and CH 3 SO 3 − ions. The conductance measurements indicate that the order of the acid strength is: H[B(HSO 4 ) 4 ] > HSO 3 F > H 2 S 2 O 7 > HAs(HSO 4 ) 4 > HSO 3 Cl > H 2 SO 4 > HX (XBr > Cl) > H 2 SeO 4 .
