Na 2 Cr 2 O 7 + 3 SO 2 + H 2 O → Cr 2 (SO 4) 3 + 2 NaOH Since 33% of the anion charges are due to hydroxy ions the basicity is 33% (but in tanning jargon it is known as 33% reduced). Products with higher basicities, e.g. 42% or 50% may be obtained by the addition of sodium carbonate , these are often used in combination with sodium formate .

A conversion factor is included into the original first coefficients of the equations to provide the pressure in pascals (CR2: 5.006, SMI: -0.875). Ref. SMI uses temperature scale ITS-48. No conversion was done, which should be of little consequence however.
