    How do you calculate the volume/mass of SO2 released from 1m3 Sodium Bisulphite (40%w/w)solution ?

    The aim is to work out the ventilation requirements for the Sodium Bisulfite (NaHSO3) storage room to ensure COSHH compliance. From my understanding, the oxidation of NaHSO3 with air results in the formation of SO2. The vapor cloud above the bisulfite solution is composed of SO2 and H2O...

    Evolution rates of SO2 from 20% Sodium Bisulphite Solution

    Hi, Doing a bit of work on ventilation in the chemical storage room to ensure COSHH compliance. However I cannot seem to find a way to quantify the rate at which SO2 released. Current model involved using vapour pressure data to determine the concentration of SO2 in the room based on two...
