Dear all

For my own purposes, I have set up a spreadsheet to work out the optimum quantities of NaClO₂ and HCl to produce CDS. I have developed that useful calculator into a facility that I hope is helpful for others.

The original Numbers spreadsheet is available online through iCloud. You will need an iCloud account to access this but if you don't have one, you can set one up for free.

I am also attaching a CSV version, which I have not tested. Hopefully it has survived the translation process. You may need to edit the '.txt' extension back to '.csv' or just insist that the file is opened by your spreadsheet app. I have also included an Excel version—again untested—and added an extra '.txt' extension, which will need to be removed before it can be opened by Excel.

Let me know how you find it and if I have made any mistakes along the way. All equations are viewable and the table and cells are not locked. There are some hidden contents that are constants and are used by the equations but do not need to be altered. Hopefully it is sufficiently clear and helpful.

I have upgraded the wizard to understand sodium chlorite powder so that you can use that in your recipes rather than always going from a solution. Just put 100 in the percentage box or the actual purity of the powder (typically 80%) and tick the 'without additives' box.

I have also uploaded a similar wizard for CDH:  www.icloud.com/numbers/0YQ-wS7gxs5LqPl6Lvu3YpLCA#CDH_calculator
and also a concentration calculator for any type of recipe:  www.icloud.com/numbers/01tmX7fOyxhvINxipa2mLOFYA#chlorine_dioxide_calculator ,
which calculates the amount of ClO₂ produced and the final concentration if that is used to produce CDS or CDH/MMS1.
