The message

Stick to computing your Khemistry is not good enough:-)

Inorganic bit
The composition of fizzy stomach cure things works on the fact that the
solution is alkaline and neutralises stomach acidity.
The citic/bicarbonate mix contains excess bicarbonate hence the resultant
drink is alkaline and does its work.

And how does this differ from what I wrote?

I thought you were inferring the citric acid cancelled the bicarb in term s
of alkalinity.

Organic bit
Under normal conditions (but excluding light) the hormone rooting
mixture we
are discussing will last indefinately even in the presence of hydrared
magnesium silicate. The only ingredient that may cause problems is any
fungicide in the mix (I have no knowledge of that)



Why does it carry a 'use by' date?

Some don't (as per original post by thesquire) but I suppose these days
most things carriy a use before date. It helps stock rotation.
Just had a look at salt , olive oil and asprin all of which have expiry
dates and none of these have any shelf life problems.

Let's get back to discussing Linux:-)
