After recently coming out of hospital, I received several lots of
cut
flowers. Some of them had little packets of white powder to soak
into
the water before arranging the flowers and some did not. Can anyone
please tell me what the white powder consists of? Is it bicarbonate
of
soda, or what?

Many TIA

It's most likely just to keep the water 'sweet'
