Hot ice

[Jburns]

Hey guys, I am making up some hot ice with some Sodium ethanoate/Acetate but the only recipe I can find which is on the RSC website does not state if I should be using anhydrous or with water.

What do you guys use? I only have anhydrous and the recipe says to use 12.5 ml of water but this doesn't seem to be enough. Should I be using the hydrated stuff instead?

The RSC sheet I just found said use the 3-water so you will need some more water.

Thats what I thought so added about 81ml of water which is think is the right weight.

Hello!
Can you let me know which link this was and I'll get it fixed?
Looking at what I can see on our site, both these recipies for 'hot ice' say sodium ethanoate-3-water

It was the first link of yours. It mentions it in the equipment list which I missed but doesnt say it in the main body.
