    Is This Borax Or Baking Soda

    Almost 2 years ago I closed the pool at our old house for the winter. I took a box of white powder and dumped it into an old coffee can for storage. I very cleverly did not label the can. Then we sold the house the following February. Fast forward to this summer when I finally get the pool up at the new house, I've got a coffee can of something. I think it's borax, it doesn't appear fine enough to be baking soda. Is there a way to test for sure?

    I suppose you could try to test dissolving it in water and see how it affects TA & pH compared to what you'd expect for each.

    Use a fixed measure of both water and the substance and you should be able to predict after results.

    a coffee can of something ????? throw it away. if it's been sitting in a can for two years it's no good anyways. why chance it . could be something toxic. both products are very inexpensive.
