Trisodium Phosphate

[Twen17]

Can someone tell me if there is a shelf life to mixed trisodium phosphate? I mixed up some trisodium phosphate with RODI about 2 years ago. It’s in a glass jar. It hasn’t been touched or moved or opened in 2 years.

Is it still useable for dosing phosphate?

I’m sure there is a shelf life. You should test it to determine its strength to compare it to what it was 2 years ago.

It will last forever, as long as the water has not evaporated.
