Randy I notice my used Lime Soda I used that was purple turn back to white when sitting out overnight. I didn’t have time to toss it so I left it out in an open container. Does this mean it can rejuvenated itself by sitting out?
No, soda lime cannot rejuvenate. Calcium hydroxide absorb CO2 and turns into calcium carbonate. The reaction is in irreversible in room temp. The color change is just they way the dye work.
