I have blue sphere silica gel if I store it long term saturated in pink color will it break and release water or liquid inside the shoe box?
Sorry, I'm not understanding the question. Are you saying that if you try to store blue silica gel spheres long-term in a shoebox, that it turns pink and releases liquid? Or are you saying something else?cdzfan said:I have blue sphere silica gel if I store it long term saturated in pink color will it break and release water or liquid inside the shoe box?
No.cdzfan said:Will it break and leak to release water at some point?
Property of a cobalt chloride - when anhydrous it is blue, when converted to hexahydrate it becomes pink.berkeman said:Sorry, a non-chemist question if I may. Why is the OP mentioning blue turning to pink?
No, that's not how it works. Water is not there in liquid form, it is absorbed in the crystalline structure of the solid, the only way it can leave it is by a slow evaporation.cdzfan said:I have many shoeboxes and inside them I have blue sphere silica gel sachets but the silica saturated and turned pink so I thought that if I keep these sachets inside the box the pink sphere silica gel will break and release water and liquid inside the box. box wetting everything

Because when the blue form reacts with the water to turn pink, CoCl2 now has water acting as a ligand and bonding with the Co ion.
I wouldn’t call this particular case a gray area. Silica physisorbs water because of its high surface area and strongly hydrophilic—but non-covalent—interaction with water. Cobalt chloride chemisorbs water because it forms coordinate covalent bonds with water molecules.Borek said:Which is just another interesting case for discussion about gray area between physical and chemical changes.
