If you would like to put pineapple in your jello, I have good news for you. You can actually combine the two and get a yummy dessert ... but you have to use canned pineapple to prepare it. Jello contains gelatin (a protein, which is a processed version of collagen.
It's a cobalt oxide-aluminum oxide. Very costly and extraordinary stable pigment of pure blue colour discovered by Thenard thÃ©nard in. 1802
The +2 state is more common. The ion Co 2+ (aq) is pink. Other compounds of cobalt(II), which include both anhydrous Co 2+ and complex ions, are commonly blue. If an aqueous solution contains both cobalt(II) and chloride ions, the blue ion CoCl 4 2- forms, in equilibrium with the pink Co 2+ (aq) ion.t relatively low concentrations of chloride, the equilibrium lies far to the right, and the solution is pink. If there is a large concentration of excess chloride, the equilibrium tends to the left, and the solution tends to be blue. The equilibrium is sensitive to temperature as well as to concentration of solutes.
