Solidification of CaCO3 and CaHPO4

[QUOTE="Hillbillychemist, post: 6407292, member: 683096"] Not sure what you are trying to accomplish here, if you just want some solid calcium carbonate (a chunk) just get a piece of chalk. When you mixed your calcium carbonate powder a tiny amount of it dissolved. When you then dried it in the oven you evaporated the water and the dissolved calcium carbonate acted as a glue binding the powder particles together as your cracker. You added nothing but water and removed nothing but water so you still have the calcium carbonate you began with. The calcium hydrogen phosphate also has a very low solubility (0.0316g/100cc cold water) so will react similarly. Since both are calcium compounds there will be no reactions between them and you will simply have chalk with some calcium hydrogen phosphate added. [/QUOTE]
