Petty John's Cave popular destinations of the cave. Formations in Petty John's Cave include: Stalagmites that are a type of speleothem that rises from the floor of a limestone cave due to the dripping of mineralized solutions and the deposition of calcium carbonate. Stalactites are also found in the cave. These formations hang from the ceiling or wall of the cave. There are also pillars, soda straws, cave pearls, flowstones, and cave popcorn are other formations in the cave. In addition, waterfalls can be found in the stream passage section. This cave hosts tri-colored bats during their winter hibernation because temperatures are low
Calcium carbonate equilibrium pressure must exceed total atmospheric pressure of 101 kPa, which happens at 898 °C. Calcium carbonate is poorly soluble in pure water (47 mg/L at normal atmospheric CO partial pressure as shown below). The equilibrium of its solution is given by the equation (with dissolved calcium carbonate on the right): where the solubility product for [Ca] [CO] is given as anywhere from "K" = 3.7×10 to "K" = 8.7×10 at 25 °C, depending upon the data source. What the equation means is that the product of molar concentration of calcium ions (moles of dissolved Ca per liter of solution)
