Herbal teas and fruit teas should not be confused with true teas (black, green, white, yellow, oolong, etc., which are prepared from the cured leaves of the tea plant, Camellia sinensis), as well as from decaffeinated tea, in which the caffeine has been removed.
Physical Hazard. OSHA defines a physical hazard as a chemical for which there is scientifically valid evidence that it is a combustible liquid, a compressed gas, explosive, flammable, an organic peroxide, an oxidizer, pyrophoric, unstable (reactive), or water-reactive.hysical Hazard.

Do note that solubility of ionic compounds are not absolute. In fact, solubility in water is often given as a value in g/L of water. However, generally, we define solubility as: 1  Soluble substances can form a 0.1M solution at 25 Â°C. 2  Insoluble substances cannot form a 0.1M solution at 25 Â°C.t's just not as immediate as dissolution of the more soluble ionic compounds. You are probably familiar with this phenomenon: This forms because calcium carbonate dissolves. The rock is limestone, which is usually composed of pure calcium carbonate.
