Always communicate exact product needs and specifications to ensure storage tanks are capable of successfully storing the concentration of sodium hydroxide.
Sodium Hydroxide Specific Heat Capacity Upgrade To AFor the best experience, you should upgrade to a modern browser with improved speed and security.Storing above 70F is recommended for concentrated caustic to prevent freezing and promote fluidity. Sodium hydroxide has a reactive and alkaline nature that contributes to its many applications. Adguard premium serial numberThis inorganic, ionic compound is a strong base capable of increasing solution pH, buffer against pH changes, and drive pH-dependent chemical reactions. Badaga dance songs free downloadNaOH is also used for various other chemical processes, such as saponification in soap making. More obsolete and historical names are soda lye, white caustic, and sodium hydrate. As a white solid or a colorless solution, sodium hydroxide is an odorless, caustic chemical characterized by strongly alkaline corrosive properties, ingestion toxicity, reactivity with various chemicals, and incompatibility with certain metals. Due to its very real hazards, NaOH should always be stored and handled according to regulatory guidelines. ![]() Sodium hydroxide is less soluble in polar solvents such as methanol but is readily soluble in water up to a 50 wt solution, which will have a pH around 14. ![]() When dissolving solid NaOH in water or a strong acid, the ionic dissociation process can be violently exothermic, rapidly releasing significant heat energy. Upon ionic dissociation, free hydroxide ions, (OH - ), will react with free protons, (H ), to form water and increase solution pH as H ions decrease and OH - ions begin to accumulate in excess. At 68F (20C), a 50 NaOH solution will have a viscosity rating around 78cp ( centipoise; 1cp 1mPas ). For reference, water is around 1.0cp at this temperature and olive oil around 85cp. From its increased viscosity, liquid sodium hydroxide is a chemical prone to find or create leaks in its containment. It has been termed a slippery chemical due to its ability to find a leak path wherever one exists. Secondary containment measures are required due to the leak-seeking nature and chemical dangers of NaOH. Methods should be utilized to maintain solution temperature above 70F for both indoor and outdoor containers to ensure fluid viscosity and prevent precipitation (crystallization) of the solution. For plumbing to the tank, flexible connections with fittings and integrally molded flanges are recommended to help prevent leaks and extend service life in storage containers holding NaOH. These metals include aluminum, lead, tin, zinc, and the alloys of zinc such as brass and bronze. Galvanized steel should also be avoided due to the presence of zinc in the protective coating. Sodium hydroxide will chemically attack these metals, releasing them into the solution where the high pH and presence of water leads to the generation of flammable and explosive hydrogen gas. Carbon steel is recognized as generally safe for the handling and storing of NaOH, but will chemically attack this mild steel at elevated temperatures. However, care should be made to avoid incompatible materials and their proximity to NaOH storage containers.
