Sodium Hydroxide, Pellets - CAS 1310-73-2 - Calbiochem 1 Product Result | Match Criteria: Formula, Product Name A volumetric standard solution, titrated at 25°C to pH 8.6 (phenolphthalein endpoint) against NIST⢠potassium acid phthalate. The pH of a 0.05% w/w soln ~12, of a 0.5% soln ~13, of a 5% soln ~14. The melting point is the highest temperature at which crystallization may occur. Articles of Sodium hydroxide are included as well. Water (7732-18-5) LD50 oral rat ⥠90000 mg/kg Evaporation Rate:Not available. The melting point is specific for a given substance. We say that such a body melts. It is also a temperature at which a solid (crystal) turns into a liquid. 3 Effective date : 12.14.2014 Page 5 of 7 Sodium Hydroxide, 3M Created by Global Safety Management, Inc. -Tel: 1-813-435-5161 - www.gsmsds.com Contact with moisture or water may generate sufficient heat to ignite combustible materials. Sodium hydroxide in contact with acids and organic halogen compounds, especially trichloroethylene, may causes violent reactions. For full table with Density, Liquid Denity at Melting Point and Water Solubility-rotate the screen! Contact with nitromethane and other similar nitro compounds causes formation of ⦠Chemsrc provides Sodium hydroxide(CAS#:8012-01-9) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. Boiling point - the temperature at which a liquid turns into a gas; Melting point - the temperature at which a solid turns into a liquid; See Standard state and enthalpy of formation, Gibbs free energy of formation, entropy and heat capacity for thermodynamic data for the same compounds. Volumetric NaOH solns used in the laboratory must be protected from air to avoid formation of carbonate. Melting Point:-4C (25F) (5% solution) Vapor Density (Air=1): No information found. The melting point depends on the pressure. Sodium Hydroxide, 5% w/v LD50 dermal rabbit 28421 mg/kg ATE US (dermal) 28421 mg/kg body weight . rate comp. For example, the melting point of ice (frozen water) is 0 °C.
