Sodium Hydroxide 96% AR Grade Reagent
Cas Number:1310-73-2
Formula: NaOH
Molar Mass:40
EC Number:215-185-5
Physicochemical properties:
Molten white granules or strips with small pieces. It is easy to absorb moisture and carbon dioxide in the air. 1 g is dissolved in 0.9 ml of cold water, 0.3 ml of boiling water, 7.2 ml of absolute ethanol, 4.2 ml of methanol, and dissolved in glycerin. It is very hot when dissolved in water or ethanol or when the solution is mixed with acid. The solution is strongly alkaline. The relative density (d 25) is 2.13. The melting point is 318 ° C. The boiling point is 1390 °C.
Usage:
Basic analytical reagents for a wide range of applications. Prepare standard lye for analysis.Neutralization of acid. Sodium salt manufacturing.
Packing:
500g/25kg
