Graph showing the freezing point of caustic solution.

"The freezing point-solubility curve of aqueous sodium hydroxide in the region near the anhydrous-monohydrate eutectic". Journal of Physical Chemistry. 66 (10): 2051. doi: …

2004年4月7日 · My books indicate that a 25% solution of sodium hydroxide should have a freezing point of around -18 deg C. However a local reputable reagent supplier tells me that their 25% solution freezes on a cold (say 0 deg C) day.

hile 50% begins freezing at 52°F. Caustic Soda is corrosive and can burn and damage eyes, skin, mucous me. ranes and any other ex-posed tissue. If inhaled, irritation of the respiratory system may occur wi. coughing and breathing diffi-culty. Though unlikely to …

In this comprehensive guide, we will explore the multiple aspects of sodium hydroxide, including its uses, importance in CIP additives, freezing points, associated hazards, and price fluctuations.

2019年10月22日 · concentrated sodium hydroxide is best stored at temperatures above 70°F to prevent freezing, caustic deposition, and promote fluidity through increased viscosity.

2016年11月20日 · Sodium hydroxide does change the freezing point based on the concentration. It is not a linear graph. The lye solution recommended on this site is one pound of sodium hydroxide (100%) per five gallons of water. I believe that would be around a 2.3% solution. I'm not sure what the freezing point would be for that particular concentration.

2024年10月10日 · The stoichiometric factor for sodium hydroxide from sodium is 1.740. Analysis for this analyte is based on water solubility. * All sampling instructions above are recommended guidelines for OSHA Compliance Safety and Health Officers (CSHOs), please see the corresponding OSHA method reference for complete details.

73% Sodium hydroxide has a freezing point of approximately 145.4oF ( 63oC). Anhydrous (100%) sodium hydroxide is a white translucent solid with a melting point of approximately 590oF ( 310oC).

Freezing Points – Potassium Hydroxide 50% Solution Freeze at 36°F (2°C) 45% Caustic Potash Solution Freeze at -22°F (-30°C)
