Properties of 40% sodium hydroxide solution?
Thread Content
Gentlemen, may I ask at what temperature does a concentrated 40% sodium hydroxide solution freeze? Thank you!
You can conduct an experiment yourself: one low-temperature refrigerator, one thermometer, and one beaker. Made by oneself; one can never forget it. :lol
It is generally between 4-5 degrees; crystallization occurs at this temperature
It crystallizes at around 25 degrees Celsius, as calculated by software; I’m not sure if it’s accurate. This post was last edited by mailwwc on 2008-2-18 11:32.]
