Alkaline solution crystallization process
Thread Content
Are the characteristics of the alkaline solution crystallization process the same as those of the water freezing process—characterized by expansion?

The process of water freezing is actually one in which heat transfer reduces the movement of water molecules; as the movement of these molecules slows down, ice is formed. Since the molecular structure of ice allows for more space compared to that of water, ice occupies a larger volume than water. Under normal conditions, between 0 and -4 degrees Celsius, the volume of ice increases as the temperature drops. So, does alkali solution expand in volume when it crystallizes, just like water does, and is this expansion destructive?
The crystallization of the alkaline solution is mainly the precipitation of sodium hydroxide, right?
It’s “precipitation”; doesn’t the crystalization process also involve crystal growth? Is there a difference between the molecular space of sodium hydroxide crystals and the space of its ions in water?
