The importance of ammonia in the formation of salt crystals
The results show that the solutions in Bowls 1 and 2 that contained only salt, water and bluing did not have much crystallization. The crystallization of salt increased when ammonia was added to Bowls 3 and 4. The more ammonia was added, the more crystallization occurred.
|Bowl 1||Crystal height of 2.5mm on sponge. Some crystal on edge of owl.|
|Bowl 2||Crystal height of 2.8mm on sponge. Some crystal on edge of bowl.|
|Bowl 3||Crystal height of 5.3mm on sponge. Salt crystal grown above bowl height.|
|Bowl 4||Crystal height of 8.2mm on sponge. Salt crystal overflowing bowl.|
Handle the ammonia carefully.
