Chemistry / How can I grow NaCl crystals?
« on: 09/08/2017 12:34:55 »
Need some help please. I have been trying to grow sodium chloride crystals for a while now. Trying all I can think of. I boil tap water and add table salt untill I have some on the bottom that won't dissolve. I continue to boil the water down a bit to make sure it is super saturated. I then let it cool, filter it, then let it sit for a day in a glass jar. I then hanh a rock salt crystal on a thread midway. The seed crystal disolves over a day or so. I repeat. Same thing. I have added a few crystals to the jar and they sit on the bottom for a long time. I rehang a seed and it dissolves. What am I doing wrong?
