How to prepare 50% potassium sodium tartrate?
It is obtained by dissolving 52.2 g of potassium sodium tartrate tetrahydrate in 47.8 mL of water.
But many people think it is 50 grams of potassium sodium tartrate dissolved in an appropriate amount of water, with the volume finally adjusted to 100 ml in a volumetric flask. Which one is correct?
Reply to 3# 15049139054: Actually, I do the same thing; it’s necessary to define this issue clearly~~~~
If potassium sodium tartrate tetrahydrate is used, the mass required should be 62.7 grams. Regarding the issue mentioned on the third floor, it is often asked; you can check out this post at http://bbs.hcbbs.com/thread-896926-1-4.html where I have answered it. Some people think that fixed capacity is more premium, but in reality they don’t understand the concept; it’s just a method that has been invented by forcing things together.
