Question

How do i mix potassium dihydrogen phosphate and Ammonium tartrate ammonium nitrate to make a clear solutiion , I heated the solution after i had added all the above and dissolved all but the potassium dihydrogen phosphate, And after a while it got clear, but when it cooled down again it precipitated again. How to avoid this, is there a certain order in wich to add things , or are ther other trix i can use ?

Answer 1

If the solution was clear when hot, and a precipitate appeared when cold, it shows that you had reached the saturation limit. The only was of avoiding this is to make the solution more dilute - add water!
