Copper Sulfate Pentahydrate experiment, help please? My science project specifies me to make seed crystals of copper sulfate. We must use the powder form to make seeds. There are two types of copper sulfate pentahydrate; one is granular form (small seeds), and the other one is powder form. We must produce crystal seeds from copper sulfate (powder form). We are not allowed to use the granular form, because it forms seeds on its own already. 

Steps I have taken: 


I saturated 50 ml of distilled water (room temperature) with copper sulfate pentahydrate (powder form). 
I added about 15 ml of purified sulfuric acid to the mixture, so it prevents the hydrolysis with water.This purified sulfuric acid I got from boiling battery acid. I boiled about 50 ml of batter acid (sulfuric acid mixed with ionic water). I waited till it reached about 15 ml (water evaporation). The fumes were getting strong at that stage. I'm not sure if purified enough. 
I then again mixed more copper sulfate to the mixture, and stirred it very well. 
I put the china dish (mixture) on a hot plate, and waited for it to reach crystallization point, while stirring it very well. 
5 I know the water has to evaporate for the mixture to produce seed crystals. I waited for the mixture to evaporate about to 20 ml. 
I had no results. 


I'm not sure what I'm doing wrong. I'm doing my project according to this video which I found on youtube. It is a very short video, and my main problem is the sulfuric acid part.

Help.
Frankly you're going about this all wrong. First you want to exploit the difference in solubility of the salt in hot water versus cold water. 

Copper sulfate's solubility is 32 g/100ml water at 20 C, and 114 g/100ml water at 100 C. 

2-3 drops of sulfuric acid is all that is needed. You're just trying to prevent the formation of $\ce{Cu(OH)2}$ or $\ce{CuCO3}$.


  I'm not sure about battery acid. I assume that you're using new battery acid, not actually from an old battery. So the sulfuric acid will be a little less concentrated. Use 5-6 drops instead of 2 or 3. 


After you make a saturated solution of the copper sulfate (aim for 100g /100ml water) in hot water, let it cool slowly and don't stir at all. Stirring will promote nucleation of many small crystals. 

To get a really large crystal you'd make a saturated solution at room temperature, filter it, and add one of these seed crystals. You'd then let the water evaporate over weeks very slowly.
