Recently I've done an experiment and we are required to determine the percentage NH3 in the complex by mass.

 

I had no problem doing the experiment but stuck in the calculation part :-(

Really hope someone can help me here!!! >.<

 

The experiment was done by titration, the complex we used is... (CuSO4*5H2O + H2O + NH3 + ethanol + acetone) - sorry I don't know how I should call this @.@ But those are the things we used to make that complex... :embarass:

 

First I dissolved 0.2g of the complex with 25mL H2O, & 31.05mL of standardized 0.1M HCl was used to titrate it. Then we are required to find "%NH3"...... :confused:

 

Can someone please kindly tell me (at least the formula that I need to use) to calculate the percentage NH3???? :'(

 

Thanks so much!!!

as this is evidently Homework help, we`re not here to give Direct answers, but what I Will tell you is do a few searches for Tetramine Copper (II) Sulphate :)
