kaitoufion Posted August 6, 2006 Share Posted August 6, 2006 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... 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"...... Can someone please kindly tell me (at least the formula that I need to use) to calculate the percentage NH3???? :'( Thanks so much!!! Link to comment Share on other sites More sharing options...
