shailene Posted March 22, 2015 Share Posted March 22, 2015 (edited) What will happen when i put 7g of CuSO4 then filter paper, 7g of NaCl, then filter paper, sanded iron nail, and H20. I am really stuck and i don't know how to explain it scientifically of what will happen, and how? And what is the green color in the experiment, and where the gas bubbles come from, what reaction? Thank you so much Edited March 22, 2015 by linaam Link to comment Share on other sites More sharing options...
hypervalent_iodine Posted March 23, 2015 Share Posted March 23, 2015 If this is a homework question, then what do you I think will happen? What does the nail provide a source of and what will that do in the presence of your other two reagents. As a hint, from what I can tell, one of your reagents doesn't do much of anything. Serious question: if you have already done this experiment, why did you perform it before you knew what would happen? This reaction isn't especially hazardous, but you absolutely should not be doing experiments unless you are fully aware of what is going on. That's just plain common sense. 2 Link to comment Share on other sites More sharing options...
shailene Posted March 23, 2015 Author Share Posted March 23, 2015 Is the reagents that doesn't do much of anything NaCl? If so, why is it even there? Link to comment Share on other sites More sharing options...
studiot Posted March 23, 2015 Share Posted March 23, 2015 Is the reagents that doesn't do much of anything NaCl? If so, why is it even there? Sounds like a salt bridge to me. What aspect of chemistry are you studying? Since you are meant to do the thinking for yourself in homework help, the least you can do is order your thoughts. You mentioned little green men (or was it green colour?), Bubbles in what? A reaction what reacts with what(a clue where is the green colour and what colour is the copper suphate, salt iron, water and filter paper?) C'mon describe the experiment properly. State what you observed. State whatever you think about what you observed and whatever questions that raises. It doesn't matter if your statements are right or wrong, making them is the way to learn.

shailene Posted March 23, 2015 Author Share Posted March 23, 2015 Thanks.. I just am struggling to describe what reaction the green color is? what is it Link to comment Share on other sites More sharing options...
studiot Posted March 23, 2015 Share Posted March 23, 2015 Well you have three 'chemicals' in your list and HypervalentIodine has already told you what one of them is for. So what do you think the reactants are? Do you think the green colour is a reactant or a product? Link to comment Share on other sites More sharing options...
Sensei Posted March 23, 2015 Share Posted March 23, 2015 (edited) where the gas bubbles come from, what reaction? Do you generally know how to check which gas is produced in (any) reaction? - if it's exploding after providing source of fire, it's typically Hydrogen (reacting with Oxygen from air). (could be also methane, ethane, and other flammable gas, but they will create CO2 and H2O, while Hydrogen only H2O) - if fire is more powerful, it's Oxygen. - Chlorine you can smell directly (and not recommended/not possible for longer period of time). - Noble gases can be detected by ionization by high voltage. Their spectral lines, thus color of light in discharge tube is different. For others more sophisticated methods of detection are needed.

studiot Posted March 24, 2015 Share Posted March 24, 2015 Would you consider testing the gas with lead acetate paper? Link to comment Share on other sites More sharing options...

studiot Posted March 24, 2015 Share Posted March 24, 2015 John Cuthber No. I Know you wouldn't, but I was trying to get the OP (as well as sensei) to do some work (thinking) Link to comment Share on other sites More sharing options...
