AI Thread Summary
For electroplating copper onto an iron nail using a copper sulfate solution, three 9V batteries provide sufficient voltage for the experiment. The duration for noticeable copper deposition can vary, but it is suggested that within a day, some visible results should appear. To determine the exact amount of copper deposited over time, measuring the current during the process is essential, as it allows for calculations based on Faraday's laws of electrolysis. Estimating the nail's surface area will help assess the thickness of the copper layer needed for effective electroplating.

For a school project, I need to electroplate copper on an iron nail with copper sulphate solution.
How much voltage electricity will I need for this experiment?

With the help of other sources, I now know that 3 9V batteries will do.But I would also like to know approximately how much time will be taken.
Can anyone help me?

Sure thing. I would ask Faraday about his electrolysis laws and Nernst about his equation.
 
If you start the experiment and measure the current you should be able to work out how many grams are going to be deposited per hour assuming the current stays constant for that time. From the geometry of the nail you should be able to estimate its surface area, and therefrom the thickness per gram. How even it is in practice and how thick it needs to be before you would consider it electroplated - how thick it needs to be to be visible i don't know. I'd guess in a day you'd see something.

If you do it come back and tell us!
 

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
