If I want to 18K gold electroplate a carbon knife (opinel), can I use as anode a piece of 18k jewelry, and, as I don't have a gold solution, can I use simple sodium bicarbonate as my electrolite?
I really like your breakdown, but isnt the copper anode "racing" to replace the ions in the copper sulfate solution vs the cathode? The anode is more of a replacement of the copper in your electrolite right?
measuring the anode for copper plated amount, does not work. In most case the "acid" bath will dissolve the anode even if there is no current. This is why we remove the anode after plating. The amount plated, and amount added to the electrolite both need to be taken into account. I am refering to the video around 6min. Perhaps this is correct under the right circumstance, but its a little more complicated if your using this video to get into electroplating chemistry.
@@madebyrasa keep in mind these videos are meant for students writing chemistry exams and not for practical application. The way he’s explained it here is parallel to my textbook. Like with most things in school, the theory explained in textbook is either null and void in real application, or needs adjustment before it can be practically applied. Edit: the reasoning for this is in theory we do not look at external forces acting on a system. I.e. we often negate air resistance or friction in physics, or in this instance we negate the effect of corrosion on the substance. So assuming that the only cause for loss of mass from the anode is ion transfer, and not the acid solution corroding the anode, then his method of measuring makes sense. This is merely high school chemistry so I’m hoping they expand on this and make it more practically applicable at college level.
@@avationmusic sure, I understand that, and it only applies if electrolyte has no copper in it. And this would not work. I find it annoying that the text book misinformation is "standardized" in your view. These questions should be discussed within the sourced fields. It's funny how wording something different fixs everything, and portrays reality. It's also funny, that this question could have bleed written well in the past(which it has) and with simplified results loosing any practical meaning. Let's base these questions on replicating observations and data, not simplified "standards" based on historical textbooks. after all, it's science and not law.

Really dude, you've helped me a lot with a lot of your explanations and all of your videos, and to be honest your content has helped me a lot.
this really helps...keep it going
bro i got 98 percent in my mocks cause of u i literally love you yes homo
😂
I actually want to try some at home electroplating, I just don’t understand if less amps but more time is better than more amps in less time
I wonder why the electron in the circuit is moving out from the negative end of the power source as you drew in 3:16?
Thank you

Dang! It suddenly makes sense!
Thanks a lot
Thanks a lot❤️

i sugest to instead weigh the cathode before and after.

why cathode is removed when current is on???
How do you know that copper is 2+? Couldn't it be 3+, too?
Sound is very low
maybe increase volume?
Thank you
Thank you
