Question! I was reading that some alkaline cells contain potassium hydroxide as the electrolyte. i also found out that potassium hydroxide is the electrolyte used in alkaline fuel cells, the first one made by Francis Thomas Bacon used potassium hydroxide. Have you seen or heard about someone making a fuel cells using the contents from alkaline cells?
Questions. So instead of Pt electrodes we instead used Li metal oxide and graphite for the electrodes. Would external power source orientation, which in this case the battery, matter? Would you place the positive end of the external battery souse on the Li metal oxide or graphite? Finally if you were to flip the external battery source to where the positive end is now in contact with the graphite would it still charge?
If you're dealing with a mixed open system as we have here, and your electrodes are non-reactive but conductive, then I don't see how it matters which side is connected to which electrode, however if your electrodes are chosen specifically for how they interact with the anode or cathode, OR if your system is separated into half-cells, then yes, the orientation absolutely matters
I'm unsure of exactly what you're asking. The electrodes are drawn and explained in the video's example. You can see both the anode and cathode present in the full depiction around 9:30. They are inert and present in the same container with no fear of a spontaneous reaction happening outside of them.
Just to check if I got that right haha Basically, in here, the (-) side of the cell is giving electrons to the +ions by the cathode, and the (+) side is receiving electrons from the -ions by the anode. The cathode is reducing ions, and the anode oxidizing them. In the galvanic cell, the cathode is still reducing, but it's reducing what exactly, the anode? So, the metal in the cathode goes to the ion form, getting itself oxidized while reducing the anode, which is oxidizing the cathode while reducing the +ions in the other solution? I am a bit lost in this one Is everything right?
Mam can you plss make a video regarding how battery work like when we connect anode to + terminal of battery why anode gets positive charge and mam how battery provide current in circuit plsss mam i am very confused!!... ❤❤❤❤❤
Copper has a higher reduction potential than zinc. That means, in reaction with zinc, it will be reduced at the cathode while zinc is oxidized at the anode.
This video seriously deserves more credit, it is so simple and concise, thankyou so much!
Glad you liked it and you're so welcome!
what a simple and logical explanation, thank you!
You're very welcome!
The phone analogy really helped me to grasp how these two cells are intertwined, thank you
So glad to hear that! You're welcome.
Very Nice, it helped prep for my test!!
Great to hear that, fingers crossed you reach your goal!
The formating and colors were so helpful.
So glad you liked it and found it helpful!
Wow! You answered my question perfectly!! Thank you so much
You're so welcome!
Thank you
You made it so simple to understand
Thank you so so much
You're so welcome! :)
this was SO helpful! thank you!!!
I'm so glad! You're welcome!
Thank you for your clear cut lectures!
You're welcome! Happy to help.
Found a great video loved ❤ your content 🎉
Yay! Thank you!

I'm not familiar with this
Can you make a vedio on diffrence between galvanic and electrilytic cells
I'm actually working on it right now and hope to publish in May.

great video! but what would the electrodes be in this example?

Is everything right?
I'm working on a comparison video that goes into detail about the differences. I hope to have it out in a few days
@@Leah4sciMCAT Already got my exam haha but thanks, I will check it
Keep it up.Thank you
You're welcome!
Love it..❣️ keep it up
Thank you! I plan on it. :)
Life saver
So happy to help!

That's actually my very next video which I hope to publish in a few days. Make sure to check back by Tue/Wed so you don't miss it
Thank you so much! Will you be filming a video on the differences between voltaic and electrolytic soon?
@@Leah4sciMCAT thank you!! ☺️
I'm working on it right now, a bit later than planned. It will be posted here on my channel as well as my website leah4sci.com/electrochem
Thankss for the vdo
You're welcome!
I thought zinc is more reactive than copper
Copper has a higher reduction potential than zinc. That means, in reaction with zinc, it will be reduced at the cathode while zinc is oxidized at the anode.
