What You Need to Know About Isoelectric Focusing | MCAT Content

[@hanaeelkholti7168]

The only one on youtube that i do not need to do x2 ! you are awesome thanks !!

[@vanessaesmeraly5919]

You have made this concept so simple to learn!! Your video is the only video that helped me FULLY grasp the concept and now I feel more confident tackling this topic in questions. THANK YOU!!

[@EightfoldMCAT]

Glad the video helped. I remember feeling so lost on this topic eventually things clicked but it was definitely a struggle for me too.

[@jonathanhermes7685]

Thank you SOOOO much! The "anode/acidic/positive terminal" trick and remembering isoelectric focusing uses a power source and is therefore an electrolytic cell also helps me remember that galvanic cells comparatively have a negative charge at the anode!

[@EightfoldMCAT]

Glad the trick helped!

This series is great, one note though, a galvanic cell has a negatively charged anode and a positively charged cathode, the addition of a battery to an electrochemical cell to complete the non spontaneous reaction is what causes the sign to flip on the anode and cathode

[@TheBivensemily]

From wikipedia "The anode is the electrode where oxidation (loss of electrons) takes place (metal-A electrode); in a *galvanic cell, it is the negative electrode*, because when oxidation occurs, electrons are left behind on the electrode. These electrons then flow through the external circuit to the *cathode (positive electrode)* (while in *electrolysis, an electric current drives electron flow in the opposite direction and the anode is the positive electrode).* The cathode is the electrode where reduction (gain of electrons) takes place (metal-B electrode); in a galvanic cell, it is the positive electrode, as ions get reduced by taking up electrons from the electrode and plate out (while in electrolysis, the cathode is the negative terminal and attracts positive ions from the solution). In both cases, the statement 'the cathode attracts cations' is true."

These videos are so good. Thanks!

[@vswchoe19]

amazing video! Thank you so much =]

[@sunairaahmed3720]

HI! This video was great! Can you make a video about mass spectrometry next for the MCAT lab techniques? I was having trouble on that :(

[@EightfoldMCAT]

Glad the video was helpful! Mass spec is on my list. I hadn’t planned on doing that specific lab technique for awhile but I’ll move it up.

[@itsmatrix1223]

Awesome video! One question though, why would an ANODE attract anions in a Galvanic cell if the anode is considered negatively charged ?

[@SP-jz5dv]

my understanding is that the anion is always oxidized, so it always gives up e- -> so it must be +ly charged. I dont have a good explanation for where the + and - conventions come from - but those might be different from the charge of the anode vs cathode.

I love you

[@Kencan254]

Slow down your mouth. You are hard to follow because you talk too fast.

[@EightfoldMCAT]

I definitely do end up talking a bit fast in some of these videos. I have gotten similar comments on other videos and when I get started making videos again I am planning on being more mindful of how fast I’m talking. If you find the videos a bit to fast YT does have an option to slow them down so they are at a better speed for you.

[@Kencan254]

@@EightfoldMCAT Thanks, for the suggestion. Yes, slowing down the speed helps. When are you planning to post more MCAT videos? My exam is on September 13th, 2024.

[@zoecarwardine5157]

You talk way too fast!

[@EightfoldMCAT]

I have tried to address that on my more recent video but it is still something I am trying to figure out. If you like the way I teach but find the pace too fast you might try watching the videos on 0.75x.

[@nilazazai5554]

He is amazing even when he is fast 🥰🥰

[@diegomora9202]

that's what she said@@nilazazai5554

[@ICantSeeYourRepliesDickhead]

Nah he's got the perfect speed. I watch him in regular speed vs everyone else on x2 or 1.5x
