I have a bachelors in bio and a master's in biomedical sciences and throughout my lifetime as a student, not one single professor has explained this as easily and thoroughly as you have. Thanks!

We used galvanic protection to prevent pipeline corrosion in petrochemical refinery. We measured the current as part of inspection to make sure the buried hydrocarbons pipelines were prevented from corrosion. We buried sacrificial anodes. This is one of the responsibilities of Inspection Engineers working on pipelines in petrochemical refineries. Inspection Engineers are generally Process Mechanical Engineers.

Excellent explanation! I didn’t know about the term “intrinsic positiveness” until now. This is another way of looking at the values of reduction potentials and decide which metal gets oxidized and which one is reduced.

@sciencesimplified3890 Жыл бұрын

Just FYI, intrinsic positiveness is just a term I’ve made up to explain this concept lol… in my mind it really helps make this topic intuitive and make sense and I think will help for all intents and purposes you’ll come across moving forward!

@EthanMaxwell-bo4ui 5 ай бұрын

gotta be illegal how simple you made this

@anthoniaaralu4023 Жыл бұрын

for 6:05, how is Au(gold) getting oxidized when it has a higher reduction potential? I think I might be getting the concepts missed up.

@TheFireMage100 7 ай бұрын

Studying chem at degree level and Im not a huge fan of the "positiveness" idea personally. Makes more sense to say "more readily accepts electrons" in my head. Besides me being weird with that one thing, loved absolutely everything else. This is one of the concepts I just couldnt understand for months no matter who tried to help me and youve managed to help me understand in literally just 20 minutes

@pranaymaniar1468 3 жыл бұрын

wait i think you mixed up the positive and negative sign? wouldn’t the electrons go from the negatively charge anode to the positively charged cathode

@sciencesimplified3890 3 жыл бұрын

Can you tell me specifically what moment in the video you’re confused about

@pranaymaniar1468 3 жыл бұрын

@@sciencesimplified3890 yes, the last 30 seconds show the flow of electrons from anode to cathode. however, isn’t the cathode positive in a galvanic cell?

@sciencesimplified3890 3 жыл бұрын

I see... so what I was showing is how negative potential builds up on the right side (because negative electrons are flowing in that direction)... so this would minimize the thermodynamic favorability of this reaction as the right side builds up negative charge due to accumulating negative density from the electrons.. therefore you need a salt bridge to mask and ameliorate these electric potentials... so I was illustrating why we need salt bridges to allow this battery to remain spontaneous

I don't know if "intrinsic positiveness" is much less confusing. I prefer "electron affinity," because then I don't even have to remember that electrons like positive charge to know where they're headed. The one with higher electron affinity wins!

is there a video on the electrolytic cell?

@rachel39321 Жыл бұрын

ah but is the cathode where reduction takes place or does the cathode itself gets reduced? as in is the cathode a reducing agent or oxidizing agent?

Hi Sir! May you provide us a clear explanation on how the copper and silver ions initiate the flow of electrons through the wire?

As well as why is it necessary to place the metal electrodes in solutions of their own ions?

So we CAN make gold.

@sciencesimplified3890 3 жыл бұрын

Haha yup! Well at least turn soluble ionized gold into solid gold haha... what’s more interesting is we can shoot neutrons at mercury atoms and this will form an unstable mercury isotope that’ll beta decay into real stable gold atoms! This is 100% real and backed by science! Only problem is this entire process is magnitudes times more expensive than just buying plain old gold from the pawn shop haha
