Chemistry Tutorial12.2c: Voltaic Cells Drawing

[suntannedmedal]

Oh you wonderful teacher you! You clarified all the doubts I had on voltaic cells. +1 to you sir, and never stop making these awesome vids!

THANKYOUTHANKYOUTHANKYOU

[MTajvidi]

YOU ARE AWESOME.

[djs162]

Thank you, you just helped me with passing my chemistry test, I love the way you taught it

[DatNigerian]

awesome explanation of a voltaic cell, thank you

[santbonnet1]

you are sooo good at teaching and making interesting something that my other teacher just makes me sleep

[uoakari]

Love the ox and cat impressions.

[gambart2002]

I like your simple explanation. Greet video! Thanks.

[PaulK0512]

This is fantastic!! Best chemistry lesson ever! :)

[Jfrancis221]

hahaha, great vid.. the analogies were memorable .. AN OX

[MsC1eopatra]

Wonderful video! :D Thank you so much!

[ange3357]

Good Lord, is this AN OX??!! LOL you're awesome

[Agentkiller232]

thanks a lot. good explanation

.

[Vangoghbothears]

That was a great introductory video. Thanks for clearing up some murky parts of galvanic cells. Oh, and you're a nut. But in a good way, of course.

[borishazanov]

U R THE BEST!!!!!!!THANK U!

oh my god, this video is so helpful thank you so much, you saved my chem grade!!!

[georgeme01]

Love the video except for one part... If you hook a voltmeter up to the wires, current does NOT travel through a voltmeter. It becomes more complicated than you show here.

[MarkRosengarten]

@georgeme01 It was not my intention to do an introductory course in physics...it doesn't matter HOW the voltmeter works in this video, it's just THAT it works as a load on the current. :)

i like this guy and his videos- these vidios are just as good as MIT's

[richsocaplaya]

the guy looks sooo proud of himself lolllllz check it on 1:02 but, thanks thous, it was really helpful

[MarkRosengarten]

@richsocaplaya It's all part of the schtick. People are more likely to engage with a teacher if that teacher demonstrates an enthusiasm for their subject matter. I happen to love chemistry...wasn't my first choice, I adore Earth Science beyond the telling of it, but when I was young and chose my college major, I made up my mind that I didn't want to teach high school freshmen. Isn't that terrible????

[XxAngelShinn]

my table says Zn has a -0.76 electrical potential not a + ??

[MarkRosengarten]

@XxAngelShinn Sounds like you have an OXIDATION potentials table. Is the potential for Ag -0.80? If so, that's what's happening.

[XxAngelShinn]

@MarkRosengarten huh =/ the title says " Table of Selected Standard Electrode Potentials" I probably didn't change the signs because teh reaction on the table says Zn2+ + 2e- -> Zn -0.76 . so if i reverse teh equation then i probably have to change teh sign as well

[MarkRosengarten]

@XxAngelShinn That is EXACTLY correct. :)

[treblablue]

This is the best! Thank you for the tutorial. I always have trouble drawing voltaic cells but now this makes it all clear!

[tran61021]

i like this guy.

[banquetdrumming]

im your fan mr rosengarten

[thaitanium2005]

best explanation on youtube about galvanic cells,

all the others are great too, but this video makes its all clear,

thank you
