I love how simple yet thorough your explanations are.

I've watched almost every video. He's amazing! So grateful. :-)

[@surfergirl22330]

also a classic trick is taking the number that is multiplied by the 10 (4.9) and moving the decimal point over to make .49. Then you take the exponent (7) and subtract the decimal, 4.9 to get ~6.5 which is normally "close enough" on the MCATs

I like this trick! ( 7 - .49 for those confused)

[@miguelbarrera4383]

I was looking for this trick I totally forgot it I was doing 4.9 + 0.7 but its actually 7-0.49 thanks

[@mrbrapids718]

I could kiss you lol thank you so much

[@Padayonlanggid]

Hi just wanna ask how did you come up with 4.9X10 to the power of -7? Is confused 😅 thank you!

[@pritishsahoo7830]

dude you are the man

[@taylormendenhall5938]

How do coefficients in a balanced equation affect the formula for solving pH for a weak acid? Or do they not affect it at all?

[@jannicesalazar386]

in the end, you would make the coefficient the exponent and solve for the concentration

You're a life saver 👏👏

Where did you get the 1*10 ^-6 and 1*10 ^-7?

[@ejeifjrjeicjrkwoejcjf]

4.6*10-7 is between those two values, so we can approximate the pH by taking the -log of those values

[@naimabibi6446]

kelly thai but how is it between those two ?

[@ejeifjrjeicjrkwoejcjf]

@@naimabibi6446 0.0000001 < 0.00000046 < 0.000001

[@naimabibi6446]

kelly thai wow that makes so much sense thank you so so much !

[@lionelh7217]

why Ho2^- and not, H^+ + OH^- ?

[@ownitervi241]

Made it worse. 😩
