Please don't ever stop making videos I spent hours today trying to comprehend my teachers powerpoint and almost gave up on my exam tomorrow. I immediately understood EVERYTHING just from watching your video just one time. Thank you!!!!!

I think at 4:47 sir. Think the power of 10 should be -13? I tried 10 to the power of -14 it gave me 13.5

I found a short cut to this. Use the simple formula from the beginning of the video pH= -log [the given concentration] then solve. Then subtract your answer from 14 and you will only be about .1 or .2 off it i is a lot quicker, try it! :D

i did that too but got a different answer then him.. so confused. did you get the same answer?
@JacoFreezem6 жыл бұрын
resoof his way works I think he accidentally put -14 on the second step because I put -13 just to see and got the same thing he got.

On the 3rd example I do not know why I can't get the concentration correct. Not doing it right on my calculator?

Hello,in the first problem i kept trying to calculate the 2 times 5.7 X 10 to the -7th a couple of times and i kept coming up with 1.14 x 10 to the -6th. I put it in like this: (5.7 X shift log-7(2)) =1.14 X 10 to the -6th. I cant see how you got 1.14 X 10 to the -9th,can you plz explain.Thanks!

I think you meant to put a -13 in the last step because then you come out with 12.5. -14 gives you 13.5

How is it possible that a base have acid character, third one has ph value 5.95

So the 10^-9M Mg(OH)2 solution is in fact *acidic*???

What is the value of log?
4 жыл бұрын
"log" has no value. Log is short for logarithm (of the base 10 in this case). In simple it works as follows: log (10^x) = x e.g. log (1000) = log (10^3) = 3 ^ is mark for upper index

If you want to know, how to properly and *correctly* calculate the last example with dilution of base, go to this link: www.researchgate dot net/post/What_is_the_pH_of_very_diluted_for_example_hydroxide#view=5dfc383f2ba3a1661305ce8c Because obviously base cannot have pH lower than 7.

@ramzilodge76437 жыл бұрын
Example 3 is conceptually incorrect. With a concentration that low of a base how did you end up with a pH of below 7. Makes no sense. There is a another calculation that must be used when concentration is that small. Educate yourself.
@ericksonhangula80856 жыл бұрын
Thats correct. looking at it , mg(oh)2 is a strong and should have a ph greater than 7. can one help me how to calculate that
