Calculating pH of strong acids

Показать описание

pH - a part of science you have known about since the age of 10 probably. But it is not until A Level that you actually have to calculate pH and know what pH actually means. This video shows you complete with calculations!

The fact that all your videos are in order it makes it so easy to follow and understand! cheers :) I hope all these comments aren't annoying you :p

It helped me a lot and you explained it really well. However you may find it use full to change ur camera angle maybe even if you got a large card board box to prop it on something stable. You could also buy a tripod. I just wanted you to now that I am only telling you this with the greatest respect intended.

7 years on and these videos are still extremely helpful. what a lad <3

so calculating H+= shift log ph ? Both me and my friend tried shift log 12 and we both got 1x10^12

You Sir are a LEGEND! Keep up the quality content

Would you be able to do a video on The Arrhenius Equation from the thermodynamics topic? It's for AQA and I'm really struggling!
Your videos helped so much in AS

thank you for your beautifull lessons, i have a question please : i
understood that for strong acid [H+]=[HA] since complete dissociation
occured, but to be precise isnt [H+] = [HA] + 10(-7) ?, where 10(-7)
is the concentration of hydronium ions already in water ?, is my logic
true ?, are we ignoring this 10(-7) since it is small number ?...thank
you

I have my a2 chem exam in Jan, and I am starting to prepare now 😰😷, is there time to get an A now ?

its not a related question, but do you play cricket? since you are english?

You are like Sheldon in Big bang theory, but nice videos, very helpful

I thought that after the first h+ is released in h2so4 it becomes a weak acid (hso4-) doesn't that mean we use the Ka expression for it after the first dissociation ? Cheers for the videos btw

Also what order do you recommend watching it in, to learn the topic from scratch?

Can you do a video about calculating the ph of an acid after dilution?
These are the questions I'm stuck on-
a) addition of 250 cm3 of water to 50 cm3 of 0.200 mol dm-3 HNO3
b) addition of 25 cm3 of water to 100 cm3 of 0.100 mol dm-3 H2SO4

ANSWER OF 3RD QUESTION IS WRONG its 1x10 to the power -12 not 6.30x10 -2
