A negative number squared becomes a positive number, so -1^2 = 1. So you basically have 0.5 ( (0.1 x 1^2) + (0.1 x 1^2) because the -1 becomes positive 1 when you square it. I know this is a late response but I hope this is helpful for someone in the future!
If the ions are +\-1 then the ionic strength is the same as the concentration of the salt. The identity of the ion is not considered here, just the charge.
If Ionic Strength is 1.1M how much would the activity (active mass) be? I've been taught that when Ionic Strength tends to 1 then Activity tends to 0. Am I wrong on this?
When ionic strength goes to 0 then the activity coefficient goes to 1. Increasing the ionic strength will lower the activity coefficient. The activity coefficient affected differently for each ion. Higher charges, and smaller hydrated radius ions deviate more from 1.
Thank you Good man.
Way better than Khan Academy! I ace my exam after watching these videos.
Nice tutorial Dr Wilson
Thank you, I’m glad it was helpful.
great fountain pen
Sheaffer Viewpoint Calligraphy Fountain Pen seems to work well. I have also been using glass dip pens.
عشتتتت 🎉

Good
very clearly
When I input 0.5 ( ( 0.1 x 1^2 ) + ( 0.1 x -1^2 ) ) it says the answer is 0.
(-1)^2

How do you know how many sulfate in every Sodium sulfate
Based on the charges. Sodium has a +1 charge and Sulfate has a -2 charge. There will be 2 sodium for every sulfate.
Super machi 👌
Explain. Out uni univalent electrolytes like nacl and kcl

Hi, how does changing ionic strength increase yield
Big fan sir😍😍😍😍
Thank you!
