THIS WAS SOOOOOOO CLEAR!!!! I was seeing every video for this topic but they weren't that clear. After seeing this, I feel like I got everything!!!!!!!! tysm
Dear Cognito, At 3:54 you said that the hydrogen ion concentration decreases by the factor of 10 to 3 times. This made me think 10 X 3 instead of 10^3, so saying "10 to the power of 3 times" would set a clearer understanding. Kind Regards, Shrish
Have you ever done a video on bearings? Thank you soo much your the best teacher that teaches chemistry and my teacher at school but I get confused if I watch you and my teacher teaches us
that's not his fault lol? maybe you should watch a channel that speaks your language instead of watching an English based channel and complaining that he doesn't speak slow enough
