How interesting is water? Well very interesting when you watch this short video on Kw. Find out why water plays a role in pH and what a Kw expression is. #amazingwater

Thanks It cleared all my doubts regarding Kw that how it's a constant!👍

Cool. Although you must love chemistry more than physics now?? Ha ha. Please share, the more people use this channel the better! 😀

Wow! God Bless you and Mary protect you! You are such an inspiring teacher. I love how you were so humble and took your time to break things down from base 1 to me. Some people like crash course are just horrible at doing a good job at teaching, to them its a speed competition. You are smart, dedicated, humble and awesome! You explained this concept so good. We are in need of your channel because you are actually explaining the concept behind the calculations. Once students learn the meaning of something its no longer forced learning. Thank Your Sir!

Why does that assumption matter so much? When calculating Kc are we assuming that the concentrations of H and OH- have a negligible increase since [H20] has a negligible decrease?

Thanks! i have a question... Is Kw consistent as 10*-14 in 25° only, or will it change by changing the temperature?

@tonystarkdeservedbetter Жыл бұрын

I'm sorry for answering this 2 years later but I hope this can still help you or anyone else. The reaction H20 - - - - - > H+ + OH- is an endothermic reaction therefore when temperature increases the equilibrium shifts to the right hence the concentration of the products increases. as kw is directly proportional to the concentration of the products it will also increase. So basically although it's a constant it will vary with temperature, an increase in temperature will increase the value of kw and a decrease in temperature will decrease the value of kw. Hope this helps :)

Why always 10^(-14) at 25?

@oneinabillion654 5 жыл бұрын

Hi, I want to ask. Why is PH = - log [H+] and not - log [OH-]

@dollsfunandaestheticgirl511 3 жыл бұрын

PH =-log [H+] for acids POH =-log[OH-] for bases
