Re: Ka and Kb
Ka is the acid dissociation constant and Kb is the base dissociation constant. The lower Ka for the acid, it indicates that it's a weak acid that holds tightly onto the proton. The weaker the acid, the stronger the base. The stronger the base, the higher the Kb. The weaker the acid, the lower the Ka. So they move in that way.

Re: Ka and Kb
Hi! To add on to the previous post, Kb can be calculated from Ka and vice versa using the formula Kw = Ka * Kb. This formula also shows the inverse relationship between Ka and Kb. I hope that helps!

Re: Ka and Kb
Ka and Kb are the acid and base dissociation constants, respectively. The higher Ka and Kb are the stronger the acid and base and the more it dissociates. You can find ka if you know kb by plugging into the kw=ka*kb equation.

Re: Ka and Kb
Hi! Ka and Kb are the dissociation constants for acids and bases.The stronger the acids and bases, the higher the value is for Ka and Kb, and vice versa. You can calculate the value of Ka and Kb by using this equation and solving for the constant you need, if you know the other: Kw = Ka * Kb

Re: Ka and Kb
I believe the simplest way to get Ka and Kb is to remember that for any Ka, the product of it and its corresponding Kb should equal Kw (10^-7), which is the Ka & Kb of water (neutral).

Do we need to know about Kb for the final?
