I have a test tomorrow on acids and bases tomorrow. I understand most of the material except for the acid/base dissociation constants. I think we may have skipped a chapter and that's why i don't know this stuff so well.
Please show me how to do this.
A .1M solution of formic acid has an equilibrium {H=} at 4.2*10^-3 M. HCOOH -->H+ + HCOOH-
What is the Ka of formic acid?

I my sleep-deprived state of mind I was nt paying attention ot my math.
Chemistry, I never finished that subject but it still is encouraging to see mathematics involved in it. I wish I could study some more about what this equation is symbolizing. All I really remember from chemistry was about acids, alkelines and pH balance. Like 7 would be like the water we drink and 6 would be in the acid range for the soaps and shampoos we use. If I remember the range is 1-12; 1 being complete loss of any cohesive compound, 7 is the balance point, 12 being the alkelitic point of cohesion. With both, that is how human beings are held together and function with chemical brain activity and the main reasons that we are able to be born and die. It's when the alkeline fails and the acid takes over or the acid fails and the alkeline takes over that we begin to find ourselves dying. ie hyperventiliation which produces acidosis in the blood. Drowning produces the similar types of effects. Of course, all of this is just a waist of time to our poor host who's having to read all of this and getting more frustrated as these words keep on dredging on and on and on...and on and on. Ganbatte kudasai! :P
