Can someone work out this concentration PLEASE IM DYING (1 Viewer)

[cheesynooby]

so ka=[HCO3][H+]/([H2CO3]-x)=x^2/(x-x) that's a div 0 error fml

well [H2CO3] final approaches 0 so Ka approaches infinity which is kinda necessary cuz Ka is so high compared to the values for [HCO3]^2 (like 10^-28)
(yeah excel probably just cant comprehend these numbers)
best justification for a nasa supercomputer

bruh i need a nasa supercomputer to do the fkn calculations wtf

what is chemistry even about at this point?

i dont even know anymore chemistry was my favorite subject until 6 hours ago when i realised its just a whole lotta butfkry

 

[C2H6O]

Ok can someone just answer whether or not its possible that with a ka of 2.5*10^-4 to have [H2CO3] approximately equal to [HCO3-]?

 

[C2H6O]

oh wait does it kinda make sense that if [H2CO3]initial is a tiny bit bigger than [HCO3-], then ka = a tiny number * a tiny number /(a tiny number-a tiny number that’s an extremely tiny bit smaller) = a very tiny number/a near 0 number = a small ish number (2.5*10^-4)?
