Wait, i think i realized something. All along i thought i had to replace A with OH but now i get what's going on. I'm supposed to compare the overall H3O+ concetration with the OH- concetration which is only produced by the water's self ionization, which as a phenomenon, is known to be quite...

I am familiar with these but yes, i usually tend to try to understand something and its origins instead of simply accepting it. It helps me understand more

Is that other source the water solvent?

i forgot that OH was substituted in A. So it's Kw=[H3O+][OH-] ?

Isn't the water ion product notated as Kw? Isn't it an equilibrium constant?

What exactly does that mean?

That's what i thought of regarding the second answer i came up with. However if that was the case, wouldn't the hydronium molarity be equal to the hydroxide one? In the book it says that this is not the correct answer. I didn't think of the ion product. If i substitute that in then i get...

I think the equation is HA->H+ & A- . Obviously 1 mol of HA gives 1 mol of H+ and 1 mol of A- so the mole number of H+ and A- are equal. Since there is no change in volume, the concetrations of H+ and A- should also be equal. Therefore [H3O+]=[A-]. What confused me about the original question...

This question says: An HA weak acid solution with a molarity of 0.1M is dissolved in water. In the new solution, is the molarity of OH- greater than the H3O+ molarity, or the opposite? Or are they equal? I came up with two possible answers: 1. [H3O+]>[OH-] because there are no hydroxides...

Sorry for being late, i believe pH is derived as the negative logarithm of the acid's molarity (moles of H+ divided by the solution's volume) I suppose that the acid is being dissolved in the water, releasing H+ ions. This might be wrong (aswell as the H+/V derivation i mentioned in the...

acid= substance with pH<7 solution of highly acidic HA= a highly acidic substance is solute in water?

The question says: A solution of highly acidic HA is given, with a molarity of 1M. Is it true that [A-]>[H3O+] or not? I simply don't understand why the hydronium is mentioned and i don't know how to find the molarity of these two individually.

I used the two equations i listed by using B1=B2 and by doing that i ended up finding that N1/N2=λ. However i am not sure if that's the correct answer as λ is just a variable and not an actual number. Do you think it has to be an actual number or is it not really necessary?

aaahhh! Well, no. The nickname HazyMan is related to an old favourite game of mine

...what?
