Homework Statement Write separate equations for each potassium salt (KH2PO4) dissolving in water and for the ionization reaction of the weak acid anion that each of these salts contains. Homework Equations None The Attempt at a Solution I just needed to clarify when it dissolves in water do...

i understand the equation but I am not sure how to determine H30 concentration and HA- Concentration with just the acid dissociation constant for hydrofluoric acid

It simply states that the acids donate H+ and bases accept H+

Yes, but I don't see the correlation

Can you explain what you mean

I didn't really get the question either

So is it just the equal to the dissociation constant of the HF acid itself or something

If I'm given the dissociation constant for HF, how would I find the dissociation constant for F-? Thanks in advance.

naturally, i'd want to pick the smallest value which is 0.000125L, but its not what i got

but the multiple options are 0.000125L, 1250ml, 125 ml, 50,000ml so please advise

The question should say How much 4.00M of HCl is required to make 100ml of 0.200M HCl? Oops typo, I meant to say (4.00M)*(xL) = (0.200M)*(0.100L)

I just need confirmation if i did it right or i messed up on something Thanks

Homework Statement How much 4.00M of HCl is required to make 100ml of 0.400M HCl? Homework Equations M1V1 = M2V2 The Attempt at a Solution Its (4.00M)*(xL) = (0.400M)(0.100L) I think its 0.005L but the possible answer (multiple choice) say otherwise...

I think I got it. It has to do with the placement of lone pair of electrons on the central atom. Thanks

I am considering the VSEPR to be "ideal", sorry for any confusion
