I seem to be overthinking Conjugate Acids and Bases
It all made sense to me (Acid donates H, becoming more electronegative, Base accepts Proton) but then I encountered this problem: What is the conjugate base of H2PO41-? OH- + H2(PO4)1- > H(PO4)2- + H2O Isn't HPO42- the conjugate base? Or am I doing this wrong?
I have a few questions that are on the worksheet I'm doing... First of all, why is this redox reaction Mn2+ + Cr2O72- → Mn3+ + Cr3+ in an acidic solution? I know what redox reactions are but I don't understand why there's acid and base conditions Next, in this reaction, HPO42- + H2O ⇌ H2PO4- + OH- apparently water is the acid and OH- is the conjugate base... why not HPO42- as the conjugate base and H2PO4- as the acid? My last question is, how do you solve this problem? "A solution of a strong base with pH = 13 is mixed together with a solution of a strong acid with pH = 2. The resulting solution has a pH of 11. What is the ratio of the volumes of strong base solution and strong acid solution added?" Thanks in advance :)
In a phosphoric acid solution which of the following is the strongest base? A)H2PO4- B)PO4-3 C)H3O+ D) HPO4- So I know it’s not H3O because it would be a conjugate acid, but idk how to solve it from here the best I could think of is that it might be B because h3po4 is a weak acid and h3o would be the strongest acid in this reaction making making which ever base on H3O side the strongest base so PO4-3 ? Does this make any sense? Edit: another related question The acidic solution of H2SO3 doesn’t contain which conjugate pairs? A) H2O,H3O. B) H2SO3,HSO3- C)OH- , H2O D)SO2-2 , HSO3-
This is gonna be a long one. I've been having difficulties with the logic to identify an acidic salt vs basic salt without calculations. At first i tried using the reactions with water I would identify whether a strong base or acid was present over the weaker base acid. This would help me identify the salt by choosing the stronger one this worked for: KCl, NH4Br, NaCLO, KCH3COO. But this doesn't work for: KHSO3 (Apparently this is acidic but KOH is a strong base vs Acetic Acid (weak)?) so why not basic? Also (Sorry no one has to do all of these) my logic is flawed with: Cu(CH3COO)2, NH4F, NaHCO3, C6H5NH3NO2, NaH2PO4. I think I'm struggling with the concept I know conjugate base/acid is important in this and hydrolysis but every time I use one of these logics I'm messing up on the concepts and its frustrating.
Hi all, https://preview.redd.it/z1ke2fa38sr11.png?width=386&format=png&auto=webp&s=2e816352c489786ab0f2f93dfc98fbb3e25a5ff1 I have a question about the above problem. I know the correct answer is D, the phosphate ion. I'm having trouble articulating why that's the right answer, though, and why the other answers are incorrect. (I do know that A is incorrect because Na+ is not involved in the equilibria at all, and so the concentration of Na+ remains constant). I know that mixing equimolar amounts of NaH2PO4 and Na2HPO4 will form a buffered solution with a pH of ~7.2 (because when the concentration of acid and conjugate base are equal, pKa = pH). Since Ka3 is so small, very little of the HPO42- will dissociate to form PO43-, so PO43- will be present in the solution at the lowest concentration. Will any H3PO4 form, though? How do I think about that "backwards" reaction, and why it does not significantly affect the concentrations of H2PO4- and HPO42-? Hopefully it's clear what's confusing me! Thanks for any help.
Creating a buffer starting from H2PO4.2H2O and adding NaOH ?
Hey guys, I got to prepare 1 Liter 0,05M from the mentioned buffer with pH = 7,4. The pKa in my table has 7,21. So when I add this in the formula, it gives me [Ca/Cb] = 0,646 which gives me Ca = 0,646 Cb How should I interpret this correctly? Ca = the acid H2PO4-, and Cb is the conjugate base HPO4^2- I need to start with the acid and then add a certain volume of NaOH 1M. This means I need to add 0,00108 mol to the solution acid, and create it's conjugate. Unfortunately the answer is 3 mL NaOH and 0,78 grams of the first component. My answer is 1 mL.
Calculating conjugate base concentrations of PO4 in seawater.
There are three dissociation constants associated with phosphoric acid in water. Given these knowns, plus the known total phosphate concentration (1umol/kg), how would I calculate the concentrations of each conjugate base? Conceptually I pretty much get it, but my algebra skills are really rusty and it's tripping me up. Since I know the total concentration, and the Ks, I should be able to rearrange all the K equations and combine them into the sum total, then solve for each conjugate base. But I just can't seem to be able to accomplish this, algebraically speaking. Any help here? [PO4total] = [H3PO4] + [H2PO4] + [HPO4] + [PO4] K1 = 7.52x10-3 K2 = 6.23x10-8 K3 = 4.5x10-13 and so: [H2PO4] = K1[H3PO4]/[H+] [HPO4] = K2[H2PO4]/[H+] [PO4] = K3[HPO4]/[H+] This is surface seawater, so we can assume a pH of 8.1 to find [H+]. Either way, I'm ending up with needing to solve two variables, and I know there's a better way to do it based on some examples, but I'm not understanding the algebraic rearrangements well enough for some reason.
Why is H3po4 more acidic than H2PO4- and HPO42-? I drew the conjugate base and for HPO42- we get 3 O- for the conjugate base so wouldn't the conjugate base be the most stabilized by resonance for hpo42-? Or would all the negative charges by each other repel each other and cause the conjugate base to be destabilized? I'm not sure if I should look at resonance or the repulsion of - charge Thank you!
If 30 micro moles of lactic acid is generated in a 4 ml enzymatic reaction buffered by 50 mM sodium phosphate (pH 7), what will be the final ph of the reaction mixture? Lactic acid pKa 3.86 H3PO4 <~> H2po4- pka 2.12 H2po4 <~> Hpo4(2-) pka 7.21 HPo4 (2-) <~> Po4 (3-) pka 12.32 I have already found the concentration of lactic acid at 7.5 mM the concentration of the conjugate base . (Hpo4(2-)) at 19.08 mM , but the problem is how to plug these into the Henderson hassle back equation . Which pka do I use the lactic acid or the h2po4 <~> hpo4 (2-) ? And what do I plug in as my parent acid in the ratio? Also how does the addition of lactic acid affect the concentration of the parent acid?
The conjugate base of an acid, any acid, is defined as the acid "LESS" a proton, H^+. The conjugate acid of a base, any base, is defined as the base "PLUS" a proton. Phosphoric acid, H_3PO_4, is the parent acid. If it loses a proton, H^+, we conserve both mass and charge, and H_2PO_4^- results. And what is the conjugate base of this beasty?
