Complete the Bronsted lowry reactions
HPO42-+H+<-->
HPO42-+OH-<-->
HPO42-+H+<--> H2PO4^-
HPO42-+OH-<--> PO4^3- + H2O
if bob is wrong i dont want to be right
it's actually right
Bob really was correct those are both the correct answers
To complete the Bronsted-Lowry reactions, we need to determine the products formed when the acid (HPO42-) donates a proton (H+) to a base (HPO42-) or (OH-).
For the reaction: HPO42- + H+ <-->
Here, HPO42- is acting as a base and accepting a proton (H+) from an acid. When HPO42- accepts a proton, it forms its conjugate acid, which is H2PO4-. Therefore, the reaction can be completed as follows:
HPO42- + H+ <--> H2PO4-
Now, let's move on to the second reaction: HPO42- + OH- <-->
In this case, HPO42- is acting as an acid and donating a proton (H+) to a base (OH-). When HPO42- donates a proton, it forms its conjugate base, which is PO43-. Therefore, the reaction can be completed as follows:
HPO42- + OH- <--> PO43-
So, the completed Bronsted-Lowry reactions are:
HPO42- + H+ <--> H2PO4-
HPO42- + OH- <--> PO43-
