Bronsted-Lowry Theory structure of equations...!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! (1 Viewer)

[natthetubanut]

Just to check with all of you: usually from left to right equations.

: Acid + Base <=> Conjugate Base + Conjugate Acid

In that order?
Does it matter which state its in - will that change the order?
cos I came across a question with answers which does this:
H2CO3(aq) + H2O(l) <=> HCO3- (aq) + H3O+ (aq)

The above equation is the textbook answer.
Hence my question... I know it matters which side the acid/base is on in coparison to its conjugates...but does it matter in WHICH ORDER???
ie. would it be wrong in a test for showing conjugate HCO3- first as the "conjugate base" by B-L definition?

Or is it only when the substance is in a particular state that it can be treated differently? ie. is there some unexplained rule Im missing or exceptions?

help would be much appreciated...

You don't have to put em in order but it probably looks better if you do.

If they ask you to identify the acid/base conjugate pairs it would most likely be in a multiple choice question anyhow. If not, they would have space to right the pair down; they won't ask you to write an equation.

If by some chance they did, then use shapes around the different pairs i.e. square box around acid-conjugatebase pair and circles around base-conjugateacid pairs.

EDIT: And label the squares/circles too, obviously.
