How do I compare two acid formulas and find out which is stronger? (For seeing if acid will react with a salt)
compare the H atoms to the OH
the more H a solution has the more acidic
the more OH it has the more basic
then there are chemical buffers that keep things close to 7 but that's for organic chemistry :^)
You're asking two different questions. Acid strength has to do with its dissociation, and reacting with a salt is just a separate reaction with the conjugate base and the ions of the salt.
He is asking if I were to give you a diagram of any molecule could you count the H and OH and see which number is bigger. distilled water has a pH of 7 because there are equal amounts of H and OH so it being distilled is irrelevant.
Passed Chemistry with a C with a German teacher who was triggered by me wearing a Russian hat to school erryday and made me take all my tests alone in the testing center.
Never owned a pool.
HCl is Hydrochloric acid. if it begins with H it is always an acid.
the O would combine with the H and make a neutral solution
O + HCl = OH + Cl
What am I reading in this thread
OP, the relative strength of an acid is based on how easily the acidic proton dissociates with the conjugate base. Easier dissociation=stronger acid. HCl will 100% dissociate, whereas CH3COOH will not (only about 1-2% in water at 25 C)
What information are you given to solve the problem? Because you can answer this from several different perspectives, e.g. bond strength between A- and H+
Also when you are only adding Oxygen that just means you are heating the solution
It's called a combustion reaction.
Electronegativity, resonance, hyperconjugation, sterics - all these things affect how acidic a molecule will be in solution and it is not necessarily obvious from a structure how acidic something will be until you have some experience with it. Just learn the 7 strong acids that are usually taught and everything else is weak.
The problems are random acid + salt reactions. I don't exactly remember the rule there and can't look it up right now, but part of it was checking if one acid is stronger or weaker than the other. Couldn't figure out how to check that.
i.e when I want to know if HCl is stronger than H2SO3, then what do I do?
This German teacher thought I sounded like a retard when I warned the class to never mix bleach and ammonia in the toilet.
This is some common core level of techinical jargon
something is acidic if it has single bonded hydrogen
something is basic when it has a single bonded oxygen
it dosn't matter if the field in the holographic universe
Look up some Ka values. HCL won't have one because it's a strong acid. H2SO3 will have one because it's a weak acid.
If you have two weak acids, the stronger acid has a bigger Ka value.
single bounded hydroxide my bad
hydroxide is just the fancy term for OH
>something is acidic if it has single bonded hydrogen
No? Pic related
HCl is a strong acid because it has no oxygen
H2SO3 is a weak acid because the acid to oxygen ratio is lower I can do this all day.
This is a victory for /sci/
Don't worry about it. Mine was a highschool question and there are only some 10 different acids in the tests. Anon gave me a keyword 'Ka' value, so I googled it, found a table listing common acids by strength and the solution is to just memorize what is stronger.
It is if you didn't learn anything in this thread.
That's like planning a vacation by memorizing all of the streets in the county.
Learn the basics first then move your way up the field ladder.
You might as well learn computer programming by reading SICP
>HCl is a strong acid because it has no oxygen
>H2SO3 is a weak acid because the acid to oxygen ratio is lower
You didn't really post this, did you?
>I can do this all day.
And you'd still be wrong.
This guy's got it.
God damn it people. An acid is stronger if its conjugate base form (aka deprotonated structure) is more stable. Compare the conjugate base structures of the two acids you're looking at. Things to consider:
Resonance- more resonance structures, more stable
Conjugation- alternating double bonds, these add stability
Separation of charges- self-explanatory
In the example of HCl as a strong, acid, Cl- is pretty damn stable because its electron shell is full, and Cl is already electronegative as fuck. Also consider the strength of the H-A bond.
