Why is the Brønsted-Lowry definition of acids more general than the Arrhenius definition?

A Brønsted-Lowry base accepts H+ ions.

∙ 13y agoThe difference is the same as for any acid/base comparison: they are chemically 'opposites' or 'mirrored' conjugate compounds.
An Arrhenius acid produce hydrogen ions (H+) in water while an Arrhenius base produce hydroxide ions (OH-) in water.

∙ 12y agoAll Arrhenius acids are bronsted -lowry acid. For e.g. HCl
HCl-----> H^+ + Cl^- According to Arrhenius it is acid since it gives H+ ion
Also
HCl + NH3 ---------> NH4^+ + Cl^- Acoording to Bronsted-Lowry theory HCl is acid since it donates proton.
But according to Lewis theory acids are lone pair electron acceptor. Thus, HCl is not Lewis acid.
We now conclude that All Arrhenius acids arebronsted Lowry acid but not lewis acids.

Wiki User
∙ 12y agoBecause some acids contrinute H+ directly to the base so that H+ will not be found in solution.
Wiki User
∙ 14y agoBronsted and Lowry saw that some acids do not create H+ ions in solution but that all acids donate a proton in a reaction with a base.
Wiki User
∙ 14y agoBecause some acids contribute H+ directly to the base so the H+ will not be found in solution.

B-L acid = proton donor
B-L base = proton acceptor

What is the common constituent in all acid solutions?
It's the hydrogen ion: H+The answer above is only partly true. First of all, in any aqueous solution, it is hydronium, H3O+, and not the hydrogen ion that is found. Secondly, this answer assumes the Arrhenius definition (or Bronstead-Lowry definition) of acids. The most general definition of acids is the Lewis definition, which states that acids are electron acceptors. This has nothing to do with hydrogen or hydronium, and using this definition, an acidic substance may not have any H+ or H3O+ present. Using the Lewis definition, there is no common constituent in acid solutions in fact!
All acids ionise in water to give?
All Arrhenius acids ionize in water to give H+ ions. While Lewis acids are proton donors.
What did the chemist Arrhenius say mixing aqueous acids and bases produces?
salt and water
Why do many compounds that contain one or more hydrogen atoms are not classified as Arrhenius acids?
Some acids contribute H+ directly to the base so the H+ will not be found in solution.
Describe the major limitation of the Arrhenius theory of acids and bases?
Arrhenius's theory was limited by the fact that hydrochloric acid is neutralised by both sodium hydroxide solution and ammonia solution. In both cases, you get a colourless solution which you can crystallise to get a white salt - either sodium chloride or ammonium chloride.
The traditional definition of acids is based on the observations of?
i believe it is the Arrhenius Concept. (:
What is Arrhenius definition of an acid?
Compounds are acids if they ionize to release H+ ions in aqueous solutions.
What is common to all Arrhenius acids?
All Arrhenius acids produces hydrogen ions H+
What are some common things that acids and bases have together?
The Arrhenius definition of acids and bases explains a number of things. Arrhenius's theory explains why all acids have similar properties to each other (and, conversely, why all bases are similar): because all acids release H+ into solution (and all bases release OH-). The Arrhenius definition also explains Boyle's observation that acids and bases counteract each other. This idea, that a base can make an acid weaker, and vice versa, is called neutralization. hope that helped
How does the Bronsted-Lowry definition of an acid differ from the Arrhenius definition of an acid?
Because some acids contribute H+ directly to the base so the H+ will not be found in the solution.
What are two solutions that have more oh ions than H ions?
An arrhenius acid is, by definition, a solution with a higher concentration of H+ ion than OH-. So any arrhenius acid will fit this definition. Two common acids are Lemon juice and vinegar.
What definition did Arrhenius give for acids?
* Arrhenius: According to this definition developed by the Swedish chemist Svante Arrhenius, an acid is a substance that increases the concentration of hydrogen ions (H+), which are carried as hydronium ions (H3O+) when dissolved in water, while bases are substances that increase the concentration of hydroxide ions (OH-). This definition limits acids and bases to substances that can dissolve in water. Around 1800, many French chemists, including Antoine Lavoisier, incorrectly believed that all acids contained oxygen. Indeed the modern German word for oxygen is Sauerstoff (lit. sour substance), as are the Afrikaans and Dutch words for oxygen suurstof and zuurstofrespectively, with the same meaning. English chemists, including Sir Humphry Davy, at the same time believed all acids contained hydrogen. Arrhenius used this belief to develop this definition of acid. Source: Wikipedia - "Acid"
What is true about Arrhenius acids?
it donates H+ ions
Arrhenius defined acids as compounds that?
Contain hydrogen
What are acids and bases according to Arrhenius?
According to Arrhenius, acids produce a proton in aqueous solution, and bases produce a hydroxide ion in aqueous solution. Hydrochloric acid is an Arrhenius acid because it gives up its proton as it dissolves in water. Sodium hydroxide is an Arrhenius base because it gives up its hydroxide as it dissolves in water.
What are solutions that have more OH- than H ions?
An arrhenius acid is, by definition, a solution with a higher concentration of H+ ion than OH-. So any arrhenius acid will fit this definition. Two common acids are Lemon juice and vinegar.
Is arrhenius acids in nature?
yep dats right fellow pals
