It had so many limitations which was found out by the later scientists; Bronsted and Lowry, who came up with their theories afterwards

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


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.


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.


What did the chemist Arrhenius say mixing aqueous acids and bases produces?

salt and water


What are the three Acid Base Theories?

Arrhenius, Bronsted-Lowry, and Lewis theories of acids and bases


How do you tell acids and bases apart according to Arrhenius?

Acids were compounds with hydrogen that ionized when aqueous to form H+. Bases were compounds that ionized when aqueous to form OH- (hydroxide).


What theory of acids and bases do conjugate acids and bases belong to?

Bronsted-Lowry


Why the Arrhenius model of acids and bases does not include ammonia in solution as base?

because arrhenius model does not include some elementa as they dont contain hydroxide before the reaction


Are Arrhenius bases an electrolyte?

All acids and bases are electrolytes. Some are more powerful than others, depending on the extent of ionization and dissociation of the solution.


How did each scientist define an acid and a base?

There are several commonly-used definitions for acids and bases. Prior to the 20th century, acids were largely viewed as substances containing oxygen and hydrogen which would react with metals. Around the turn of the 20th century, Svante Arrhenius defined an acid as a substance which could dissociate to generate positively-charged hydrogen ions ([H+], later recognized to exist as hydronium ions, [H3O+]) in solution, while a base would dissociate to form negatively-charged hydroxide ions ([OH-]). Johannes Brønsted and Martin Lowry later expanded this definition, with an acid as a proton donor and a base as a proton acceptor. This meant that a substance could be an acid without forming hydronium ions in solution. Around the same time, Gilbert Lewis developed a theory suggesting that an acid is a substance which could accept an electron pair and a that a base is a substance which can donate an electron pair.


Why statement describes an alternate theory of acids and bases?

Acids are H+ donors, and bases are H+ acceptors.


Limitations of the Arrhenius definitions of acids and bases?

the Arrhenius definitions stated that acids would donate a Hydrogen (H+)in water and a base would donate a hydroxide(OH-) in water, but would limit to substances with those "parts" like ammonia for example because it could do both.....
