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

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 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 the three Acid Base Theories?
Arrhenius, Bronsted-Lowry, and Lewis theories of acids and bases
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.

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

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.....
Why was the Arrhenius theory of acids and bases modified?
It had so many limitations which was found out by the later scientists; Bronsted and Lowry, who came up with their theories afterwards
Is it right all Arrhenius bases are Brownsted Lowry bases?
Yes, because all Arrhenius bases contain OH- ions which accept the proton.
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"
How do you know if a molecule is a base or an acid?
In brief: It could be done by measuring its pH level. Descriptive: There are a few ways to define an acid or a base: Arrhenius Defined acids and bases this way: Arrhenius Acids form H+ in solution Arrhenius Bases form OH- in solution Bronsted and Lowry defined acids and bases this way: Bronsted-Lowry Acids donate an H+ in solution Bronsted-Lowry Bases accept an H+ in solution OR in more general terms: Lewis defined acids and bases this way: Lewis Acids are defined as: Electron pair acceptors Lewis Bases are defined as: Electron pair donors As the user above me has already stated, you can also measure its pH. pH measures the concentration of Hydronium ions in a solution (H3O+) (it is NOT H+; H+ does not really exist by itself in this form). pH measurements range from 0 to 14 at the temperature of 298 K (25 centigrade). IF: pH < 7, it is acidic. pH = 7, it is neutral; neither acidic nor basic pH > 7, it is basic.
What is Arrhenius acid base concept?
Acids are substances that will donate a proton, while bases are substances that will accept a proton.
