Acids and Bases Flashcards
List some examples of acids
Hydrocloric acid HCl
Sulphuric acid H2SO4
Phosphoric acid H3PO4
Ethnoic acid
what is produced when a metal reacts with an acid
a salt is produced along with hydrogen gas
What is the general word equation for a metal reacting with an acid
metal + acid= salt + hydrogen
What does the speed of a rection depend on?
How high up in the reactivity series it is
What is the Lab test for Hudrogen
A burning wooden splint goes pop if it is put into a test tube of hydrogen.
The flame ignites the hydrogen, which burns explosively to make a loud sound
List examples of Bases
Sodium hydroxide NaOH
Magnesium Hydroxide Mg(OH)2
Calcium Hydroxide Ca(OH)2
What is the Arrhenius definition of an acid
An acid is a substance that dissociates in water to produce H+ ions
What is the Arrhenius definition of a monobasic acid and give an example
A molecule that dissociates in solution to produce one H+ ion
Eg HCl
What is the Arrhenius definition of a dibasic acid and give an example
A molecule that dissociates in solution to produce two H+ ions
Eg H2SO4
What is the Arrhenius definition of a tribasic acid, and give an example
A molecule that dissociates in solution to produce three H+ ions
Eg H3PO4
What does the H+ ion react with water to form
Hydronium ion
What is the general formula for the dissociation of acids in water
H(acid) +H2O = H3O+(Acid)-
What is a Arrhenius Base
A base is a substance that dissociates in water to produce OH- ions
What is a Arrhenius strong acid
A strong acid dissociates almost fully in aqueous solution
What is a Arrhenius string base
Dissociates almost fully in aqueous solution
