Acids And Bases 1 Ch. 10 Flashcards
Describe an acid
Sour taste, turn blue litmus paper red, corrosive, pH < 7
Describe a base
Flat taste, turn red litmus paper blue, corrosive, pH > 7
Monobasic
One hydrogen atom
Dibasic
Two hydrogen atoms
Tribasic
Three hydrogen atoms
What is an Alkali
It is a base that dissolves in water
What is an Arrhenius acid
A substance that dissociates in aqueous solution, forming hydrogen ions
What is an Arrhenius base
It is a substance that dissociates in aqueous solution, forming hydroxide ions.
What is a strong acid according to Arrhenius
Fully dissociates in aqueous solution
What is a weak acid according to Arrhenius
Only slightly dissociates in aqueous solution
What is a strong base according to Arrhenius
Fully dissociates in aqueous solution
What is a weak base according to Arrhenius
Only slightly dissociates in aqueous solution
What does Arrhenius’ conclusions explain
Why strong acids only conduct in aqueous solution, why weak acids do not conduct well, Acids need water before they show their acidic properties
Limitations of Arrhenius’ conclusions
Limited to reactions in water, when acid dissolves in water H30+ is formed rather than a hydrogen ion, does not explain why substances can be an acid and a base
What is a Bronsted-Lowry acid
It is a proton donor
