Acids And Bases Flashcards
What are properties of an acid
Taste sour, corrosive to metals and skins, pH less than seven, turns blue litmus paper red, reacts with bases to form water and salt, reacts with carbonates
What is the acid in your stomach and what is its pH
HCl, 3
What are the properties of bases
Taste bitter, feel slippery, pH greater than seven, turns red litmus paper blue, react with acids to form water and salt, dissolves wool
Will a strong or weak acid dissociate 100%
Strong Acids will dissociate 100%, weak acids will dissociate less than 10%
What is the products of the dissociation equation for
NaCl + H2O
-> Na+ + Cl- + H2O
What is the products of the dissociation equation for
HCl + H2O
-> H3O+ + Cl-
Name the six strong acids
HCl HBr HI HClO4 HNO3 H2SO4
What is a strong Base
OH- plus any 1A or 2A metal
What is the Arrhenius definition for an acid
Acids produce a hydrogen ion (H+) in water
What is the Arrhenius definition for a base
Bases produce a hydroxide ion (OH-) in water
What is the Bronsted-Lowry definition for an acid
Acids DONATE a proton (H+), all acids have a conjugate base
Acid is a proton donor
What is the Bronsted-Lowry definition for a base
Bases ACCEPT a proton (H+), all bases have a conjugate acid
Base is a proton acceptor
What is a Amphoteric or Amphoprotic substance
A substance that can act as both an Acid and a Base
What is a neutralization reaction
a double replacement reaction resulting in the formation of salt and water
What is the formula for pH
pH =
- log(H+)
