Acids and Bases Flashcards
Why do acids ionize?
To form hydrogen ion and anion so that hydrogen can bond with H2O to create H3O
Hydronium ions (H3O) are responsible for?
Acidic properties
Hydroxide ions (OH) are responsible for?
Basic properties
Original and Modified Arrhenius theory for acid
O: substance that produces H+ in solution
M: substance that react w/ water to produce H3O
Original and Modified Arrhenius Theory for base
O: Substance that produces OH in solution
M : Substance that react w/ water to produce OH
Acid Properties
- Sour
- Turn blue litmus to red
- Ph less than 7
- pOH greater than 7
- Neutralize bases
- react w/ active metals to produce hydrogen gas
- react w/ carbonates to produce CO2
Polyprotic Acids
Contain more than one acidic hydrogen in their compound formula and react more than once w/ water
Base Properties
- Bitter and feel slippery
- Turn red litmus blue
- pH grater than 7
- pOH less than 7
- Neutralize acids
- Dissociate into hydroxide ions and cations

Hydronium ions
- Greater the concentration of hydronium ions, the more acidic the solution
Concentration of H3O+ indications
- Neutral Solutions: [H3O+] = 1.0 x 10^-7 mol/L
- Acidic Solutions: [H3O+] > 1.0 x 10^-7 mol/L
- Basic Solutions: [H3O+] < 1.0 x 10^-7 mol/L
Calculating pH and [H30+]
- [H30+] = 10^-pH
- pH = -log[H30+]
Calculating pOH and [OH-]
- [OH-] = 10^-pOH
- pOH = -log[OH-]
