MOH =
Metal hydroxide
HA =
Acid
What is an acid-base neutralization reaction
Acid and base react so that the H+ from the acid and the OH- from the base come together to form water.
What are the 2 types of double replacement reactions?
- acid-base neutralization
- precipitation reactions
In water…
formula units =
molecules =
acids =
- dissociate
- do not dissociate
- dissociate
What is a solution that conducts electricity called?
electrolyte
What is a solution that does conduct electricity called?
nonelectrolyte
What happens when a covalent compound dissolves?
hydration, not no dissociation
What type of behavior do convent acids have?
ionic behavior
What are the 2 types of electrolytes?
- strong
- weak
Strong electrolytes: (4)
- high electrical conductivity
- many ions in solution
- all formula units dissociate
- soluble in water
Weak electrolytes: (4)
- low electrical conductivity
- few ions in solution
- only same formula units dissolve
- insoluble in water
What is the unit for conductivity?
Ms; siemens
What are the 6 strong acids?
- HCl
- HBr
- HI
- HNO3
- H2SO4
- HClO4
What are the 8 strong bases?
- LiOH
- NaOH
- KOH
- RbOH
- CsOH
- Ca(OH)2
- Sr(OH)2
- Ba(OH)2
I cation rule: (6)
Any salt containing (Li, Na K, Rb, Cs, or NH4) is soluble (a strong electrolyte)
II anion rule: (3)
an salt that contains (NO3, C2H3O2, ClO4) is soluble (a strong electrolyte.
II B: (5)
All salts are soluble except (CaSO4, SrSO4, BaSO4, Ag2SO4, PbSO4)
III Cover your bases rule:
If a salt contains neither a cation from rule 1 or an anion from rule II, then its insoluble (weak electrolyte)
What is stoichiometry?
chemical ratio (the coefficients of the balanced chem equation)
