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)
