Dilutions
Electrolyte
- Conducts electricity
- ionic compounds in
conduct electricity
- more ions = better conductivity
Combustion Reactions
Unknown compound (s) reacts with
and
produces
Precipitation Reactions
Formation of insoluble salts from mixing 2
dissolved ionic compounds.
Depending whether the ionic compound is either
soluble or insoluble:
If the ionic compound is soluble, then no
precipitate.
If the ionic compound is insoluble, then a
precipitate is formed.
Acids
- formula either begin with H (except
) or contain -COOH ( carboxylic acid)
- defines as proton donors:
- Strong acids - dissociates completely in
[Note: only strong acids breaks up in net ionic eqn]
- weak acids: carboxylic acids
6 strong acids (Must Remember!):
hydrochloric acid
hydrobromic acid
hydriodic acid
nitric acid
sulfric acid
perchloric acid
Base
- produce
in water
- proton acceptor
- Strong bases - Group I and II metals with hydroxide (
- Weak bases - amines
and carbonates
)
Neutralization Reaction
- acid and base combine to make
and an ionic compound (usually soluble)
- * only dissolved ionic compounds can be written as separate ions.
Acids with carbonates
- acid and carbonates reacts and produce
and
Net Ionic Equation:
an ionic compound (usually soluble)
