acids and bases Flashcards
(10 cards)
definition of acid
An acid is a substance that can give away a hydrogen ion (proton) to another substance
definition of base
A base is a substance that can take in hydrogen ion from acid
properties of acids
taste sour
produces H+
turn litmus paper red
corrosive in nature
properties of bases
taste bitter
produces OH- ions
turn litmus paper blue
caustic in nature
how to identify acid-base reaction
acid + base -> salt + water
how to identify combustion reaction
Fuel + Oxygen -> Carbon dioxide + water
how to identify acid-metal reaction
acid + metal -> salt + hydrogen gas
how to identify precipitation reaction
in general form: AB + CD -> AD + CB
how to identify acid-carbonate reaction
acid + carbonate -> salt + water + carbon dioxide
difference between complete vs incomplete combustion
complete:
-happens when there is plenty of oxygen
-fuel burns fully
-cleaner and safer
incomplete:
-happens when there is not enough oxygen
-fuel doesn’t burn fully
-produces toxic gases like carbon monoxide
-cause pollution
