acids
- PHYSICAL properties
- sour
taste
- dissolve in h20 to
form or produce
solutions that
conducts electricity
- turn MOIST blue
litmus red
- turns universal indicator
- orange (weak
acid)
- red(strong acid)
- chemical
properties
- acid+ reactive metal= metal salt + hydrogen gas
- (unreactive metal) :
silver/gold /copper
- hcl + zinc= zinc chloride + hydrogen gas
- (test for hydrogen
gas:) place lighted
spilt at the mouth
of the test tube.
the lighted spilnt will
extinguished with a
pop sound
- acid+ carbonate= salt + carbon dioxide + water
- hno3 + zinc carbonate= zinc nitrate +h20 +co2
- test for carbon dioxide :
bulblble gas with limewater , a
white percipitate will be
formed
- acid+base= salt + water
- base is any metal oxide or hydroxide
- h2so4 + calcium hydroxide =
calcium sulfate + h20
- acid +alkali = salt + water
- neutralisation
- sodium hydroxide+ hno3 = sodium nitrate + h20
- hydrocloric acid (hcl),
nitric acid(hno3),
sulfuric acid(h2so4)
- WHAT? : produce h+ ions in aq solutions
when dissolve in water
