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
- acid+ reactive metal= metal salt + hydrogen gas
hydrocloric acid (hcl), nitric acid(hno3), sulfuric acid(h2so4)
WHAT? : produce h+ ions in aq solutions when dissolve in water
