Alum Physical Test | Color: White
Physical State: Solid
Appearance: White Crystalline powder or Octahedral crystals
Odor: Odorless |
Sodium hydroxide reaction to Aluminum hydroxide | Adding Sodium Hydroxide
(NaOH) will cause the
compound Al(OH)3
to precipitate. However,
since Na(OH) is a strong
aqueous base and Al(OH)3
is amphoteric, it will redissolve when more
strong base is added.
the COLOR of the
precipitate Al(OH)3 is WHITE |
