| 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 |
| Alum crystal Flame Test | Produces lilac color |
| Baking soda uses | 1 Reduces acidity in the stomach
2 Removes dirt off materials
3 Pesticide
4 Eardrops, cosmetics, Personal care products |
