The solubility of Fe(OH) 3 = [Fe 3+ ] = 1.0×10 −18 M

What is pH simple definition?

  • pH is a measure of how acidic/basic water is. The range goes from 0 - 14, with 7 being neutral.
  • pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
  • pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

pOH=14.0−pH=14.0−8.0=6.0

[OH − ]=10 −pOH =10 −6

K sp =[Fe 3+ ][OH − ] 3

1.0×10 −36 =[Fe 3+]×(10 −6) 3

Solubility of Fe(OH) 3 =[Fe 3+ ]=1.0×10 −18 M
