Question

5.- Explain why a colloidal dispersion will sediment at different rates if instead of adding a Ba Ch Aluminum hydroxide is added. Which one will sediment faster? The colloidal dispersion will sediment faster with Ba Cl2--or Al(OH) Select the proper explanation: a.- adding a salt with a cation with the higher oxidation number will increase the sedimentation rate because it will increase the Z potential b.- adding a salt with a cation with the higher oxidation number will increase the sedimentation rate because it will decrease the Z potential c.-.- adding a salt with an anion with the higher oxidation number will increase the sedimentation rate because it will increase the Z potential d.- c.- - adding a salt with an anion with the higher oxidation number will increase the sedimentation rate because it will decrease the Z potential

Explanation / Answer

The colloidal sediment will be at faster rate with Al(OH)3 than that with BaCl2 because a. adding a salt with a cataion with higher oxidation number will increase the sedimentation rate because it will increase zeta potential.
