Question

Which of the following statements is incorrect?

Question 3 options:

a)

Because organic and inorganic colloids are distinctly different, they do not interact with each other.

b)

Organic colloids usually contain a large number of natural ligands, and therefore have a strong capacity to retain metal ions.

c)

Amino acids have a high capacity as buffers to neutralize H+, or OH-, due to the presence of –NH2

and –COOH groups in their molecular structure.

d)

Inorganic colloids mainly originate from weathering of clays and rock beds. Their surface charge can be altered according to the pH of an environment.

Answer 1

The incorrect option is:

a) Because organic and inorganic colloids are distinctly different, they do not interact with each other.

Explanation: The organic and inorganic colloids are mostly found to interact favorably. There are several reports that discusses the interaction between organic materials with engineered and natural inorganic materials. There are reports that suggest that organic and inorganic materials can be combined together to give new colloids. Hence the statement given in option a is incorrect. The other options are correct here.
