Answer 1

Answer:

Crystalline

Explanation:

Answer 2

Crystalline substances do not get digested

• Digestion occurs in our body via the action of certain enzymes found in the GIT tract that act on the swallowed substances, and break them down into small digestible units.
• Crystalline substances have a solid, tough, and rigid structure due to the highly ordered microscopic arrangement of the constituting units.
• Enzymes act on specific substrates which do not include these solid crystalline substances and thus, are ineffective in digesting them.

Thus, digestion has no effect when the ppt is (Option 4) Crystalline.
