1. What type of adsorption has strong bonding?

Chemical adsorption has strong bonding due to covalent or ionic interactions.

2. What type of phenomenon is absorption?

Absorption is a bulk phenomenon, meaning the substance is taken up throughout the material rather than just on the surface.

3. Is adsorption uniform or non-uniform?

Adsorption is non-uniform, as the amount of adsorbed material varies over the surface.

4. What type of bonding is involved in chemical adsorption?

Chemical adsorption involves covalent and ionic bonding.

5. Is chemical adsorption reversible?

Chemical adsorption is irreversible in most cases.

6. What material is used to make disposable syringes?

Disposable syringes are typically made from polypropylene.

7. What is the purpose of the Water Attack Test?

The Water Attack Test is used to check the alkalinity of glass, specifically for Type II Glass.

8. What is the permitted solid content in Water for Injection (WFI) as per GMP?

The permitted limit is 1.0 ppm for solid content in WFI.

9. What is the sterilization temperature for aqueous solutions in an autoclave?

Aqueous solutions are sterilized at 121°C using moist heat in an autoclave.

10. How long is the sterility test incubation for surgical sutures?

The sterility test requires 14 days of incubation.

11. Which amphoteric surfactant is used in pharmaceutical dispersions?

Lecithin and bile salts are examples of amphoteric surfactants.

12. What is an abrasive used in dentifrices (toothpaste)?

Dicalcium Phosphate is commonly used as an abrasive in dentifrices.

13. What does the Florentine receiver separate liquids based on?

A Florentine receiver separates liquids based on density differences.

14. What is another term for Vander-Waals adsorption?

Vander-Waals adsorption is also known as physical adsorption or physi-adsorption.

15. What factors affect physi-adsorption?

Physi-adsorption is influenced by temperature and pressure.
