lowing chemical sanitizers. Complete the table below in your notebook.
Sanitizer/Disinfectant
Advantage(s)
Disadvantage(s)
1. Chlorine
2. lodine
3. Alcohol
4. Hydrogen peroxide
5. Formaldehyde​

Answer 1

Answer:

1.Chlorine

Advantages

Chlorine is used to disinfect water and to clean swimming pool. It is regular in pools and helps clean all the germs out in them.

Disadvantages

Chlorine can be a very dangerous poison it can cause throat swelling and water filling in the lungs.

2.Iodine

Advantages

Forms of brown color that indicates strength;not affected by hard water;less irritating to the skin that is chlorine and activity not lost rapidly in the presence of organic matter.

Disadvatages

Effectiveness decrease greatly with an increase in pH/most active at pH 3.0; very low active at pH 7.0); should not be used in water that is at 120oF or hotter;and might discolor equipment and surfaces

3.Alcohol

Advantages

Wide microbical activity,noncrrosive

Disadvantages

Not universally sporicidal limited residual activity fire hazard

4.Hydrogen Perovide

Advantages

Safe from environment,leaves no toxic residual

Disadvantages

Hydrogen peroxiede maybe toxic at levels greater than 1ppmTWA

Answer 2

Advantages and disadvantages of the given chemical sanitizers/ disinfectants are as follows:

Chlorine:

Advantages:

• Causes oxidation of cellular materials and destruction of vegetative bacteria and fungi.
• The death of almost all microbes occurs in under 30 minutes.
• Effective, Inexpensive, and easy to employ.

Disadvantages:

• Chlorine reacts with organic compounds to form carcinogenic chemicals.

Iodine:

Advantages :

• Used as a skin antiseptic, kills microbes by oxidizing cell constituents and iodinating cell proteins.
• At higher concentrations can even kill pathogenic spores.

Disadvantages :

• May cause skin damage
• Leaves a stain on the skin
• Can cause iodine allergies

Alcohol:

Advantages:

• Most commonly used disinfectants, have fungicidal and bactericidal actions.

• Destroys some enveloped viruses
• Act by protein denaturation and dissolution of membrane lipids.

Disadvantages:

• Are not sporicidal, that is they cannot destroy pathogenic spores.

Hydrogen peroxide ($H_{2} O_{2}$):

Advantages:

• Can disinfect inanimate objects.
• Is sporicidal at higher concentrations

Disadvantages:

• Not a good antiseptic for open wounds.
• Easily broken down into water and oxygen by human cellular enzymes.

Formaldehyde:

Advantages:

• Highly reactive molecules that bind with nucleic acids and proteins and inactivate them.
• Are sporicidal in nature and can be used as chemical sterilants.

Disadvantages:

• Can cause irritation.
