| Temperature (°C) | Solubility (g/100 mL) |
|------------------|-----------------------|
| 20 | 4.85 |
| 40 | 8.25 |
| 60 | 12.5 |
| 80 | 17.5 |
| 100 | 25.0 |

## Mode of Action

The disinfectant properties of di-sodium tetraborate decahydrate are primarily due to its ability to disrupt the cell membrane and interfere with the metabolism of microorganisms. When dissolved in water, the compound releases boric acid, which has a low pH. This acidic environment is detrimental to the survival of many microorganisms, including bacteria, viruses, and fungi.

### Disruption of Cell Membrane

The acidic environment created by boric acid disrupts the cell membrane of microorganisms. This disruption leads to the leakage of cellular contents, ultimately resulting in the death of the microorganism. The process is effective against both Gram-positive and Gram-negative bacteria.

### Interference with Metabolism

In addition to disrupting the cell membrane, boric acid also interferes with the metabolism of microorganisms. It inhibits the synthesis of essential cellular components, such as proteins and nucleic acids, leading to the death of the microorganism.

## Applications in Disinfection

Di-sodium tetraborate decahydrate solutions are widely used in various disinfection scenarios, including:

### Water Treatment

Di-sodium tetraborate decahydrate solutions are used in water treatment plants to control the growth of algae and bacteria. The compound is added to the water supply to maintain a low pH, which inhibits the growth of microorganisms.

### Surface Disinfection

The compound is also used for surface disinfection in hospitals, laboratories, and other facilities. It is effective against a wide range of microorganisms, making it a versatile disinfectant for various surfaces.

### Personal Hygiene

Di-sodium tetraborate decahydrate solutions are used in personal hygiene products, such as antiseptic hand washes and mouthwashes. The compound helps to kill bacteria and prevent infections.

## Advantages and Limitations

### Advantages

- **Non-toxic**: Di-sodium tetraborate decahydrate is considered non-toxic to humans and animals, making it a safe option for disinfection.
- **Versatile**: The compound is effective against a wide range of microorganisms, making it a versatile disinfectant.
- **Economical**: Di-sodium tetraborate decahydrate is relatively inexpensive, making it an economical option for disinfection.

### Limitations
