TCCA 90 Chlorine Granules refer to a type of chlorine compound commonly used for disinfecting swimming pools, hot tubs, and other water treatment systems. TCCA stands for Trichloroisocyanuric acid, and the "90" indicates that the product contains 90% available chlorine. These granules are highly effective in sanitizing and controlling bacteria, algae, and other microorganisms in pool water.

Here are some key points about TCCA 90 Chlorine Granules:

1. High Chlorine Content: As a concentrated form of chlorine, TCCA 90 provides a potent and long-lasting disinfectant.
2. Quick Dissolution: These granules dissolve rapidly in water, making them easy to use.
3. Effective Algaecide: TCCA 90 helps prevent the growth of algae, keeping pools clean and clear.
4. Convenient Packaging: Typically, TCCA 90 is available in granular form, which allows for easy measurement and application.
5. Stabilized Chlorine: The product is stabilized with cyanuric acid, which reduces the chlorine degradation caused by sunlight, extending the effectiveness of the chlorine.

When using TCCA 90, it’s important to follow the recommended dosage instructions carefully to avoid over-chlorination, which can lead to skin irritation, eye discomfort, or other negative effects on water quality.

Bleaching powder, commonly known as calcium hypochlorite, is an inorganic compound with the chemical formula Ca(OCl)₂.

Chemical Properties:

• Chemical Formula: Ca(OCl)₂
• Molar Mass: 142.98 g/mol
• Density: Approximately 2.35 g/cm³ at 20 °C
• Melting Point: Decomposes at around 175 °C
• Solubility: Soluble in water, releasing chlorine gas upon contact

Production:

Calcium hypochlorite is produced by reacting moist slaked lime (calcium hydroxide) with chlorine gas. The reaction yields bleaching powder and water:

Ca(OH)2+2Cl2→Ca(OCl)2+2H2O\text{Ca(OH)}_2 + 2 \text{Cl}_2 \rightarrow \text{Ca(OCl)}_2 + 2 \text{H}_2\text{O} Ca(OH)2​+2Cl2​→Ca(OCl)2​+2H2​O

Uses:

• Bleaching Agent: Historically used in the bleaching of textiles and paper products.
• Disinfectant: Effective in sanitizing drinking water, swimming pools, and surfaces due to its strong oxidizing properties.
• Organic Synthesis: Utilized as an oxidizing agent in various chemical reactions, including the haloform reaction to produce chloroform.

Safety Considerations:

Bleaching powder is a strong oxidizing agent and should be handled with care. It should be stored away from acids, organic materials, and metals to prevent hazardous reactions. Proper ventilation is essential when using it in confined spaces.

In summary, bleaching powder (calcium hypochlorite) is a versatile compound with applications in disinfection and organic synthesis. However, its reactive nature necessitates careful handling and storage.
