Sodium carboxymethyl cellulose (CMC) is a versatile compound with a wide range of applications across various industries. Here are some common uses:

1. **Food Industry:**
   - **Thickener and Stabilizer:** CMC is widely used as a thickening agent and stabilizer in the food industry. It can improve the texture, viscosity, and mouthfeel of a wide range of food products, including sauces, dressings, dairy products, and baked goods.
   - **Emulsifier:** CMC can also act as an emulsifier, helping to stabilize oil-in-water emulsions in products like salad dressings and ice cream.
   - **Binder:** In food processing, CMC can serve as a binder to improve the cohesion and texture of meat products, such as sausages and burgers.

2. **Pharmaceuticals:**
   - **Tablet Binder:** CMC is commonly used as a binder in pharmaceutical tablet formulations. It helps hold the ingredients together and ensures uniformity in the tablet's structure.

Magnesium sulphate heptahydrate, commonly known as Epsom salt, plays a crucial role in agriculture due to its rich source of magnesium and sulfur, both essential nutrients for plant growth and development. Here are some key ways in which magnesium sulphate heptahydrate is used in agriculture:

1. **Soil Amendment:** Magnesium is a vital component of chlorophyll, the pigment responsible for photosynthesis in plants. By incorporating magnesium sulphate into the soil, farmers can correct magnesium deficiencies, ensuring healthy chlorophyll levels and optimal photosynthetic activity. This leads to improved plant vigor, enhanced growth, and increased yield.

2. **Nutrient Uptake:** Sulfur is another essential nutrient required by plants for various metabolic processes, including protein synthesis and enzyme activation. Magnesium sulphate provides a readily available source of sulfur, promoting efficient nutrient uptake and utilization by plants. This leads to improved nutrient
