Thymoil Blue 25gm
Thymol blue is a chemical compound that is used as a pH indicator. It typically appears as a greenish-yellow powder and is commonly used in laboratories and in various applications where pH monitoring is necessary, such as in swimming pools and aquariums. In solutions with a pH below 1.2, thymol blue appears yellow, and in solutions with a pH above 2.8, it appears blue. Its color change range makes it useful for indicating acidic to neutral pH levels.
Zinc Chloride 500gm
Zinc chloride (ZnCl₂) is a white crystalline solid that is highly soluble in water. It is hygroscopic, meaning it can absorb moisture from the air. Zinc chloride is commonly used in various industrial applications, such as a flux for soldering, a catalyst in organic synthesis, and a wood preservative. It also has uses in textile processing, chemical synthesis, and as a disinfectant. Due to its ability to dissolve in water and its caustic nature, it should be handled with care, using appropriate safety measures.
