Chemical Formula of Potassium Sulphate
Potassium sulphate is an important inorganic salt used in various applications, particularly in fertilizers. Its chemical formula is K2SO4.
Components of Potassium Sulphate
- Potassium (K):
- Potassium is an alkali metal with an atomic number of 19.
- It is essential for plant growth and is a key nutrient in fertilizers.
- Sulfate (SO4):
- The sulfate ion consists of one sulfur atom (S) and four oxygen atoms (O).
- It carries a charge of -2.
Understanding the Formula K2SO4
- Two Potassium Ions (K+):
- Each potassium ion has a +1 charge.
- Therefore, two potassium ions contribute a total charge of +2.
- One Sulfate Ion (SO4^2-):
- The sulfate ion has a -2 charge.
- This balance of charges (2+ from K and 2- from SO4) maintains electrical neutrality in the compound.
Applications of Potassium Sulphate
- Fertilizers:
- Widely used in agriculture to provide potassium and sulfur, essential nutrients for crops.
- Industrial Uses:
- Employed in the manufacture of glass, ceramics, and as a food additive.
- Chemical Reactions:
- Used in various chemical processes and as a drying agent.
In summary, potassium sulphate (K2SO4) is a vital compound containing potassium and sulfate ions, playing a crucial role in agriculture and industry.
