Preparation Of Potassium Sulfite
- Potassium Sulfite is formed by the decomposition of potassium metabisulfite.
K2S2O5 ⇢ K2SO3 + SO2
- Sulfurous acid reacts with potassium hydroxide to form potassium sulfite and water as follows
H2SO3 + 2 KOH ⇢ K2SO3 + 2 H2O
- Potassium sulfite production from potassium sulfate
2 K2SO4 ⇢ 2 K2SO3 + O2
- Redox reaction
2 K + S + 3 O ⇢ K2SO3
- Manganese sulfate reacts with potassium manganate and water to form potassium sulfite manganese dioxide sulfuric acid
4 MnSO4 + 2 KMnO4 + 3 H2O ⇢ K2SO3 + 6 MnO2 + 3 H2SO4
Potassium Sulfite Formula – Structure, Properties, Uses, Sample Questions
Potassium is a chemical element with the symbol K . It is an essential mineral that is needed by all tissues in the body to work properly .it is necessary for the normal functioning of all cells. The largest use of potassium is potassium chloride which is used to make fertilizers. It is important for plant growth. It is the most abundant intracellular cation and an essential nutrient.
Sulfur is a chemical element with the symbol S.it is a nonmetallic chemical element belonging to the oxygen group. It is mostly used in the making of sulfuric acid and used in the vulcanization of black rubber. It is found both in its native form and in metal sulfide ore. Sulfur is used for making car batteries, fertilizer, water processing, and mineral extraction.
Oxygen is a chemical element with the symbol O. It is a gas found in air and has no color, smell, and taste, and is very necessary for life. It is used in industries, water treatment, and as a therapy. If not enough oxygen is circulating in the blood, it gets difficult for the tissues of the heart to keep pumping.
Potassium Sulfite is an inorganic non-flammable white soluble compound with the formula K2SO3. It is the salt of potassium cation and sulfite anion also known as Dipotassium Sulfite, dipotassium salt, and sulfurous acid. It is mainly used in the food industry as a food preservative. To write the formula for this compound the first thing is we need to write the elements of potassium. Potassium is a chemical element with the symbol K available in group I in the periodic table and it has +1 ionic charge K+1 and the sulfate ion SO32-.The chemical formula of potassium sulfite is K2SO3.
