Question

S>SO2>H2SO3>Na2SO3>Ag2SO3

Answer 1

S+O2=SO2
SO2+H2O=H2SO3
H2SO3+2NaOH=Na2SO3+2H2O
Na2SO3+2AgNO3=Ag2SO3+2NaNO3

Answer 2

The given expression "S > SO2 > H2SO3 > Na2SO3 > Ag2SO3" represents a series of chemical compounds in a specific order. Let's break down each compound and discuss their properties.

Sulfur (S)

Sulfur (S) is a chemical element with the atomic number 16. It is a yellow, brittle solid that occurs naturally in the Earth's crust. Sulfur is commonly used in the production of sulfuric acid and various other chemical compounds. It is also an essential element in many biological processes.

Sulfur Dioxide (SO2)

Sulfur dioxide (SO2) is a colorless gas with a pungent odor. It is produced by burning sulfur-containing fuels, such as coal and oil, and is a major air pollutant. SO2 is also released during volcanic eruptions. It is used in various industrial processes, including the production of sulfuric acid, bleaching agents, and preservatives.

Sulfurous Acid (H2SO3)

Sulfurous acid (H2SO3) is a weak acid that forms when sulfur dioxide dissolves in water. It is a relatively unstable compound and exists mainly in solution. Sulfurous acid is used as a reducing agent and in the production of various chemicals.

Sodium Sulfite (Na2SO3)

Sodium sulfite (Na2SO3) is a white, crystalline compound. It is formed by reacting sodium hydroxide with sulfur dioxide. Sodium sulfite is commonly used as a preservative in the food and beverage industry, as well as in the production of paper and textiles.

Silver Sulfite (Ag2SO3)

Silver sulfite (Ag2SO3) is a silver salt of sulfurous acid. It is a white, crystalline solid that is sparingly soluble in water. Silver sulfite is primarily used in analytical chemistry and as a reagent in various chemical reactions.

In the given expression, the ">" symbol represents a greater-than relationship, indicating that each compound is considered to be "greater" or more significant than the one that follows it. It is important to note that this expression does not provide any specific context or criteria for comparison. Therefore, it is difficult to determine the exact basis for the comparison between these compounds.
