Sulfur’s Chemical Properties and Trends in the Periodic Table

One of the most distinguishing features of sulfur chemistry is its ability to bond with itself and form long chains or networks. This property applies not only to elemental sulfur (S8), but also to other sulfur molecules that contain double-bonded or triple-bonded atoms. Due to the presence of these multiple bonds between sulfur atoms, sulfur-containing compounds generally have high melting points and are often insoluble in water.

Sulfur is known to exhibit allotropy; it exists in several different forms. Some of the common allotropes of sulfur include:

  • Elemental sulfur (non-reactive yellow crystalline solid)
  • Monoatomic sulfur (colorless gas)
  • Sulfur ions (S2-, S22-, and S42-)

As with all elements, sulfur follows specific trends when placed in the periodic table. One such trend is its tendency to form increasingly acidic oxides as one moves from left to right across a period. For example, sulfur dioxide (SO2) has moderate acidity but sulfur trioxide (SO3) possesses high acidity due to its extensive hydrogen bonding.

In terms of reactivity, sulfur’s behavior is context-dependent. It can be both a reducing agent or an oxidizing agent depending on what it reacts with. For instance, sulfur reduces copper oxide to form copper sulfide (CuS), but oxidizes iron to form iron(II) sulfate (FeSO4).

How to Balance Chemical Equations with Sulfur (S)

Identifying Sulfur-Containing Compounds in Equations

Sulfur is a chemical element that commonly appears in many compounds. It is represented by the symbol “S” in the periodic table of elements. When balancing chemical equations, it is essential to identify sulfur-containing compounds and their coefficients in order to ensure the equation is accurately balanced.

The most common sulfur-containing compounds include sulfates (SO4-2), sulfides (S-2), and hydrogen sulfide (H2S). These compounds can be identified in the chemical equation by looking at the formula displayed for each compound. For example, any compound that contains SO4-2, such as magnesium sulfate (MgSO4), will have sulfur present and must be accounted for when balancing the equation.

Using Coefficients to Balance Equations Involving Sulfur

In order to balance an equation that involves sulfur, one must first determine how much sulfur is present in the reactants and products. This can be done by counting the number of sulfur atoms on both sides of the equation. For example, if we consider the following unbalanced equation:

“FeS + HNO3 → Fe(NO3)2 + NO + H2O + SO2

We can observe that there are 1 sulfur atom on the left side and 3 sulfur atoms on the right side of the equation. This means that we need to add a coefficient to the sulfur dioxide (SO2) on the right side of the equation in order to attain balance. By adding a coefficient of 3 to SO2, we can balance the sulfur-containing compounds in this chemical equation:

“FeS + HNO3 → Fe(NO3)2 + NO + H2O + 3SO2

It is important to note that while balancing equations with Sulfur or any other element, we must ensure that all atoms present in reactants are also present in products of reaction, ultimately leading to conservation of mass.

Identifying and accounting for sulfur-containing compounds and their coefficients is an essential step in balancing chemical equations accurately. By paying attention to these details, one can balance even complex equations involving sulfates, hydrogen sulfides and sulfides.
