Question

Carbonic acid occurs in carbonated beverages. When allowed to react with lithium hydroxide, it produces lithium carbonate. Lithium carbonate is used to treat depression and bipolar disorder. Write chemical formulas for carbonic acid, lithium hydroxide, and lithium carbonate.

Short answer

\( H_2CO_3 \), \( LiOH \), \( Li_2CO_3 \).

Step-by-step solution

Determine the Chemical Formula for Carbonic Acid

Carbonic acid is a weak acid that is commonly found in carbonated beverages. The chemical formula for carbonic acid is denoted as \( H_2CO_3 \).

Determine the Chemical Formula for Lithium Hydroxide

Lithium hydroxide, used to neutralize acids and in the production of lithium carbonate, has the chemical formula \( LiOH \).

Determine the Chemical Formula for Lithium Carbonate

Lithium carbonate is a compound formed from the reaction of lithium hydroxide with carbonic acid. The chemical formula for lithium carbonate is \( Li_2CO_3 \).

Key concepts

Carbonic Acid

Carbonic acid is a fascinating compound that plays a crucial role in everyday life, often found in carbonated drinks like soda. Its chemical formula \( H_2CO_3 \) indicates it is made up of two hydrogen atoms, one carbon atom, and three oxygen atoms. This weak acid forms when carbon dioxide dissolves in water and is responsible for the fizzing sensation in beverages.

• It's important in maintaining the pH balance in natural water bodies.
• Acts as a buffer in our blood to stabilize pH.
• Evaporates quickly, making it easily lost to the atmosphere as carbon dioxide.

When carbonic acid is neutralized by a base such as lithium hydroxide, it leads to the production of lithium carbonate, used in various industrial and medical applications.

Lithium Hydroxide

Lithium hydroxide is a strong base represented by the chemical formula \( LiOH \). It is commonly used to neutralize acids, and in certain industrial processes such as the production of ceramics and glass. It reacts readily with carbonic acid to produce lithium carbonate.

• It helps in the production of lithium-ion batteries by purifying lithium hydroxide.
• Finds use in air purification systems to absorb carbon dioxide.
• One of its forms is used as a lubricant in high-temperature applications.

Among its many applications, the reaction with carbonic acid to form lithium carbonate is particularly important due to lithium carbonate's medical uses.

Lithium Carbonate

Lithium carbonate, with the chemical formula \( Li_2CO_3 \), emerges as an essential product of the neutralization of carbonic acid by lithium hydroxide. This compound not only finds utility in various industries but also plays a significant role in healthcare.

• Primarily used in the treatment of mood disorders like depression and bipolar disorder.
• Serves as a precursor in creating other lithium-based compounds, notably in battery technology.
• Utilized in the ceramics and glass industries for its ability to lower melting points during firing.

The chemical reactivity and versatility of lithium carbonate make it a cornerstone compound in both medicinal and industrial fields. Its production through the reaction with carbonic acid highlights an excellent example of chemistry's role in health and industry.
