Quoted from Merdeka.com, sulfuric acid (H2SO4) is a type of strong mineral (inorganic) acid. Sulfuric acid has many uses and is one of the main products of the chemical industry. Sulfuric acid is usually used in mineral ore processing, chemical synthesis, wastewater treatment, and oil refining. Not only that, sulfuric acid is also contained in battery water which functions as a conductor and electricity storage.

The translation of the given text from Bahasa to English while preserving any HTML tags is as follows: The process of making sulfuric acid in the industry is known as the contact process, which is a process where sulfuric acid is made directly from sulfur burned in the air to produce sulfur dioxide. Then, with the help of a catalyst (vanadium pentoxide), sulfur dioxide is oxidized into sulfur trioxide compound. Finally, sulfuric acid is formed by reacting sulfur trioxide with water.

Folic acid can also protect against nerve damage and hydrocephalus caused by fluid trapped in the baby's brain, causing the baby's head to swell and appear frightening. Research shows that pregnant women need a large amount of folic acid in their blood to ensure normal development of the baby's nerves and brain. It would be very beneficial if pregnant mothers have consumed enough folic acid three months prior to their pregnancy.
