Product Description
What Is Hydrochloric Acid?
Hydrochloric Acid (HCl) is a highly corrosive, strong acid used extensively in industries such as metal cleaning, pH control, and chemical production. It usually manifests as a transparent, colorless liquid when dissolved in water.
Hydrochloric acid is commonly produced by absorbing hydrogen chloride gas (HCl) into water. Alternatively, it can be synthesized through the reaction of sodium chloride (NaCl) with sulfuric acid (H₂SO₄) in certain industrial processes.

User Asked Question:
Q: What is the concentration of commercial hydrochloric acid?
A: Commercial hydrochloric acid is typically available in concentrations ranging from 10% to 38%. The concentration depends on the intended use:
Diluted solutions (around 10% to 20%) are commonly used for cleaning and general industrial applications.
Concentrated solutions (around 30% to 38%) are used for more intensive industrial processes, such as chemical production and metal cleaning.
Higher concentrations are available for specific industrial or laboratory applications.
