What is a Chromic acid (H₂CrO₄)?

Chromic acid (H₂CrO₄) is a strong oxidizing acid that is widely used in various industrial applications. It is typically formed by dissolving chromium trioxide (CrO₃) in water, resulting in a yellow or colorless solution. As a powerful oxidizer, chromic acid is used in metal cleaning, surface treatment, and electroplating, where it improves the corrosion resistance of metals. It also serves as a catalyst in chemical reactions.

However, chromic acid is highly toxic. Exposure can cause respiratory and skin irritation and is associated with long-term health risks such as cancer. Because of its toxicity, the use of chromic acid is strictly regulated to prevent environmental contamination and ensure safe handling.
