What is Drano?

Drano is a brand of drain cleaner that is commonly found in homes and offices. It is a chemical-based product that is designed to dissolve clogs in pipes and drains. Drano is a combination of several chemicals, including sodium hydroxide, sodium nitrate, and aluminum. The chemical formula for Drano is NaOH + NaNO3 + Al.

How Does Drano Work?

Drano works by creating a chemical reaction that dissolves clogs in pipes and drains. When Drano comes into contact with water, it reacts with the aluminum in the formula to produce heat and hydrogen gas. The heat helps to break down the clog, while the hydrogen gas helps to dislodge it. The sodium hydroxide in Drano is a strong base that can dissolve organic matter, such as hair and grease.

While Drano is an effective drain cleaner, it can be dangerous if not used properly. The chemicals in Drano can cause chemical burns and irritation to the skin and eyes. It is important to wear protective gloves and eyewear when using Drano. In addition, Drano should never be mixed with other chemicals, as this can cause a dangerous chemical reaction.
