Is drinking a small percentage of sodium hydroxide safe?

Sodium hydroxide (NaOH), also known as lye or caustic soda, is a highly corrosive alkali that can cause severe burns and tissue damage if ingested. Even small amounts can be dangerous and can lead to serious health problems, including esophageal perforation, internal bleeding, and even death.

The level of toxicity of sodium hydroxide depends on the concentration of the solution and the amount ingested. Generally speaking, the higher the concentration and the larger the amount ingested, the more severe the health effects will be.

Even small amounts of sodium hydroxide can cause irritation and damage to the mouth, throat, and esophagus. In some cases, it can also lead to nausea, vomiting, and abdominal pain. In more severe cases, it can cause difficulty breathing, low blood pressure, and seizures.

It is important to seek medical attention immediately if you have ingested any amount of sodium hydroxide. The sooner you receive treatment, the better the chances of minimizing the health effects.
