* pH Scale: The pH scale measures acidity and alkalinity. A pH of 7 is neutral, while values below 7 are acidic and values above 7 are alkaline (also called basic).
* Strong Alkali: A pH of 12 indicates a very strong alkali.
* Skin Damage: Strong alkalis can cause severe skin damage, including:
* Burns: Chemical burns can be very painful and lead to scarring.
* Irritation: Redness, itching, and inflammation.
* Dehydration: Alkalis can strip away natural oils and moisture from the skin.
* Long-Term Damage: Repeated exposure can lead to chronic skin conditions.
Safety Precautions:
* Avoid Contact: Never touch a pH 12 solution with bare skin.
* Wear Protective Gear: Use gloves, goggles, and appropriate clothing when handling such solutions.
* Immediate First Aid: If skin contact occurs, immediately flush the affected area with plenty of water for at least 15 minutes. Seek medical attention.
