- If a few drops of a concentrated acid accidentally spill over the hand of a student, wash the hand immediately with plenty of water and apply a paste of sodium hydrogen carbonate.
- Water will dilute the acid and wash it out. Any remaining acid will be neutralized with sodium hydrogen carbonate. This will minimize the effect of acid and damage to the skin.

If a few drops of a concentrated acid accidentally spill over the hand...
Washing the hand immediately with plenty of water and applying a paste of sodium hydrogen carbonate is the correct response when a few drops of a concentrated acid accidentally spill over the hand of a student.
Why is this the correct response?
1. Washing the hand immediately: The first step is to wash the hand immediately with plenty of water to remove the acid from the skin. This helps to dilute and remove the acid, reducing the risk of further damage.
2. Applying a paste of sodium hydrogen carbonate: After washing with water, applying a paste of sodium hydrogen carbonate (also known as baking soda) on the affected area helps to neutralize the acid. Sodium hydrogen carbonate is a weak base that can react with the acid and neutralize its effects. This reduces the chances of further damage to the skin.
3. Why not use saline solution or sodium hydroxide?
- Saline solution: Saline solution is a solution of salt in water, commonly used for rinsing wounds. However, in the case of an acid spill, using only saline solution may not be sufficient to neutralize the acid. It is important to use a substance that can effectively neutralize the acid, such as sodium hydrogen carbonate.
- Sodium hydroxide: Sodium hydroxide is a strong alkali, also known as caustic soda. While it can neutralize acids, it is not recommended to apply it directly on the skin as it can cause further damage. It has the potential to react with the acid and generate heat, which can lead to burns. Therefore, it is safer to use a mild base like sodium hydrogen carbonate.
Summary:
In summary, when a few drops of a concentrated acid accidentally spill over the hand of a student, it is important to wash the hand immediately with plenty of water to remove the acid. After washing, applying a paste of sodium hydrogen carbonate on the affected area helps to neutralize the acid and reduce the risk of further damage. This response is more effective than using saline solution or sodium hydroxide, as it ensures proper neutralization without causing additional harm to the skin.
