No, lead generally does not react with water.
Why Lead Is Inert Towards Water
Lead is considered an inert metal when it comes to interacting with water. According to the provided information from January 9, 2020, "Metals such as lead, copper, silver and gold do not react with water because these metals are inert towards cold and hot water."
This means that under normal conditions, lead metal resists chemical reaction with water molecules (H₂O), whether the water is cold or hot. Its position in the reactivity series places it below elements that readily react with water, like alkali metals (sodium, potassium) or alkaline earth metals (calcium, magnesium).
Practical Implications of Lead's Inertness to Water
Due to its resistance to reacting with water, lead was historically used for water pipes. While its inertness to water reaction was a factor in its past use, the toxicity of lead itself, which can leach into water over time regardless of direct chemical reaction, has led to its discontinuation for potable water systems in most parts of the world.
Comparing Metal Reactivity with Water
Metals vary significantly in their reactivity with water.
- Highly Reactive Metals: React vigorously or even explosively with cold water (e.g., Sodium, Potassium).
- Moderately Reactive Metals: May react with hot water or steam (e.g., Magnesium, Zinc).
- Low Reactivity Metals: Do not react with water under normal conditions (e.g., Lead, Copper, Silver, Gold).
This low reactivity towards water makes lead, along with copper, silver, and gold, suitable for applications where contact with water is common, provided other factors like toxicity (in the case of lead) are addressed.
