Acid Safety: Adding Water to Concentrated Acid

When concentrated acid is mixed with water, a significant amount of heat is released. This process is known as an exothermic reaction.

Understanding the Risk

• Adding water to concentrated acid causes the water, which is less dense, to sit on the surface.
• The intense heat generated quickly boils the water.
• This rapid boiling causes the mixture to violently splash upwards.

Consequences of Splashing

The splashed liquid is hot, concentrated acid, which is highly corrosive. Direct contact can cause severe skin burns and eye damage.

Correct Procedure

For safety, always add concentrated acid slowly to a larger volume of water, while stirring continuously. This allows the heat to dissipate more safely.

Conclusion

Therefore, adding water quickly to a concentrated acid is dangerous because the solution is likely to splash, potentially causing serious harm.
