While diluting an acid, why is it recommended that acid should be added to water and not water to acid?

When diluting an acid, it's crucial to add acid to water rather than the other way around. This practice is important for safety and chemical stability.

Reasons for the Recommended Method

• Exothermic Reaction: Mixing acid with water can release a significant amount of heat. If water is added to concentrated acid, the heat generated can cause the mixture to boil and splatter, potentially leading to burns or injuries.
• Controlled Dilution: Adding acid to water allows for better control over the dilution process. The water can absorb the heat more effectively, reducing the risk of violent reactions.
• Minimizing Splashing: When acid is poured into water, it disperses evenly, minimizing the chance of splashing. Conversely, adding water to acid can cause the acid to surge and splash out of the container.

Safety First

Always prioritize safety when handling chemicals. Wearing protective gear, such as gloves and goggles, is essential to prevent accidents.

Summary

In summary, adding acid to water is a safer method that helps prevent dangerous reactions and ensures a more controlled dilution process.
