Hence why you ALWAYS pour the acid into the water, not the other way around! (Ka-BOOOM!!!!)Originally Posted by JimK
The demo I saw of a drop of water dropped into a beaker of HCL resulted in a very violent explosion.

Don't know. I wouldn't recommend trying it. Look it up on YouTube instead.

The heat (enthalpy) of dilution for some acids is given in this link. 31.45% HCl is around 10 so the heat of dilution is roughly 10 kJ/mol. 38.5% Sulfuric acid, by comparison, has a heat of dilution of around 28 kJ/mol so substantially higher. This link calculates the temperature rise for a specific example of adding acid to water and explains why adding water to acid is not a good idea. It basically has the water heat up so much that it can boil and splatter, causing acid to be propelled with it risking getting splashed with concentrated acid.

Re: Water to Acid vs Acid to Water
I like adding the acid slowly to the pool all the way round and letting it fume, I grab my air guitar and sing "Smoke on the water"
