As you may or may not know water consists of molecules whose molecular formula is H2O. H20 disassociates somewhat into H+ and OH- according to it's equilibrium constant. This disassociation is why water can act somewhat as a buffer. If acid is added to water, the increased H+ concentration causes H+ to bind with OH- to yield H20 and thereby reduce the acidity of the mixture. (I think) laugh

I'm going to get Anny on here later to talk about enzymes. laugh

is Anny back? She's a physicist right?

-never mind - see what happens when you flirt with too many women - you start to get them confused

I always thought water was ionically neutral, for the most part. After all... it's made of hydrogen and oxygen, which are both volatile (as well as flammable) elements.

When the sun is shining when it rains, it is actually raining hydrogen peroxide H2O2, because sunlight charges H2O with and extra Oxygen molecule. happy

You flunked chemistry. Adding water to acid is a no-no from a safety perspective. AAA Always add acid. Secondly, all adding water to acid does is dillute it, raising the PH closer to neutral pH, but not actually neutralizing any acid molecules. There will be some minor variances in dillution, depending on the pollutants in the water that is "added" to the acid solution.

Acid can however be used to harden aluminum in a process called anodizing and depending on the process, can actually make the surface stronger than hardened steel. Simply put, with little more than a car battery and Sulfuric acid, applying an electical current through the metal and dipping it in Sulfuric acid (H2SO4) will induce a replacement reaction, bonding the sulfate from the acid to the aluminum, thus creating a shell of Aluminum Sulfate. If the liquid is near freezing, the surface will be hardened to something close to a Rockwell C65, but will not have the porous structure to absorb a dye.

I have never heard that before, but you reminded me of something similar. If acid rain is so bad, how come we drink it all the time? H2Co3 is in just about every can of soda, and unlike water, is very unstable.

add some bicarb...makes solutions less acidotic...

if u r playing with acids do u keep bicarb or SOMETHING in ur workshop???

Soda ash is a really good idea, and if you can help it, stay away from HF (Hydroflouric acid). You don't know it if you have it on you, because it goes right through the skin and eats at the calcium in your bones. The other acids cause skin burns but are not nearly as dangerous as HF. Another handy thing to have when working with any chemical is the MSDS data sheet on it.

Now imagine being in a farm town of 13,000 and some random individual says, "So, what do you do for a living?" I keep it simple and say, "I invent stuff". If they ask more questions, I'll answer them, but by that time their eyes gloss over and then after the blank stare fades the usual response is, "Oh, okay". You get used to it after a while. laugh laugh laugh laugh laugh
