Re: alkalizing water.

 HV stated that "Alkaline water contain caustic hydroxides (OH)"

A hydroxide is OH-, not *OH*... *OH* is a hydroxyl... an electron makes the difference and is noted by the minus sign in OH- for the hydroxide. So the statement is incorrect. And these two molecules have very different chemical properties.

OH- can join with a *free radical* neutralizing it, while the OH IS a free radical.

I know it gets confusing to some... including apparently HV based upon the incorrect statement above.

First of all my statements WERE NOT incorrect.  The whole concept of Kangan alkaline water is to make hydroxides such as calcium hydroxide, magnesium hydroxide, etc.  This is from the electrolysis of mineralized waters.  The reason they want you to use mineralized water to make the alkaline water is so you can form mineral hydroxides.  As the water (HOH) is subjected to electrolysis the H and the OH are split.  The H helps form the acidic water while the OH binds with the minerals in the water forming the mineral hydroxides.

Hydroxides are very well known for their caustic nature damaging tissues.  Great examples are sodium hydroxide (lye) also known as "CAUSTIC soda", potassium hydroxide (lye, also what Drano is made from) also known as "CAUSTIC potash", calcium hydroxide (lime) also known as "CAUSTIC lime", magnesium hydroxide (used as a laxative because it burns the intestinal wall), etc.  There is a very good reason that these compounds have warning labels not to contact tissues.  Again it is because they are caustic, some highly so.

They are also well known for creating free radicals:

Does CaOH2 Kill Bacteria ?

 

YES

1. Siqueira – pH (12.5) alters enzyme activity disrupting cellular metabolism
   • Hydroxyl ions create free radicals – destroy cell membranes
   • Free radicals react with bacterial DNA, inhibition
     

 

 

What Grz was referring to when he stated OH- was the hydroxyl ion, which as shown above CREATES free radicals.  That is the opposite of his claim that they join free radicals neutralizing them.

To get nitpicky over whether I wrote "OH" or "OH-" is really rather ridiculous.  Note I said HYDROXIDES not hydroxide, thus noting more than one.  What are those hydroxides?  Well, let's see there is calcium HYDROXIDE (Ca(OH)₂), magnesium HYDROXIDE (Mg(OH)₂), potassium HYDROXIDE (KOH), etc.  Note they are not written chemically as "Ca(OH)₂-", "Mg(OH)₂-", "KOH-", etc.  And to show what I am referring to here is the definition of "hydroxide":

http://encyclopedia.farlex.com/hydroxide

"hydroxide

 

Any inorganic chemical compound containing one or more hydroxyl (OH) groups and generally combined with a metal. Hydroxides include sodium hydroxide (caustic soda, NaOH), potassium hydroxide (caustic potash, KOH), and calcium hydroxide (slaked lime, Ca(OH)₂)."

 

And:

http://www.infoplease.com/ce6/sci/A0824737.html

 

hydroxide

hydroxide (hīdrok'sīd) [key], chemical compound that contains the hydroxyl (-OH) radical.

 

 

As we can see the term "hydroxide" goes well beyond the simple claim that hydroxide is only OH-.

To go further with this, if Grz wants to be so nitpicky why did he not point out that "OH" can actually refer to the hydroxyl RADICAL  as well.  

Since he brought up calcium hydroxide I also want to point out that calcium hydroxide disassociates in water forming OH-:

Ca(OH)2(s) <==> Ca++ + 2OH-

which as pointed out earlier leads to free radical formation.
