what is the effect of hydrogen peroxide on Silica?

I suspect nothing. worst case maybe corrosion.

During electrolysis, the oxygen atom in H20 has 2 pairs of unbonded electrons, and it is these electrons that act as "solvents" breaking the bond between atoms and attacking the postive ion that forms as a result.  So you can visualize a solution as islands of ions surrounded by water ions, with the extra electrons of oxygen surrounding the positive ions and the negative ions surrounded by the hydrogens of water.  \n\nA "strong" electrolyte is one that dissociates almost completely into ions i.e the water molecules break its bond and surround its ions easily.  HCl is a good example.  HF is an exception.  Since F is the element with the strongest electronegativity (4.0) it forms very strong bonds.  And, apparently, water molecules just don't have the ability to break the H-F bond, so very little of HF ionizes in water.    Talking about HF, it is one of the few compounds (and as far as I know, the only compound) that can attack glass (Si03) to form fluorosilicates.

And H2O2 is hydrogen peroxide (that stuff you put on cuts and it fizzes)....cuz I can almost see that one coming....and H2O3 is dihydrogen trioxide a powerful oxidant produced by antibodies in reaction to invading bacteria in the body.....

Silica fume has a average size distribution from 0,3 to 0,05 microns (or less) with a specific surface area from 15 to 200 m2/g.\n\nFor more information see the web site of degussa.

Unless you are talking beauty supplies rather than chemistry.\n\nThen you mix the peroxide with bleach powder or dye to activate them.  10 volume is the weakest, therefore slowest.  50 volume is the strongest, fastest.

the water substance drowns the oxygen out of the "would be fire" in the hydrogen peroxide\n\nfire needs O2 to live

The photocatalytic properties of the glass' coating are energized by UV rays to help slowly break down and loosen organic dirt. \n\nThe hydrophilic properties cause water to sheet evenly over the glass surface, instead of beading. This sheeting action helps to flush the surface clean and to accelerate drying, leaving the glass with minimal spotting and streaking.

Silica gel is used to absorb water from a gaseous environment the water absorbing capacity is usually around 25% by weight, \n\nso it absorbs the water in human body causes dehydration

Peroxide. The simplest related neutral compound is hydrogen peroxide, H2O2, H-O-O-H. Take off 2H+, and you have O-O with a (-) on each O.

SiO2 (like standard glass) and it can be tainted with other materials depending on prospective use.

You can rinse with Hydrogen peroxide just like regular mouthwash. It tastes TERRIBLE though. You are better off getting some Listerine(c)

Silica is simply SiO2, so silica oxide really is no diferent than just silica.  Silica is very common in the world in the form of sand, and therefore doesn't usually need to be synthesized, although it is ustually ground and sieved to acquire only one particle size for abrasives.

Hmmm, what exactly do you mean by INSTRUMENTAL techniques? As the guy before me said, you could titrate it against a strong coloured oxidising agent such as acidifies potassium permanganate. But you can't really get the concentration from a spectrophotometer, for example, since peroxide (H2O2) doesn't absorb light.\nI guess you could thry using a NMR spectrometer for the job, or some kind of chromatography, but titration is by far the safest and easyest.

Light will have an adverse effect on hydrogen peroxide.  If you look on the bottle, there is an expiration date to this product.  This is when it is under ideal conditions (room temperature, dark).  If hydrogen peroxide was in a light or clear bottle, it would not last as long, and would therefore have diminished or no effect when you use it.

The oxygens are bonded together with the one hydrogen bonded to each oxygen.  It hydrogen peroxide and has 18 electrons

In terms of molecular weight, water would be H20 which according to the period table of elements would have a molecular weight of 18 while Hydrogen peroxide or H202 would have a molecular weight of 34.  (molecular weight of hydrogen is one, while that of oxygen is 16).  Thus hydrogen peroxide would be heavier.
