In paint industry the reducing strength(r.d) of Tio2 is greatly considered.I need a method to find the r.d?

As no one else has had a crack at this, I'll have a go with my best guess. Have you access to a reflectance spectrophotometer? Instead of shining light through a sample, it measures light reflected from a sample. At a pinch, you might be able to modify a uv/vis spectrophotometer to measure this.\n\nI hope this helps.

I would say d because they are antioxidants.  see article below for more info:\nhttp://chemistry.about.com/library/weekly/aa082101a.htm

You want us to calculate acitivites?\n\nYou need to determine the ionic strength and atomic radius in order to do that.

Flouropolymers are inert, meaning they don't react with other chemicals.  They also have the lowest known friction of any material (run your finger or slide a glass across a well varnished bar or table and you'll know what I mean)  They Contribute to paint's stain resistance by forming a sort of shield inside the paint (because they don't chemically react) and also give you some very shiny paint.  You can find a lil more about different polymers at my source link...  Good luck

If the reaction goes to fast, i.e.the blue colour appears instantly, you can slow it down by adding more thiosulfate to the solution.\n\nI hope that helped, because otherwise the meaning of your question wasn't very clear to me.

decrease\nthe greater the surface area of the reactant the more it is exposed to its other reactant, and more of it can react,  thus the reaction rate increases. This is the opposite for a decrease in the surface area.

The easiest way to find out the answer to that question is to look up the MSDS.  It gives all the information you need about it's toxicity, reactivity, etc.  A lot of chemical supply companies have MSDS on their websites, and I think there might be a government website that has MSDS accessible online, but I'm not sure.

Here is a good guide\n\nhttp://dbhs.wvusd.k12.ca.us/webdocs/Stoichiometry/Limiting-Reagent.html

You are looking at a displacement reaction, in which the more reactive metal (Cu) is displacing the less reactive metal (Ag) from its salt solution (AgNO3).\nCu (s) + 2AgNO3 (aq) --> 2Ag (s) + Cu(NO3)2 (aq)\n\nHope this helps. :)

1)The rxn for art restoration is oxidation, which is part of the redox rxn. \n2-3) Oxidation is used in the production of cleaning products; and these products can be used for art restoration.

The company I work for does Salt Spray Analysis. it's used to find out how well a coating holds up under controlled conditions. Salt water is very corrosive to most metals and is a good medium for testing for corrosion.\n\nBasically, a part that has a coating (paint, Anodize, Nitride, Black Oxide,...) is placed in a sealed tank. The tank sprays water with a particuar amount of salt in it into the chamber. The parts are checked every hour, 2 hours, 6 hours...as directed by the requirements. As soon as ANY rust is found, the testing stops and the amount of time it took for the rust to show is recorded. 300 hours is very good for any type of paint.

Inductive reactance can be calculated using this formula: XL = 2πfL\n\nGood Luck

When an analyte that is a reducing agent is titrated directly with a standard iodine solution, the method is called "iodimetry".\n\nWhen an analyte that is an oxidizing agent is added to excess iodide to produce iodine, and the iodine produced is determined by titration with sodium thiosulfate, the method is called "iodometry".

Your question is incomplete.  What type of stains are you talking about?  Looking at the properties of the stain and you may find the answer you need.
