Is there an easy  test  for the acidity of paper?

Apart from the precipitation reactions (AgCl and BaCO3 form insoluble compounds, although HCl will dissolve BaCO3), there is flame colouring for identifying the alkali and earth alkali metals (Na yellowish orange, Li reddish, Ba green), there are pH measurements (HCl acidic, NaOH and Na2CO3 basic, rest neutral), and you need to test an oxidant to identify the sugar solution. This ought to give you a matrix which gives only one possible identification for each test (with deionized water failing all tests).

A simpler formula will be SO2+NO2+CO2+H20 (unlimited)-> H2SO4 (strong and oxidant) +  HNO3 (nitric acid, stronger and oxidant) +  H2C03 (carbonic acid, weak but ´till corrosive, just like the soft drinks)

smell the paper.\n\n\nGood luck!

This depends on the dimensions of the post it note, and also the side from which you are measuring the peel strength.  but typically the peel strength is between 5 and 15 grams metric.\n\n  An easy way to measure this is get a tall stack of post-it notes, sit it on a table and peel sheets off by holding only the sheet being peeled.  Continue peeling sheets until you pick the stack up by the sheet you are peeling ..  then measure the weight of the stack.  Repeat this several times to get a solid average.

There are several ways to make paper look old, here are just a few.\n\nSpread milk all over the paper and put it in the oven at 360 degrees for a half a hour to a hour. WARNING - Keep an eye on the paper during this process in case it catches light!\n\nDab the edges of the paper with water, then use a lighter or candle to char the edges. \n\nMake 1 pot of dark coffee with no sugar or milk. Combine it with 5 or more teabags and then leave the coffee to settle for about 2 hours to 2 hours and a half. Then take a paintbrush and paint over the paper with the coffee and tea and then let it dry over night between 2 white pieces of paper. \n\n\nMake a pot of tea and keep it warm \nCrumble the paper up and dip it inside the tea \nUse a match to light the edges of the paper \n\n     There you go! One historic looking document!

From what I can find out, it appears to be slightly acid, approaching neutral, pH 5-7\n\nHow cool is that?! It's like that question was designed just for someone with my name!

GOLD-PLATINUM-PALLADIUM TEST\nBy Delos Toole\n\nSelect ore samples suspected to contain Gold-Platinum-Palladium and use concentrates equal to the size of one navy bean or pea. Place the concentrates in a clean test tube and add 1cc Nitric Acid and 3cc Hydrochloric Acid, (this a solution named Aqua Regia which is used regularly when testing.) Boil this over a lamp flame for about 5 to 8 minutes. Should this Aqua Regia solution contain Gold-Platinum-Palladium then the following tests will react with various colors, (good idea to practice on known samples of Gold-Platinum-Palladium for color and reaction identification and become familiar to them.)\n\nTest for Gold (Au).\n\nPrepare a solution for Stannous Chloride for each 8 hour period as this solution does not hold up under extended time periods. Dissolving Metallic Tin (Sn) in Hydrochloric Acid (HC1), where the resulted solution will be called Stannous Chloride (SnC1). Place about 2cc of HC1 in a clean test tube and add 1 or 2 small bit pieces of Metallic Tin to the test tube and bring this to a slight boil. You now have Stannous Chloride (SnC1).\n\nNow begin the gold test by making a spot test with freshly made Stannous Chloride by placing a piece of filter paper onto a clean piece of glass and place one drop of Aqua Regia solution in the center of the filter paper, and then add to this mixture one drop of freshly made Stannous Chloride solution. If gold is present there will show up on the filter paper a purple or rose colored spot when the filter paper has dried; the darker the color the more gold will be present; for low grade ore the spot color will appear plainer. Should the filter paper dry out completely, then add 1 more drop of Stannous Chloride solution to the filter paper to bring out the color.\n\nBegin the test for Platinum (Pt) by placing 20 drops of Aqua Regia solution onto a clean porcelain evaporating dish and boil this over a lamp flame until it is dry, then allow this to remain over the lamp flame for about an extended one second.\n\nPlace the dish where it can cool for a few minutes so as not to break the dish. After cooling, place 4cc of distilled water, (or water free from Chlorine), and reheat just to the boiling point. Filter this solution onto another clean porcelain evaporating dish. Add to this dish, Potassium Iodide equal to one grain of rice. Warm this solution slightly over the lamp flame and observe the color that appears. The results for this test will show if Platinum (Pt) is present as the solution will begin to turn to a light or dark rose color within a few minutes time.\n\nThe more Platinum present in the solution, (ore sample), the quicker and darker the color will appear.\n\nSulphides and other impurities, most likely will give a red color to the solution and will be mistaken for the rose color, if so, then boil off about one-half of the solution to quicken the evaporation process. Then let the porcelain dish set until completely dry, then add a few drops of clean plain water, (no chlorine water). The result will then be a bright rose color, and should there be Sulphides or other impurities in the solution they will appear as colorless. If this solution should appear red, then add a few cc’s of plain water to dilute the dark rose color to a lighter rose color, then you have Platinum (Pt).\n\nTesting for Palladium(Pd).\n\nIn the test for Platinum (Pt), upon adding Potassium Iodide (KI) and warming the procedure, if Palladium (Pd) is present in the sample ore, the solution will turn a dark color or black, which depends upon the amount of Palladium (Pd) present. The more Palladium (Pd) present, the darker the color will be, and also there will be a black precipitate in the bottom of the porcelain dish, which when adding an excess of Potassium Iodide (KI) will dissolve giving a wine-red color appearance.

let me tickleyou_there, alternatively try vinegar and brown paper

there are many diferences:\n1)acid turns litmus paper blue to red while base turns litmus from red to blue\n2)acids produce H+ ions in aqueous solutions \nbases produce OH- ions in aqueous solutions \n3)acids are proton donors \nbases are proton acceptors

The simplest way is spectography. if you are speaking of a breathalizer test it is via conductivity.

Most definetly acidic

fairly easy, not 100% ionized but increases the concentration of H+, obviously a weak acid ^^

Acetic acid is a fancy name for vinegar...if you mix it with baking soda it fizzes, that's evidence of acidity... also you can mix it with hydrogen peroxide. I can't think of an easy third test...maybe ammonium nitrate... all these tests would involve litmus paper by the way.

Identification test for Citric Acid:\n\nAdd a few milligrams of your substance to a solution containing 15mL of pyridine and 5mL of acetic anhydride.  If citric acid is present, a bright red color is produced.

It's easy. Spot ink onto a tissue paper. Dip one end of the tissue paper in a pan with any alcohol. Let the alcohol travel along the paper and make sure it passes through the ink spot. Some components of ink which are attracted (more soluble) to alcohol will be carried with the solvent but will eventually settle somewhere else in the paper. Let the alcohol evaporate and you can see the ink components, more or else, separated. A more scientific way of doing the analysis is by chromatography: thin layer chromatography (TLC) or gas chromatography (GC). Check the web.
