Using Beers law what will bleach out grape juice faster regular bleach or hydrogen peroxide?

Ummm...You will have to figure out which is faster... but I can give an idea as to proceedure...First, try to answer this question: What are all the colored species in grape juice? You need to know that first. Hopefully there is only one. That would simplfy things. Then you need an extinction coefficient for that compound, if you can find one. Using that, you can take several absorbance measures and use Beer's law to establish the concentration of that species in your stock solution. Beer's law states that Absorbance = extinction coefficient x concentration x path length. Your path length is the width of your cuvette, which is usually 1 cm. Beer's Law will not be valid if you use a solution that is so concentrated that it gives you an absorbance value greater than 2. At Absorbance = 2, well over 99% of light is being absorbed. A reading over 2 is thus considered analytically unusable. Your juice can be diluted, if necessary, with DEIONIZED (aka distilled) water. Once you do that, I would roughly time each reaction by just looking at it with my eye, adding just a drop or so of bleach/peroxide initially, and increasing the amount only if necessary. Make sure to add exactly the same amount of bleach/peroxide to exactly the same volume of grape juice. Once you have the reaction basically set up to your satisfaction, then place your juice sample in the colorimeter and get ready to add your reagent. Remember to take a measurement before you add any bleach/peroxide for EACH of the two tests. And take your measurements on the same time frame (ex: every 30 sec.)Good Luck!!! :-)

Mouthwash witrh a high alcohol content, or hydrogen peroxide...if not you're out of luck

There is an easy one using enzyme catalysis.  Use hydrogen peroxide solution from the local pharmacy or grocery store.  Put some in a test tube and drop a fresh slice of potato in it.\n\nThe potato has catalase enzyme in it.  This enzyme catalyses the decomposition of hydrogen peroxide to water and oxygen as such:\n\n2 H2O2  >(Catalase)> 2 H2O + O2\n\nThe activity of the enzyme catalyst can be observed by the bubbles of oxygen gas that form during the reaction.

1 tbsp baking soda and 1/2 tsp lemon juice this will whiten and does not have the explosive properties of baking soda and hydrogen peroxide

Hydrogen peroxide is the best!!

Bleach it has way more action

Drink a glass of orange or grapefruit juice, adding acid to digest faster.

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.

hydrogen peroxide slowly breaks down into water and oxygen. blood contains a catalyst called catalase. when the hydrogen peroxide comes in contact with catalase, it speeds up the breakdown. you are basically seeing oxygen breaking apart from water. sunlight also speeds up the reaction. (thats why it comes in a brown container);)

"The best home methods are baking soda or hydrogen peroxide. "\n\nBaking soda can really ruin your teeth over time because it's\nso gritty. \n\nHydrogen Peroxide is a 'bleach'. Many dentists and their assistants will recommend hydrogen peroxide to you.\n\nI have been told however that the problem with hydrogen peroxide is that it will turn your tongue brown. Your tongue has these little hairs on it. The hydrogen peroxide aids in their growth.\n\nIf you want a little furry rug on your tongue then go the hydrogen peroxide route. \n\nNeither method is a suitable replacement for brushing your teeth\nand flossing.\n\n" eating fresh crunchy veggies and fruits such as: carrots, broccoli, celery, apples, strawberries, and cucumbers can help whiten your teeth. I've worked in the dental field for years and have seen many teeth damaged because people thought that brushing with baking soda or eating lemons whitened their teeth."\n\nhttp://www.otan.dni.us/webfarm/emailproject/white.htm

You'll need lots of grapes to add to the water, then you'll have to put the grapes and water into a big vat.(tub) Take off your shoes and socks and walk all over the grapes to crush them. Let this concoction ferment for about 20 days, daily walking in it with bare feet to keep it stirred. After fermentation, pour in jugs and cork. By the time you do all this, you'll be to tired to walk on water. :D

water, rubbing alcohol or if nothing else acid :P(dont really do acid)

None. They are two different compounds.\n\nIt looks like you want to compare a specific property of the alcohols. Please specify!

Avoid coffee and red wine as much as possible. Both will quickly stain your teeth,Strawberries have a natural bleaching effect and are loaded with Vitamin C, so you simply can't lose. Rub the pulp over your teeth and then rinse, Brushing your teeth every 12 hours,Lemon peel massaged over the teeth is often used for whitening. Rinse thoroughly,Avoid smoking,floss at least once a day.thank you

Hydrogen peroxide is a very strong oxidizing agent, read, very reactive.  When it mixes with nitrogen it releases heat by chemical reaction (that's also what happens in a combustion engine like a car).  And it makes water.  The heat would make the water into steam and in an enclosed system the increase in the volume will creat pressure, like when you warm up water for tea and it has to escape by blowing through the hole with high speed.  I hope that makes sense.  I'm trying for laymens terms.  I am not sure I succeeded.

To bleach something is to remove or lighten its color; a "bleach" is a chemical that can produce these effects, often via oxidization. Common chemical bleaches include sodium hypochlorite, or "chlorine bleach," and "oxygen bleach," which contains hydrogen peroxide or a peroxide-releasing compound such as sodium perborate or sodium percarbonate. "Bleaching powder" is calcium hypochlorite. Bleaching may be a preliminary step in the process of dyeing.\n\nHousehold bleach or sodium hypochlorite is used in the home for whitening clothes, removing stains, and disinfecting. This is because sodium hypochlorite yields chlorine radicals—oxidizing agents readily reacting with many substances.\n\nHair bleach contains H2O2 (hydrogen peroxide), which gives off oxygen radicals as it decomposes. Oxygen and chlorine radicals both have comparable bleaching effects.\n\nChlorine bleach is often used with laundry detergent and is also commonly used as a disinfectant by homemakers and janitors. Mixing bleach and cleaners containing ammonia, or using bleach to clean up urine can create toxic chloramine gases and an explosive called nitrogen trichloride.\n\nNot all bleaches have to be of oxidizing nature. Sodium dithionite is used as a powerful reducing agent in some bleaching formulas.\n\nChlorine dioxide is used for the bleaching of wood pulp, fats and oils, cellulose, flour, textiles, beeswax, and in a number of other industries.\n\nIn the food industry, some organic peroxides (acetone peroxide, benzoyl peroxide, etc.) and other agents (e.g. bromates) are used as flour bleaching and maturing agents.

Tip of the day:  been drinking red wine all night, and afraid of stained teeth?  No problem -- simply drink a bottle of white wine before going to bed to eliminate those red wine stains.\n\nNow, in answer to your question --\n\nIt's just that white wine acts as a solvent, and white wine is clear -- having no color pigments to deposit as does red wine.\n\nYou can also use distilled vinegar ("white" vinegar) or peroxide (test fabric in inconspicuous area for colorfastness) to achieve the same result.\n\n\nNo winos were harmed in the answering of this question.
