why do vinegar treated apples turn brown and lemon treated apples turn white?

its the oxygen that makes apples turn brown, when you treat them with lemon juice the oxygen cant touch the apple because of the juice layer.

Are you sure they're not beets?\nTry white vinegar It works on most things.\n\nI am inspired.\nMy Questions Have been fowl.\nI will try to ask something worthy of 30 points

Well, two reasons.  \nOne - ascorbic acid itself is easily oxidized.  Therefore, any oxidation which will occur happens to it first.  Once it is eaten up, it no longer works.\nTwo - there is a pH dependancy to the oxidation.  At lower pH (more acidic) the oxidation is much slower than at high pH.  This really doesn't depend on which acid it is.  Apples which are tart (like granny smiths) brown much more slowly than near-neutral onces (like red delicious).  The acid in question here is citric acid.

If you plan to leave out cut apple slices more than 15 minutes, squeeze a little lemon juice on them to keep them from getting brown.

Baking soda and vinegar are both wonderful natural cleaners!  Baking soda works well on stainless steel, porcelain, counters, etc.  Vinegar is wonderful on windows.  Together they make a good (strong) drain cleaner & freshner - pour bs down the drain then add apple cider vinegar - works great!

Vinegar is a solution of acetic acid (CH3COOH) in water. The best vinegar is produced from wine by acetic fermentation. And vinegar is acid with a pH aproximatively 4.5 - 5

Because each apple blossom can become an apple if it is fertilized.  If you pick the blossoms, it can reduce the apple yield of the tree, thus reducing the farmer's income.

The health benefits of apple cider vinegar can't be achieved with white vineger or any othe vinegar.  It isn't just that it tastes good, it has a different chemical makeup than the others.

Baking soda is a bicarbonate of sodium. Vinegar is mild acetic acid which is a weak organic acid. The two will react in a neutralization reaction to produce sodium acetate, water and carbon dioxide which is the gas you see. If you want to be certain it is CO2, then bubble it over lime water (saturated calcium hydroxide) and it will turn it cloudy.

This worked for me.  Take a glass or cup that you don't care about not using again, and fill it with apple cider or balsamic vinegar (or some sweeter kind).  Stretch a piece of plastic wrap across the top and secure it with a rubber band.  Poke a few holes in the top with a toothpick, and sit it in an out of the way place, preferably in the kitchen.  The fruit flies will fly in and be trapped, and the vinegar kills them.

if we are talking just Vinegar (acetic acid) and sulfur there is a possibility it would react to form hydrogen sulfide (H2S). H2S is toxic so you need to do it in small amounts and a WELL VENTILATED AREA!!!

Apple Cider Vinegar\n \n\nUse this diuretic in small quantities. You can add it to your salad as a dressing. What makes this such a powerful diuretic is this: It is made from apples and the malic acid in apples will create a fat burning process. Another factor with this vinegar is the fermentation process causes the vinegar to have constructive acids that join with alkaline elements and minerals in the body. This produces a cell scrubbing effect. \n\nIt also contains high levels of potassium, which has an antisceptic quality to that helps to eliminate fat deposits. \n\nBut like with anything, you should use it in moderation. :)

Lemon can not save Apple, Lemon can only Pray for Apple. Jesus Saves!

It's an acid catalysed hydrolysis. The oxygen attached to the 2-carbon is protonated, then acetic acid is displaced from the ring by water, which is deprotonated to give salicylic acid. The vinegar smell is acetic acid. Note that the reaction cannot occur without water.

muggy sulfur or burned vinegar or wet wood...depending on what I ate

the vinegar is a solution of water and acetic acid.  the acetic acid exists as acetate ion and hydrogen ion.  the bicarbonate is a sodium ion and a bicarbonate ion.  when the two combine, the postive hydrogen ion combines with the negative bicarbonate ion to produce carbon dioxide and water, and the negative acetate ion and the postive sodium ion combine (well, they really don't combine, they stay apart and disolved in the solution) to become sodium acetate.  what's left is a water solution with sodium acetate desolved in it and bubbles of carbon dioxide coming out of the solution.
