What changes did you notice in the color of the apple?
Answer. Explanation: Apples turn brown when exposed to air because of the oxidation process that goes on when the inside of the apple gets exposed to the ambient air which contains oxygen and water molecules. The skin of the apple protects it from this process.
Did the Apple change its color when bitten?
The story: When you bite or cut into an apple you’re breaking open tiny apple cells. Enzymes and compounds that the cell had kept separate from each other suddenly mix together. Add some oxygen in the air to the equation and the resulting chemical reaction leaves us with this brown color.
What does this discoloration of Apple mean?
Why do apples brown? Secondary browning generally refers to discoloration that occurs when an apple is beginning to decompose due to fungi and bacteria. In other words, when the fruit is rotting. Primary browning in apples takes place when the fruit’s phenolic compounds react with oxygen.
When you slice an apple what happens to its color?
When an apple is cut (or bruised), oxygen is introduced into the injured plant tissue.

What will happen if you put lemon on an apple slice?
The longer the enzyme is exposed, the browner each slice will become. Lemon juice contains citric acid, which is a natural anti-oxidant. Therefore, when you apply lemon juice to apple slices, it helps to prevent the oxidation process. This simple step should keep your apples from browning for several hours.
What will happen if you put milk on an Apple?

What is the effect of putting vitamin C in an apple in glass be?
This is because vitamin C is an antioxidant that reacts with the very reactive oxygen-centred radicals, turning them into less reactive species. Hence, this reduces the amount of oxidative damage to the apple flesh. This is why the apple in the vitamin C solution does not turn brown and remains fresh looking.
