How does time affect the pH of orange juice?
Over time, the pH of orange juice can decrease due to the natural oxidation of the juice, which can lead to an increase in acidity. The longer the orange juice is exposed to air, the greater the chance of pH changes occurring. It's recommended to consume orange juice soon after it's been freshly squeezed to maintain its pH level.
Is squeezing lemon juice on fruit to stop it going brown a chemical reaction?
Squeezing lemon juice on fruit to prevent browning is not a chemical reaction, but rather a physical reaction. The citric acid in the lemon juice slows down the oxidation process that causes the fruit to turn brown by acting as an antioxidant.
Does hot orange juice make a nail rust?
Yes, hot orange juice can make a nail rust because orange juice contains citric acid, which can accelerate the oxidation process of the iron in the nail, leading to rust formation when combined with heat.
How does the pH of juice change with time How does temperature affect the rate of chemical changes?
The pH of juice can change over time due to chemical reactions such as oxidation and fermentation. Higher temperatures generally increase the rate of chemical reactions, so temperature can affect the rate at which the pH of juice changes. Higher temperatures can lead to faster degradation of components in juice, which can impact its pH.
What happens to the pH level in fruit juice when exposed to air?
When fruit juice is exposed to air, it can undergo oxidation, which may lead to a decrease in pH levels due to the formation of acidic compounds. The citrus fruits in the juice may release citric acid and other organic acids when exposed to oxygen, further lowering the pH level.

Why does lemon juice save an apple?
When exposed to air, apples turn brown due to oxidation. Lemon juice is rich in vitamin C, which is a natural antioxidant, and stops the oxidation process that turns apples brown when exposed to air. It also lowers the pH (making it more acidic) which is hostile to some of the common microorganisms.
