Because a lemon is a citrus and an apple is not.....
i would say dawn but lemon juice cause it is an stronger acid.
lemon juice
Lemon juice with a pH of 2.5 is a stronger acid compared to tomato juice with a pH of 4.5. pH is a measure of the concentration of hydrogen ions in a solution, and the lower the pH value, the higher the acidity of the substance. Therefore, lemon juice would be considered a stronger acid in this scenario.
The apple will be fresh longer. Since the acid in the apple makes the apple turn brown the lemon juice keeps it from doing that.
Applying lemon juice to sliced apples helps prevent oxidation.
Stomach acid, also known as gastric acid, is stronger and more acidic than lemon juice. Stomach acid has a pH of around 1.5 to 3.5, while lemon juice typically has a pH of around 2.0 to 2.6.
Lemon juice does not turn an apple red; instead, it helps prevent the apple from browning when exposed to air. The citric acid in lemon juice slows down the oxidation process that causes the apple's flesh to turn brown. If an apple appears red after applying lemon juice, it is likely due to the apple's natural color rather than a change induced by the juice.
because on the pH scale lemon juice show it is more stronger than vinegar. The pH of the lemon juice is 2,3 (because of cirtic acid (53,3 g/l) and malic acid(3,5 g/l)) and The pH of table vinegar ranges from 2.4 to 3.4. That's why lemon seems stronger.
Lemon juice contains an acid (but by itself it is not an acid, because it is not a pure compound): citric acid makes lemon juice acidic.
Among the options provided, hydrochloric acid (HCl) is the strongest acid. Vinegar and lemon juice are both weak acids, with lemon juice being slightly stronger than vinegar due to its higher citric acid content. Blood is neutral, with a pH close to 7, making it much weaker than the other acids listed.
A car battery has a stronger pH compared to lemon juice. Lemon juice typically has a pH around 2, which is acidic, while a car battery has a very low pH due to the strong sulfuric acid electrolyte it contains.
Lemon juice contains citric acid.
