It depends on the type of ink used; there are several methods of using invisible ink and of finding them. The most common is to use a weakly acidic solution such as lemon juice; wipe this over the area thought to be hiding the ink and then heat it using a blowdryer, electric iron or oven on low heat. Another is to place the area under a UV light, as some inks will only show up under one.
The hypothesis of an invisible ink could be that the ink will become visible when exposed to a certain type of light or heat, based on the properties of the ink's chemical composition.
Lemon juice works as invisible ink because it is acidic and weakens the paper fibers, making the writing invisible until heat is applied. When the paper is heated, the sugars in the lemon juice caramelize and turn brown, revealing the hidden message.
Yes, baking soda can be mixed with water to create invisible ink. When the solution dries on paper, the writing becomes invisible and can later be revealed by applying heat or a second solution (such as vinegar).
In invisible ink, ammonia is typically used in a ratio of 5 parts ammonia to 50 parts of another liquid or solution. This concentration helps to reveal the invisible message when it is heated or exposed to certain chemicals.
Lemon juice works best for making invisible ink compared to baking soda. When heated or dried, the lemon juice oxidizes and turns brown, making the writing visible. Baking soda is not an effective choice for invisible ink as it does not have the same chemical reaction when exposed to heat or other substances.

The way invisible ink works depends on the method used to make it.

Invisible ink isn't actually invisible. The writing done with invisible ink is invisible, and can be read only after applying certain treatments. For example, orange and lemon juices are invisible inks. Orange and lemon juices are perfectly visible, but when you write with them, the text becomes invisible. The text can be read only if the paper is kept under ultraviolet light, or if it is slightly heated.
