When the ink is sprayed onto a porous material the water in the ink reacts with carbon dioxide in the air to form carbonic acid. The carbonic acid then reacts with the sodium hydroxide in a neutralization reaction to form sodium carbonate. Neutralizaton of the base causes a color change of the indicator and the stain disappears:
Carbon dioxide in the air reacts with water to form carbonic acid:
CO2 + H2O -> H2CO3
The neutralization reaction is sodium hydroxide + carbonic acid -> sodium carbonate + water:
2 Na(OH) + H2CO3 -> Na2CO3 + 2 H2O

How does erasable ink work and what makes it different from traditional ink?
Erasable ink contains special compounds that allow it to be easily removed from paper using friction or heat. This is different from traditional ink, which permanently bonds with the paper fibers.
How can ink stains be removed from fabric?
It depends on how much ink and what type of ink. I wear lab coat and usually work with black pen ink lines or occasional blot of ink. With this smaller amount ink, hairspray works best for me. I will work it or soak it depending on the ink's response to the stain.
What are ink erasers made of?
the erasers are normal the ink is special it has about 80% graphite
How do Frixion pens work to erase ink?
Frixion pens use special thermo-sensitive ink that disappears when exposed to heat. The friction caused by the eraser at the end of the pen generates heat, making the ink vanish.
What is vanishing color?
Disappearing ink is a water-based acid-base indicator (pH indicator) that changes from a colored to a colorless solution upon exposure to air. The most common pH indicators for the ink are thymolphthalein (blue) or phenolphthalein (red or pink). The indicators are mixed into a basic solution that becomes more acidic upon exposure to air, causing the color change. Note that in addition to disappearing ink, you could use different indicators to make color-change inks, too.
What is disappearing ink made of?
Disappearing ink is typically made from a combination of colorants, solvents, and compounds that allow the ink to become invisible after application. Commonly, it contains substances like phenolphthalein or other pH indicators that change color or become clear when exposed to certain conditions, such as changes in pH or evaporation of the solvent. The ink may also include water or alcohol as solvents to facilitate its application. Once the conditions change, the ink effectively disappears from the surface.
Does disapearing ink come off of everything?
Disappearing ink is designed to eventually fade or disappear over time, but it may not come off of all surfaces easily. It is recommended to test the disappearing ink on a small, inconspicuous area first before using it.

Why does the disappear ink appears in hot water when you pour veniger in hot wate?
Disappearing ink typically contains a substance like phenolphthalein, which is colorless in acidic conditions and turns pink in basic conditions. When you pour vinegar (an acid) into hot water, it alters the pH of the solution. If the disappearing ink is in a basic state, the vinegar effectively neutralizes it, causing the ink to reappear momentarily as the pH shifts. The heat may also affect the solubility and reaction rates, enhancing the visibility of the ink.
Is disappear an adjective?
No, disappear is a verb. The present participle disappearing is sometimes an adjective.(In Latin America, the Spanish word for "disappear" is used as a verb to mean extra-legal murder or detention, and the word disappeared is an adjective.)

However, some formulations may contain chemicals that could be irritating or harmful if ingested or used improperly. It's always best to check the label for safety information and use the product as intended.

How can I create disappearing ink using lemon juice?
To create disappearing ink using lemon juice, mix lemon juice with water in a 1:1 ratio. Use a cotton swab or a small brush to write your message on paper. Let the paper dry completely. When you want the message to disappear, heat the paper with a hairdryer or place it near a light bulb. The heat will cause the lemon juice to oxidize and the message will disappear.
