 * A STUDY OF WHAT LIQUIDS MAKE DISAPPEARING INK DISAPPEAR BASED ON THE AMOUNT OF ACID IN THE LIQUID **

**ABSTRACT**

The purpose of this study was to determine what types of liquids make disappearing ink disappear fastest. Disappearing ink disappears because when carbon dioxide mixes with water the carbon dioxide turns into an acid. Different types of acidic liquids and three bases were mixed with water and then applied on the disappearing ink to determine which acidic liquid and base decreased the disappearing time of the disappearing ink the most. After experimenting it was determined that the more acidic the liquid was the less time it took for the disappearing ink to disappear. Acidic liquids made the disappearing ink disappear the fastest because the disappearing ink disappears when carbon dioxide turns into an acid and when more acidic liquids are applied to the disappearing ink it creates more acid making the disappearing disappear fast.

**EXPERIMENTAL IMPROVEMENTS AND FUTURE EXPERIMENTS** An improvement that could be made to make sure that the volume of the disappearing ink stayed the same throughout the experiments tested. By making this improvement the results of the different experiments would be easier to compare because the amount of disappearing ink tested was the same. In the future it would be interesting if instead of testing different acids and three simple bases to test more complex bases.
