Oil-based food coloring used to make the letters, won't dissolve in water. According to some sources, oil-based food coloring is either insoluble or immiscible in water. Because it is present in more solutions, water serves as the universal solvent.
<h3>
Universal solvent:-</h3>
A substance that displaces most compounds is known as a universal solvent. Because it dissolves more chemicals than any other solvent, water is known as the universal solvent.
<h3>
What chemicals lack solvability?</h3>
Sand, plastic, wood, metal, glass, and cloth are examples of insoluble materials. At standard conditions of pressure and temperature, these compounds never dissolve in water or any other solvent. Other examples of insoluble materials are sugars and inorganic salts.

A- and H3O+ interact, causing A-'s concentration to drop and [HA] to rise. As a result, the [NaA]/[HA] ratio declines. Because of the base content, the buffer's pH will be more acidic. The concentration of the acid, HA, has increased while A- has decreased.
What is Acid?
Any material that when dissolved in water has an acidic taste, can alter the colour of some indicators (such as reddening blue litmus paper), can react with some metals (such as iron) to release hydrogen, can combine with bases to produce salts, and can accelerate some chemical reactions (acid catalysis). Acids are examples of organic chemicals that belong to the carboxylic acid, sulfonic acid, and phenol groups as well as the inorganic substances known as the mineral acids, such as sulfuric, nitric, hydrochloric, and phosphoric acids. These chemicals contain one or more hydrogen atoms, which are discharged as positively charged hydrogen ions when they are in solution.
