Introduction
The solubility depends on the properties of a solvent that will allow interaction with a solute more strongly than do solvent particles together. Water is the universal solvent. Water, certainly dissolves many types of substances and in greater amounts than any other solvent. The salt is a compound consisting of various minerals, and is one of the most abundant elements on earth. It is formed out of sodium and chlorine. These minerals are considered electrolytes due to it electric possess. Baking Soda is a white, water soluble powder. On the pH scale of zero to 14, sodium bicarbonate is in 8.2. This substance is a basic. Sodium bicarbonate powder is a chemical whose molecular compound includes a sodium atom (Na), a hydrogen atom (H), a carbon atom (C) and three oxygen atoms (O). LifeSavers are a traditional American brand of hard candy. A lifesaver is a mix of sugar, corn syrup, high fructose corn syrup, natural and artificial flavors, citric acid and natural and artificial coloring. The purpose of this laboratory is to demonstrate in which solution the LifeSaver dissolves faster within five minutes. Materials

Water
Salt
Baking Soda
Regular LifeSaver hard candy
Cups
Watch settled for 5 minutes
Observations
The Lifesavers are round shape, purple color, solid and hard and 2cm size. Water is clear at room temperature. Salt and Baking Soda are in it solid state with power appearance. Question
Which solution will dissolve the LifeSaver the most within five minutes? Hypothesis
Because the molecular compound of the baking soda is higher than the water and the salt, the physical constitution of the sugar in the lifesaver must yield to the solution. The Lifesaver will dissolve most in the solution of the Baking soda. Alternative hypothesis

The salt is highly soluble in water. It...
