Q:

What is the pH of table salt?

A:

By definition, pH is a measure of the hydrogen ions in an aqueous solution. As table salt, in its pure form, is not dissolved in water, it has no pH.

When one dissolves sodium chloride in water, the ionic compound dissociates into sodium ions and chloride ions. These ions do not interact with the hydrogen or hydroxide ions of water and thus do not affect the pH of the solution in which they dissolve. They do, however, affect other characteristics of the water. When mixed with sodium chloride in too great a concentration, water is no longer fit to drink.

    What is the pH of pure water?

    A:

    At 77 degrees Fahrenheit, the pH of pure water is approximately 7. The pH value describes the acidity or basicity of an aqueous solution. Acids have pH values of less than 7 while bases have pH values greater than 7. A pH value of 7 is neutral.

    What is the difference between salt and sugar?

    A:

    The difference between salt and sugar, specifically sodium chloride and sucrose, the particular salt and sugar most often used by people, is in their elemental composition, the types of bonds that hold them together and the way they dissolve in water. Salt and sugar can appear almost identical on casual inspection, both being white, crystalline solids. However, despite the fact that both are water soluble, they have vast chemical differences.
