Acids, Bases, and Neutrals
Problem
Are common house-hold products pH balanced and neutral?
Information Gathered
pH measures how acidic or alkaline a solution is. The pH scale ranges from 0-14. Solutions that range from 0-6 are considered to be acidic. Solutions that are on the acidic end of the scale are low in pH, high in hydrogen ion, and low in hydroxyl ions. An acid has a sour taste, hence, will react to metal and will be corrosive; therefore, they are considered as an electrolyte because it conducts an electrical charge. Such examples of acids that are hydrochloric acid, citric acid and vinegar. Solutions that are bases on the pH scale range from 8-14. Bases are high in pH, low in hydrogen ion and high in hydroxyl ion. Bases have a bitter taste and a slippery feel. Bases dissolve in water and are also an electrolyte. Examples of bases are sodium hydroxide and cleaning products. Solutions that are neutral have an equal amount of hydrogen ion and hydroxyl ion. An example of this is blood. Solutions that are neutral on the pH scale range are 7.
Hypothesis
It has been estimated that out of the first ten products, that five of them would be bases, three would be acids, and two would be neutral. It was also estimated that out of the last ten products, that nine of them would be acids and one would be a base. There was an estimation of twenty products.
The Essay on Liter Of Solution Base Acid Solutions
Introduction: In 1909 S. P. L. Sorensen published a paper in Biochem Z in which he discussed the effect of H 1+ ions on the activity of enzymes. In the paper he invented the term pH to describe this effect and defined it as the -log[H 1+ ]. In 1924 Sorensen realized that the pH of a solution is a function of the 'activity' of the H 1+ ion not the concentration and published a second paper on the ...
