INTRODUCTIONAcids and bases have always challenged me during the years I have studied them, so when I knew I would be tackling this topic again I thought it would It was the best idea for a better learning experiment so my goal for this project was to learn the fundamentals of this topic. Acids and bases are really important in the functioning of the cell. Most of them are harmful and destroy tissues by dissolving proteins. For example, sulfuric acid is a strong acid and has the ability to retain water so if poured onto living tissue it will be immediately destroyed. Aqueous solutions of bases react with fat in the cell membrane, making bases more devastating to the body than acids. Aqueous solutions of acids and bases conduct electricity. Acids taste sour, bases taste bitter, and bases are slippery. The strength of an acid or base depends on its ionization rate. Strong acids and bases are completely ionized and therefore have a pH or pOH equal to 1, weak bases and acids are not completely ionized therefore have a pH or pOH equal to 3-5.Theories of acids and basesUp to today acids and bases defined in many different ways but the first modern description was made by the Swedish scientist Svonte ARHENIUS in 1884. He said: Aqueous solutions of acids give H+ ions. For example:NaOH → Na++ OH−eAqueous solutions of bases give OH- ion for exampleNaOH → Na++ OH−The second description of acids and bases was found by the Danish chemist JN Bronsted and the English chemist TN LOWRY in 1923. According to them the matter that gives protons are acids and matter that receives protons is base. With this description what is not thought of as an acid or base is now classified as an acid or base. For example, boron trifluoride acts as an acid and...... middle of the paper... titration is a neutralization reaction. In the acid-base titration solution with no known molarity, it is placed in an Erlenmeyer after its volume has been measured. An indicator is added to the solution, in most cases it is phenolphthalein. The solution with known concentration is placed in the burette with a stopcock at the end. By slightly opening the tap, the solution in the burette is poured drop by drop into the Erlenmeyer solution. After a while the Erlenmeyer solution forms a color change. This is the turning point for the solution. At the turning point based on the volume consumed in the burette, the molarity of the other solution can beIndicatorsIndicators are substances that change color based on the acidic and basic properties of the surrounding environment. There are many different indicators that show different pH levels and some are beyond the chart.
