Miranda BadovinacMarch 20, 2018Introduction to Organic ChemistryPart 1:Objective:The objective of this experiment is to determine how acid and base affect a solutionconsisting of water and methyl violet indicator.Hypothesis:It is expected that when the acid is added, the solution will be a yellow colour sincethe pH will be lower than 1.6. When the base is added the solution will be a violet colourbecause the pH is above 1.6. Additionally, in the magnesium hydroxide solution, the metal willdissolve in an acidic solution and not in a basic solution, because when the acid is added it canreact with the hydroxide ions and from water allowing the reaction to proceed in the forwarddirection, but when base is added it will return to the original equilibrium.Variables:Independent – addition of acids and basesDependent – the way the reaction shiftsExperimental Procedure:1)Add 5 mL of water to a clean test tube.2)Add 3 drops of methyl violet indicator and record the colour of the original solution.
