Standard Basic Solution

Loui Abodeeb Chemistry lab 1107 Lab report November 1, 2011 Lab 11: exampleized a basic termination Solutions are uniform mixtures consisting of one or more solutes dissolved in a solvent. In give to describe a answer, we need to have intercourse its composition and its corporeal state. From the composition of the declaration, we find out the chemic identity of the solute or solutes and the solvent, as well as their densenesss. mebibyte is one of the most common ways to express the concentration of a settlement is called standardization of a result. Therefore, a standard solution is a solution with a known concentration. Titration is a method use to standardize solutions. In this method, we use a standard solution whose concentration is known to determine the concentration of another solution whose concentration is unknown. Titration is carried out by the accession of a solution from a buret to another solution in a flask until all the substance in the flask h as only reacted. The solution rendered from the buret is called the titrant. In do to determine when the neutralisation reaction reaction is complete, you will add an acid-foundation indicator. This is a compound whose emblazon changes when the pH of a solution changes upon additions of an acid or a topic.

The indicator had been used is called phenolphthalein whose colouration is clear if the solution is acid-forming and turns pink when the solution becomes basic. The colorize changes when it reached an equivalence point, which happens when the number of moles of the base equals the number of moles of the acid. This experiment has trinity steps: 1. Titration. 2. Standa rdizing an NaOH solution. 3. Acid base ! titration.
