Acid base titration using method of double indicators essay

acid base titration using method of double indicators essay To determine the concentration of the hcl solution using acid-bade titration and verify if the molarity is equal to 15 mol/l materials: apparatus - standardized naoh solution - 250 ml beakers (2)  - unknown concentration of hcl solution - 50 ml burets (2) - phenolphthalein solution - double buret clamp.

Objective: to understand the importance of choosing suitable indicators for detecting the end points of acid-base titrations to obtain titration curves some acid-base titrations materials and method: as shown in page 2 and 3 in general chemistry practical manual 2011. This was one of the limitations in this acid-base titration lab as the indicators that were used did not show a change in color at an exact value of ph but only changed in a specific range of the ph for example, the indicator bromocresol green changes the color of the solution of a ph range between 38 to 54. Acid base indicators in the strong acid-weak base titration, 0 1 m ammonium hydroxide ( nh4oh ) was titrated with 0 1 m hydrochloric acid ( hcl ) 2 drops of phenolphthalein were added as indicator into the conical flask which contains 25ml of hydrochloric acid, the mixture in the conical flask was colourless.

  • I have concluded that the of acetic acid is -5±2% just using the data recorded (method 1) however from using that data and calculating the ph of acetic acid and naoh, and then plotting a titration curve (method 2), we got a of 48±02.
  • Acid based titration: determination of the concentration of an unknown acid or base by neutralizing the acid or base with an acid or base of a known substance redox titration : type of titration based on a redox reaction between the analyte and titrant which involves the use of a redox indicator and/or a potentiometer.
  • Introduction 11 aim the aim of this investigation was to determine the precise molarity of two (naoh(aq)) sodium hydroxide solutions produced at the beginning of the experiment through the acid-base titration technique 12 theoretical background titration is a method commonly used in laboratory investigations to carry out chemical analysis.

I objective: the purpose of this experiment is to determine the composition of a mixture of solutions of naoh and na2co3 by double indicator method. Acid-base titration - acid-base titration i abstract the purpose of the laboratory experiment was to determine equivalence points, pka, and pkb points for a strong acid, hcl, titrated with a strong base, naoh using a drop by drop approach in order to determine completely accurate data. Run the acid into the solution until the volume of hcl is to within 2 cm3 of what it was in the rough titration (step 5) ii) at this point run the acid into the solution at a slower rate (dripping it in slowly and shaking the solution in the process) so you can read the volume of hcl required to neutralise the solution to one drip (005 cm3.
