Abstract The purpose of this experiment is to determine the concentration of acetic acid in vinegar by using 0.1 M HCl and NaOH solution. By performing three titrations to determine the concentration of the base‚ the concentration of the acid was determined to be 0.600 M. It was possible to determine its concentration by standardizing the sodium hydroxide solution used for the first three titrations and by using phenolphthalein to indicate its equivalence point. In conclusion‚ although there were

William Piumbroeck Chem 214 Acid-Base Titration‚ Determination of Carbonate and Bicarbonate in a water sample Introduction The purpose of this lab is to determine the concentration of two bases‚ carbonate and bicarbonate‚ by using a potentiometric titration. We can determine the concentration of the bases in the reactions ( H+ +CO3- < ==> HCO3- and H+ + HCO3- < ==> H2CO3-) by the way the pH of the solution changes. The way the pH changes when a strong acid is added can

Titration Lab A Titration is a process of the concentration of one solution being determined by its reaction with either a standard solution or a known quantity of solid dissolved in solution. It may also be used to calculate the molar mass of an unknown acid or base. Purpose: I. Prepare a standard solution of sodium hydroxide II. Standardize a sodium hydroxide solution by using potassium hydrogen phthalate (KHP) III. When given whether the acid is monoprotic‚ diprotic‚ or triprotic

It affects the titrant value because the end point of the complexometric titration is determined by what I perceived as; therefore I should use a colorimeter or other computerized measurement devices instead. Lastly‚ there was a large amount of hydroxy naphthol blue indicator (HNB) being used for complexometric titration. The HNB indicator affects the volume of solution and hence the concentration in the solution due to the large volume of indicator

The Determination of the Concentration of Hard Water Ions by the Titration of EDTA By Hannah Denby Lab partners: Heidi Kiziah‚ Leonie Hamel University of Central Florida‚ CHM 2046L December 3rd‚ 2015 Abstract. The “hardness” of water is a common dilemma attributed by high concentrations of metals such as calcium and magnesium. This is a result of the properties of water; because it is a good solvent‚ impurities are easily dissolved. As water moves through soil and rock‚ it dissolves minute amounts

This is one of the most interesting questions scientist ask why does this chemical reaction happen when you mix this stuff together . Why do baking soda and vinegar react with each other? This happens because of an acid base reaction and also because baking soda is a bicarbonate and vinegar is an acid and when you mix them together fiss start to show up . What does this have to do with my science fair project? This has to do with my science fair project because it shows how the volcanic

remaining solution in the buret and record it. 9. Position the buret over the Erlenmeyer flask so the tip of buret is 2cm above the liquid. 10. Add three drops of phenolphthalein solution to the KHP solution in the flask. 11. Begin the titration by adding 1.0 mL of NaOH solution to the flask and swirl the flask to mix the content. 12. Repeat this step until 15mL of NaOH has been added to the flask. 13. Reduce the incremental volumes of NaOH to 0.5 mL until pink color persists. Reduce
