acid-base titration curves help to find the pKa‚ Ka‚ and pH at equivalent point. At the beginning pH for HCl is 1.90 which is lower than the 3.28 for acetic acid; thus‚ strong acid (HCl) means lower pH and weak acid (acetic acid) means higher pH. Then at the equivalent point for the titration HCl-NaOH the pH is 7‚ which mans that is neutral‚ in other words there are enough NaOH mmol to neutralize the HCl mmol present; also‚ the solution contains only water and NaCl the salt derived from the titration made

alcohol and acid by the concentrations of ester and water. Methods/Procedure: First begin by mixing up and standardizing a 500mL solution of NaOH to titrate. For each of the six bottles‚ measure the directed amounts of ester‚ water‚ alcohol‚ and HCl. The bottles of different solutions will be left to come to equilibrium for two weeks. Once the NaOH is standardized‚ the solutions in the bottles have come to equilibrium‚ and a molarity is calculated‚ use the molarity of NaOH to discover how many

NaOH according to this equation: HCl (aq)+ NaOH(aq) → NaCl(aq) + H2O(l) HCl is a strong acid‚ NaOH is also a strong base‚ therefore they will dissolve completely. By adding NaOH into HCl‚ the hydrogen ions neutralized with hydroxide ions‚ the theoretical endpoint and then the solution will be weak basic solution. The endpoint

For the buffer 2 solution‚ the original pH was 5.82 with 10mL of buffer and 10mL of DI water. We added 1.5mL of NaOH this time‚ and the pH went up to 7.81. This is a difference of 2. 2. What is the difference between a’smart’ and a’smart’? For adding HCl‚ we started with buffer 1. The

ACID BASE TITRATION OBJECTIVES 1. To demonstrate the basic laboratory technique of titration 2. To learn to calculate molarity based on titrations INTRODUCTION Molarity (M) or molar concentration is a common unit for expressing the concentration of solutions. It is defined as the number of moles of solute per liter of solution (or millimoles of solute per milliliter of solution). The concentration of a basic solution can be determined by titrating it with a volume of a standard acid solution (of

important in determining whether a reaction will produce a precipitate. Starting out the experiment‚ HCl was added to the solution in the test-tube in order to form a reaction between the HCl‚ Ag‚ Pb‚ and Hg cations. The products of this addition of HCl were PbCl2‚ AgCl‚ and Hg2Cl2. After the HCl was added‚ the solution turned a milky white color. It was important to not add too much HCl because excess HCl would have caused an aqueous complex of PbCl2 and AgCl to form instead of the desired solid PbCl2

Titration Bonnie Abella Dr. Asmita Kane Budruk 2/09/2014 Abstract: the complexometric EDTA titration was used to determine the salt substance in the water. This technique for the unknown sample 154 produced a water hardness of 8.43 x105=mg/L CaCO3 from the collected data which corresponds to the typical value from the city of Tempe. Introduction When the water from the rain collects impurities by dissolving the salt that is exist in the soil. These particular salts
