Thermometric Titration Investigation

We have to plan an experiment which measures the temperature change accompanying neutralisation so that it can be investigated. Neutralisation is when an acid and an alkali mixed together neutralise the other. The hydrogen and the hydroxide ions bond to form water and the rest bonds to form a salt. For example in the case of hydrochloric acid and sodium hydroxide, the salt is sodium chloride. Neutralisation is an exothermic reaction, like all reactions where bonds are formed. I plan…...

To determine the molarity of a given sample of Sulphuric acid by using titration
Words • 1252
Pages • 5
A volumetric analysis is a method used to find out the amount of solute in a solution. It involves preparation of a primary standard, which is a solution of known molarity, and titration. When choosing a good primary standard, the requirements are that it should be cheap, stable in atmosphere and should not be hygroscopic to prevent the loss of solution. Also, it should have a high purity and high molar mass to prevent serious weighing error. In this experiment,…...

Words • 1136
Pages • 5
In this following experiment, we are aiming to determine the relative atomic mass of magnesium, using a process known as 'back titration'. The basic outlines of this experiment include a strip of magnesium being allowed to reach with excess hydrochloric acid. The excess acid is then determined by titration with a standard alkali (Sodium Hydroxide) and hence the moles of acid that reacted with the magnesium is found by difference. This can be used to determine the number of mole…...

Method for Control of Variables 1. In order to control the titration of potassium permanganate, we used the pipette to make the titration constant. We also used the same amount of chemical solutions, with the same flasks, to make the titration as constant as possible. 2. To control the amount of redox in the experiment, we have used the pipette to keep on putting the same amount of drop every time. The pipette made the amount of redox constant for…...
Determinating the percent acetic acid in vinegar using titration
Words • 722
Pages • 3
Qualitative: As we add sodium hydroxide to vinegar with the phenolphthalein the solution instantly turned pink and then instantly turned colorless.  As we got closer to equating the moles of H+ Ions with OH- the pink would stop turning into colorless leaving a pale pink color. Data processing: Trial 1: In order to determine the mass of the acid, we have to calculate the moles of acetic acid used, and we can get that by multiplying the volume of sodium…...

To get the Ka of acetic acid, HC2H3O2 I will react it with sodium hydroxide. The point when our reaction is half-titrated can be used to determine the pKa. As I have added half as many moles of acetic , as NaOH, Thus, OH- will have reacted with only half of the acetic acid leaving a solution with equal moles of HC2H3O2 and C2H3O2-. Then I will use the Henderson-Hasselblach equation to get pKa. CH3COOH + NaOH H2O + NaCH3COO…...

Introduction According to Arrhenius definition, acid is substance that produces H3O+ ion while base is substance that produces OH- ions. The reaction between acid and base often yields the products of salt and water. The formation of water in this neutralization reaction is caused by the combination of H3O+ and OH- ions. In order to determine the concentration of an unknown acid and base, a method called acid-base titration is used. The end of the titration has been reached when…...

Like any titration, neutralization titrations depend on a chemical reaction between the unknown solution and a standard reagent. The point of chemical equivalence is indicated by a chemical indicator or an instrumental measurement. When the color changes to the specified color, the titration has reached endpoint. The mole ratio and volume relates the concentration of the solutions. The more the number of moles of the base is used the more number of moles are needed to neutralize. To increase the…...

When the end point is reached in an acid-base titration, the relationship between the concentrations of OH- and H3O+ are that they are equal. This doesn’t mean that the pH will be neutral, but the concentrations of both will be the same in a titration. The pH of the end point is determined by what kind of indicator is used to indicate when the end point I reached. In this experiment, phenolphthalein was used. It shows a color change in…...

Abstract: This experiment demonstrated that by titrating barium hydroxide, Ba(OH)2 solution with a sulfuric acid, .1 M H2SO4 solution the point of equivalence can be obtained. Since they were ionic compounds, then the lowest conductivity reading was the point of equivalence because at that reading they were both at a non-ionic state since all their ions have been completely reacted. A first when the H2SO4 was added the conductivity was high, 17.8 umho, then as more H2SO4 was added it…...
