To find the purity of zinc oxide by titration method, you can first dissolve the zinc oxide in an acid solution to form a soluble zinc salt. Then, titrate the solution with a standardized solution of a known concentration, such as an acid or base, until a color change indicating the end point is reached. By knowing the volume and concentration of the titrant used, you can calculate the purity of the zinc oxide based on the stoichiometry of the reaction.

What is double titration?
Double titration is a titration method used to determine the concentration of a solution by performing two successive titrations. In the first titration, a known concentration of a standard solution is used to titrate the unknown solution. In the second titration, a different standard solution is titrated with the excess volume from the first titration to determine its concentration.
How do you find purity of Ferric and non Ferric alum?
The purity of Ferric and Non-Ferric alum can be determined by conducting a chemical analysis to measure the percentage of the specific compound in the sample. This can be done using techniques such as titration, spectroscopy, or chromatography to quantitatively determine the purity of the sample. It is important to compare the results obtained from the analysis with the known standards to assess the purity accurately.
How do you find concentration of an acid from a titration?
To find the concentration of an acid from a titration, you would use the stoichiometry of the reaction to determine the moles of acid that reacted with the known concentration of base. Then, you would use this information to calculate the concentration of the acid by dividing the moles of acid by the volume of the acid used in the titration.
Why is titration repeated without indicator?
In a titration the pipette is used to transfer 25 cm3 (usually to ±0.05 cm3) of a solution into a conical flask. Another solution that reacts with the solution in the conical flask is carefully added from a burette until it has all exactly reacted. This is called the end point of the titration (or equivalence point of the reaction). There needs to be a way of knowing when the end point is reached. An indicator may be needed. Often a titration is repeated until successive titres are within 0.1 cm3.
What is back titration and how does it work?
A back titration is similar to a direct titration, but a bit more difficult. When an end point is not easily identified due to no colour change, an excess volume of a reactant of KNOWN CONCENTRATION is added to the reactant of unknown concentration. Then the resulting mixture is titrated again (or titrated back) to find the volume of the unreacted reactant, which will tell us the amount that DID react with the solution of unknown concentration. You need to take into account the amount of excess reactant originally added. The relevant calculations can then be taken out. Hence there are three reactants namely A,B,C. Such that it is to find the purity of C. This titration is possible only if A and B can react with each other and A and C can react with each other but the product of A and C do not react with B.

How do you check the alcohol percentage in wine?
Using a method called back-titration, the alcohol concentration of a grape wine can be determined. Just google steps and procedure of back-titration and find out what standard solution and indicator you will need. :)
What is the difference between the endpoint method and the kinetic reaction method?
The endpoint method is used in titration to find the exact point at which the reaction is complete, often indicated by a color change. The kinetic reaction method involves monitoring the rate of reaction to determine the endpoint based on changes in the reaction rate. Both methods are used to quantify the concentration of a substance in a sample.
How get the accutare titration value?
Titration value describes how accurately a substance is dissolved in another substance. In order to find this number, you need a pipette, a burette, and a volumetric flask.
How do you find concentration of an acid from a titration?

Then, you would use this information to calculate the concentration of the acid by dividing the moles of acid by the volume of the acid used in the titration.
How do you find the molar mass of beryllium oxide?
To find the molar mass of beryllium oxide (BeO), you will need to determine the individual molar masses of beryllium (Be) and oxygen (O) from the periodic table and then add them together. The molar mass of Be is about 9 g/mol and the molar mass of O is about 16 g/mol. When you add them together, you'll find that the molar mass of BeO is approximately 25 g/mol.

How do you calculate the moles of H2SO4 in a titration?
To calculate the moles of H2SO4 in a titration, you can use the formula: moles Molarity x Volume. First, determine the molarity of the H2SO4 solution. Then, measure the volume of the solution used in the titration. Multiply the molarity by the volume to find the moles of H2SO4.
What experiments show that sulfuric acid is dibasic?
Titration...after neutralizations with a base, molarity calculations are done and you will find that one mole sulphuric acid needed 2 moles of the given base in order for a complete reaction to occur. Can anyone give the method and calculations to this titration experiment please? and can anyone give a method and calculations to a gas collection experiment to prove that sulphuric acid is dibasic? ... I personally reckon that this is your AS chemistry planning exercise lol Do it yourself!!! make me. how would you know anyway?
