How is residual titration performed? Residual Titrations— Some Pharmacopeial assays require the addition of a measured volume of a volumetric solution,in excess of the amount actually needed to react with the substance being assayed,the excess of this solution then being titrated with a second volu...
Different substances absorb specific wavelengths of light, leaving the complementary colors to be seen. As light passes through a substance of unknown concentration, the amount of light absorbed is proportional to the amount of substance present. So concentration can be calculated by the measured absor...
Plug your values into the Henderson-Hasselbalch equation, pH = pKa + log ([A-]/[HA]), where [A-] is the concentration of conjugate base and [HA] is the concentration of the conjugate acid. Keep in mind that since you've measured pH as a function of the titrant's volume, you need...
Give two reasons why pH 5.5 is used for the Zn-EDTA titration. How does the presence of acid in our stomachs when we drink milk affect our ability to absorb calcium ions in milk? Is the purpose of a buffer system to keep a solution neutral? If not, what is the purpose?
You have a beaker with a measured 10mL of HCl (unknown Molarity) which you weigh the solution as 10g. You need to find out the mass of the solvent. Ultimately, I need to determine the Molarity of the solution but I need themass of solvent(the water in the HCl solution) to determine ...
How is titration used in the dairy industry? How does the needle of a seismograph work? How does a potometer measure the rate of transpiration? Why is absorbance of a bacterial culture an indicator of cell density? How and what is measured to see if photosynthesis is taking place?

Obtaining the chloride ion concentration of sodium chloride with the help of titration accompanied by silver nitrate solution. Know about the entire process in detail.
Titration Equipment To set up a titration, you need an Erlenmeyer flask or beaker, an excess amount of solution of known concentration (titrant), a precisely measured amount of analyte (used to make the solution of unknown concentration), an indicator, a calibrated buret (a glass device that ...
Titration is a quantitative chemical analysis that adds a solution to the sample. The titrant will contain a known chemical that reacts with the substance for which the assay is being done. Gravimetric analysis is the most commonly used wet method. The material is precipitated, filtered, washed...
