1) Primary standard: primary standard is a highly pure compound which is a reference for identifying the concentration of a known compound in titration.
Titrant: in titration; titrant is a solution whose concentration is known. When there is an unknown solution (analyte), titrant is used for identifying the concentration of that unknown by adding titrant to analyte. (using burette)
Acid –base indicator: acid- base indicator is an indicator that determines the pH of a solution by changing its color due to H+ ion concentrations inside the solution.
Indicator range: acid- base indicators change their colors when pH changes. However, they are useful in a specific pH interval. pH of a solution cannot be determined if pH is out of the interval of …show more content…
Titration curve: titration curve is a curve that shows how the pH changes when the titrant is being added.
Buffer solution: buffer solution is simply a mixture that contains either a weak acid and its conjugate base or a weak base and its conjugate acid. It is used for keeping the pH constant in a solution.
Standardization: If there is an unknown solution, titration which is used for identifying the concentration of a known solution to find out the unknown solution’s concentration is called standardization.
2) Necessaries for a good primary standard are that, it should have a purity at a high level, it should have an atmospheric stability, it should not be hygroscopic in order to reduce the error caused by humidity, it should not be expensive, it should be relatively soluble in titration medium and it should have relatively large molar mass in order to reduce error caused by measuring the …show more content…
Equivalence point is a point where the amount of titrant and the analyte are equal. It means that reaction has finished and adding extra titrant will not make the indicator change its color. Equivalence point in a titration may be more than one. (for example: polyprotic acids and bases)
7) First reason is that, just because titration is a neutralization; strong acids or strong bases are commonly used as titrants. The second reason is that; in order to use a compound as a titrant, the exact concentration of that compound must be known. Since exact concentration of a weak acid is hard to obtain, weak acids are not usually used as titrants.
8) In concentrated solutions; titration curve has an S shape, meaning that a few drops of titrate causes a huge increase in pH and makes it very hard to obtain specific pH areas. In diluted solutions; the part below the equivalence point is smooth, meaning that specific pH areas can be obtained such as buffer zone, which is a mixture of weak acid or base, and its conjugate occurs in
