Study Set Content:
- a special form of a glass vessel rendered
airtight by means of ground contact surfaces,
used to maintain a dry atmosphere for objects
that might be affected by moisture or carbon dioxide.
Dessicators
- can be prepared by dissolving 200g of sodium dichromate in 100ml of water and then adding 1,500 ml of sulfuric acid with slowly stirring.
Cleaning Solutions
the chemical substance being analyzed
Analyte/Active Constituent/ Titrate/ Titrand
- a solution of known concentration used in titrimetric analysis.
Titrant
a process of adding and measuring a volume of titrant used in the assay by means of a burette.
Titration
a chemical which changes color at or very near the point in the titration where equivalent quantities of the analyte and titrant have reacted
Indicator
- a theoretical point at which equivalent amount of analyte and titrant have reacted.
Stoichiometric Point or Equivalent Point
- a point in which there is occurrence of sudden change in property of the reaction mixture/solution, a change made apparent by an indicator.\
End Point or Visual Point
- the direct or residual titrimetric analysis of an acid using accurately measured volume of a base.
Acidimetry
the direct or residual titrimetric analysis of a base using accurately measured volume of an acid.
alkalimetry
- are complex compounds used:
Indicators
Indicators purpose
- to determine the end points in the neutralization process
- to determine Hydrogen-ion concentration [H] or [pH]
