Question

Which methods is more precise amd accurate ? Gravimetric analysis or Edta titration? Please elaborate

Answer 1

This is a good question. EDTA titration is a more precise and accurate than gravimetric analysis method. in EDTA titration chemicals are used that gives us more accurate result and preciseness.

in Gravimetric analysis is a type of quantitative analysis that depends on weighing. For example, the amount of lead in a solution of lead nitrate could be measured by adding excess hydrochloric acid (this is only one of several reagents that could be used) to precipitate lead chloride, filtering the precipitate, washing, drying, and weighing.

forever in EDTA titration is a type of volumetric analysis in which the volume of one reagent, known as the titrant, is added to a known volume of another reagent slowly from a burette until an 'end point' is reached. The volume added before the end point is reached is noted. This method is used for calculating the concentration of an unknown solution. If one solution has a known concentration, then the other one can be calculated.
