Which analytical method is based on the weight of ppt?
Acid base titration
Complexometric titration
Precipitation titration
Gravimetry
Option 1) An acid base titrarion is a method of quantitative analysis for determining the concentration of an acid or base by exactly neutralizing it with a standard solution of a base or acid having known concentration.
Option 2) Complexometric titration or chelatometry is a type of volumetric analysis wherein the coloured compound complex is used to determine the end point of titration.
Option 3) Precipitation titration is a type of titration which involves the formation of precipitate during the titration technique.
Option 4) Gravimetric analysis is a method in analytical chemistry to determine the quantity of an analyte based on the mass of solid.
Therefore,The correct answer is Gravimetry
