Experiment 10: Gravimetric Determination of Calcium as CaC ...

Separating a liquid from a solid involves the commonplace technique of filtration. Thus, the conversion of an analyte dissolved in solution to a solid is often the first step in analyzing it. Calcium ion can be analyzed by precipitation with oxalate in basic solution to form CaC2O4·H2O: Ca2+ (aq) + C 2O4 2-(aq) + H 2O (l) → CaC2O4·H2O (s)

Gravimetric analysis - Wikipedia

Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the …

Gravity separation - Wikipedia

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
