Abstract: Gravimetric analysis can be used to determine the percentage of phosphorus in plant food. A precipitant of known composition is produced and weighed to find percent of phosphorus in compound. From the mass and known composition of the precipitate, the amount of original ion can be determined.
Introduction: Gravimetric analysis is based on the measurement of mass. Gravimetric analysis involves isolation of an ion in solution by a precipitation reaction, filtering, washing the precipitate …
