According to (Green & Bowie‚ 2005‚p.10) In 1990‚ the Patient Self – Determination Act was implemented. This required consumers to be provided with informed consent‚ information about their right to make advance health care decisions (called advance directives)‚ and information about state laws that impact legal choices in making health care decisions.

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 free of contaminants‚ conversion of the precipitate to a product of known composition‚ and finally weighing
