Gravimetric Determination of Calcium Essay

Gravimetric Determination of Calcium ABSTRACT Determining the mass of a pure compound is a method of a gravimetric analysis. One of the gravimetric analyses is the precipitation; it is a method of separating the analyte from the unknown sample as a precipitate where it will be filtered and converted into a known composition that can be weighed to determine its mass (Skoog et al, 2013).

Calcium (Ca) is one of the most important nutrients that affect the susceptibility of the plant to disease in two ways. It is important for the cell wall stability, where Ca polygalacturonates were required to strengthen the middle lamella. It is also crucial for the function and stability of plant membranes. Deficiency of this nutrient leads to membrane
