ACKNOWLEDGEMENTS
I am sincerely grateful to my chemistry teacher Mrs. Betty George and lab assistant Mr. Ajay for assisting me in this project.
INTRODUCTION
A chemical fertilizer is a substance applied to different soils or directly onto plants to provide nutrients optimal for their growth and development. The essential nutrients contained in these fertilizers are nitrogen, phosphorous, and potassium (NPK), as well as other nutritional substances in smaller amounts all presented in a form that can easily be absorbed and metabolized by plants. Chemical fertilizers have become a staple in many yards and gardens, and can be a key component of a healthy lawn care routine.
Analysis of fertilizers refers to have a qualitative analysis of each fertilizer so as to find out the cations and anions present in it.
It also includes to find the acidity and basicity of the fertilizer with the help of pHsolution.
Morever I would also find out the solubility of the fertilizer in universal and organic solvent.
To end the analysis I would furthermore test the presence of biuret which is toxic for plants and thus impairs plant growth.
PRINCIPLE
Qualitative analysis means to analyse cations and anions and other elements present in the given samples. The physical and chemical `properties will be observed for the different samples.Principles behind the qualitative analysis are the le chatelier’s principle and the common ion effect.
Le chatelier’s principle states that if a system in equilibrium is subjected to a change of concentration, temperature or pressure, the equilibrium shifts in a direction that tends to undo the effect of change imposed.
If to an ionic equilibrium, a salt containing a
