Abstract: The study was designed to test students attitude towards the three categories of questions in WAEC practical chemistry examination. A survey research design was adopted were a questionnaire was administered to the target population. ANOVA one-way analysis of variance was used to analyse the data collected. It was found that; there is a significant difference in the student's attitude towards the three categories of questions in WAEC practical chemistry examination. Sheffes' test was administered to determine where the differences in attitude lie. It was found that; students have positive attitude towards theory of practicals followed by qualitative analysis, quantitative analysis was the least. Recommendations were made amongst which include: Students should be motivated and encourage in the area of quantitative and qualitative analysis.

Abstract: A simple, quick and convenient method has been developed for the micro estimation of Scontaining amino acids. The sample 1-5 mg is allowed to react with 2 ml of 0.3N ammonium metavanadate (v) reagent and 10 ml of 10N H2SO4 was added, before the reaction helps in detecting the end point. The unconsumed reagent can be accurately titrate with 0.025 N ferrous ammonium sulphate solution using N-phenyl anthranilic acid as indicator. Standard deviation as well as coefficient of variation was calculated for reproducible and accurate result. The accuracy of the method in within + 1%.

Abstract: The present research study has been conducted in the vicinity of industrial city, Kota in Rajasthan where six agriculture fields ,two each of paddy, soyabean and wheat crops were selected for analysis work.. Chemical fertilizers applied in these fields were mainly urea, diammonium phosphate, zinc sulphate and potassium chloride. Soil samples have been collected from every field at various depths prior to and after the crop as well as during the crop growth pH, E.Ce. and water soluble Nitrate (NO3 -), Chloride (Cl-), Sulphate (SO4 2-) and Phosphate (PO4 3-) were estimated in all collected samples. An effort has been made to find the change in soil characteristic of the field before and after the crop.
