To analyse the quality and components of the two different water samples

Extracts from this document...

Introduction

AIM: To analyse the quality and components of the two different water samples provided, using atleast 4 parameters studied before. Parameters selected: (for water analysis) 1)NITRATE CONTENT 2)TOTAL HARDNESS 3)CHLORIDE CONTENT 4)PHOSPHATE CONTENT 5)DISSOLVED OXYGEN CONTENT REQUIREMENTS: * Beakers * Measuring cylinder(25ml , 10ml) * Aquasol kit (nitrate and phosphate content in water samples) * BOD bottle * Conical flask * Glass rod * pipet NITRATE: Hypothesis: The sample 'B' will have more nitrate content than the sample 'A'. Table 1: To find out the nitrate content in water sample 'a' and 'b'. done by using aquasol kit. Trial number Sample 'A' (ppm) Sample 'B' (ppm) 1 0.0 1.0 2 0.0 0.5-1.0 3 0.5 0.5 Table 2: average readings of sample 'A' and 'B' S.R. NO. Average of sample 'A' Average of sample 'B' Average of sample 'A' and 'B' 1 0.16 0.58 0.37 GRAPH :1, showing nitrate content in sample 'A' and 'B' in three trials. PHOSPHATE: Hypothesis: The phosphate content of sample 'B' will be more than sample 'A'. Table :3 to find the phosphate content in water sample 'a' and 'b', using the aquasol kit. Trial number Sample 'A' (ppm) Sample 'B' (ppm) 1 5.0 10.0 2 0.0 5.0 3 5.2 5.0 Table :4 to find the average readings of sample 'a' and sample 'b'. ...read more.

DISSOLVED OXYGEN: (DO) Hypothesis: The dissolved oxygen in sample 'B' will be more than the dissolved oxygen in sample 'A'. Table:11 to find the amount of solution required from the burette by which DO can be found.

Conclusion

This hypothesis of mine was proved correct this can be referred to table number:11 where the amount of solution is used by sample A and B. Table number:12 shows us the average solution used or added to sample A and B. there are two graphs ( 5 and 6) which show the total and average burrette readings for the solution. CONCLUSION: Nitrate content: the nitrate content in the water sample B was more than in water sample A. this thus, proves my hypothesis.( aquasol kit) Phosphate content: the phosphate content in water sample B was more than in water sample A. this too proves my hypothesis correct. The aquasol kit was used for this experiment. Chloride content: the total chloride content in water sample B is more than water sample A.this experiment was conducted by adding CD3 and CD4 drops in the water samples. Total hardness: the total hardness of water sample A was more than water sample B. the total hardness experiment was conducted by adding Th3 and Th4 drops to the water samples by this the number of drops we can use the formula and evaluate the total hardness of the water. Dissolved oxygen(DO) : This experiment was carried out by using the wrinklers method of titration. In this method the amount of solution used from the burrette/pipet was recorded. Thus, by evaluating these readings with the formula given we can find out the dissolved oxygen in the water sample. ?? ?? ?? ?? ...read more.

    However the reaction will stop after a certain temperature as it denatures the enzyme therefore changing the shape of the active site so that the substrate cannot bind to it. This happens due to the enzyme starting to vibrate because of the higher temperature.

    When the nymphs reach their last instar, they crawl out of the water and moult one last time, becoming adults. In most species, the adult stage feeds but dies shortly after mating. Stonefly nymphs play an important role in freshwater systems, serving as a food source for various fish and invertebrate species.
