Table: 6 to find the average number of CD3 and CD4 drops added in the solution.
Formula:10*no. of CD3 drops and 50*no. of CD4 drops.
By formula: chloride content in sample ‘A’-560ppm
sample ‘B’- 3700ppm.
Table :7 total amount of chloride present in sample ‘A’ and sample ‘B’.
Graph :3 showing the number of CD3 and 4 drops added in the solution.
TOTAL HARDNESS:
Hypothesis :
In sample ‘a’ there will be total hardness present in the water whereas, in sample ‘b’ there will be very little or no total hardness present.
Table :8 to find the total hardness present in sample ‘a’ and sample ‘b’.
Table:9 average reading of Th3 and 4 drops added in sample ‘a’ and ‘b’.
Formula:CACO3=2*no. of Th3 drops and 5*no. of Th4 drops
By formula: sample‘A’:122*2=244ppm ; sample‘B’: though 185 drops added to the sample no hardness was found.
Table:10 showing total hardness in sample A and B.
Graph:4 showing number of drops of Th3 and 4 added in sample ‘A’ and in sample ‘B’( though total hardness in sample ‘B’ is nil).
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.
Table:12 to know the total and average solution used by sample A and sample B.
Graph:5 this graph shows the total amount of solution used by
sample B and sample A.
Graph:6 this graph shows the total and average solution used in sample A and B:
Table:13 this table gives an overview of all the total or final readings of each and every parameters.
DISCUSSION:
Nitrate content in water:
To find the nitrate content in water, the aquasol kit had to be used. All the directions and methodology had been provided to us.
As my hypothesis shows that sample ‘B’ will have nitrate content than sample ‘A’, this hypothesis of mine was proved to be correct as the nitrate content in B was more than in sample A (refer to table number:1) which proves my hypothesis. By this experiment , I have learnt how to find out the nitrate content in water.
Phosphate content in water:
To find the phosphate content in water, the aquasol kit was used. My hypothesis shows that water sample ‘B’ will contain more phosphate content than water sample ‘A’. This is shown in table number:3. This table proves my hypothesis.
Chloride content in water:
To find the chloride content in water,CD3 and CD4 drops had to be added to the water to find the chloride content in water,in the water sample A CD3 drops had been used where as in sample B CD4 drops were used. 3 trials were carried out for both the sample’s of water the readings of which can be noted by referring to table number:5 and the average drops of each sample can be noted by referring to table number:6. To find the total chloride content in water samples A and B, a formula had to be used which is shown above, the total content of chloride in water sample A and B is shown in table number:7.
Total hardness in water :
To find the total hardness in water ,Th3 and Th4 solutions had to be added to water sample A and B. my hypothesis was proved to be correct, that is sample A will have more hardness than sample B this can be noted by referring to table number:10. The total number of Th3 and 4 drops added to water samples A and B can be noted by referring to table number:8 whereas , the average number of drops added to water samples is shown in table number:9.
DO: (DISSOLVED OXYGEN)
As my hypothesis shows, the dissolved oxygen in sample B will be more than DO content in sample A. 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.
