Answer:
Results from method B is more reliable than method A.
Explanation:
The two method that are used for the analysis produced different results. The first method that is method A gives higher value of the iodine content than the method B.
When was added to water, method A showed an increased in the iodine content and it increases with the increase in the amount of
.
Where as in the method B, there is no change in the results. Therefore the measurements provided by the method A shows an inference of ion.
The measurement of the iodine content is affected by the presence of the ion in water.
Since in method B there is no change in measurement, it is independent of the presence ion in water.
As higher iodine content is given by method A, so ion must be present in original water that must be interfering the measurement. Hence, method B is more reliable.
