Would iodine be effective if testing for the presence of lactose?

No, iodine would not be effective for testing the presence of lactose. Iodine is typically used to detect the presence of starch, not lactose. To test for lactose, you would typically use reagents like Benedict's solution or glucose test strips.


Can povidone iodine be used for the patch test instead of tincture of iodine?

Povidone iodine should not be used for patch testing as it contains other additives that may cause irritation or interfere with the test results. Tincture of iodine is a pure form of iodine that is more appropriate for patch testing for potential allergic reactions.


How much iodine does Himalayan salt have?

Himalayan salt contains very small amounts of iodine, significantly less than iodized table salt. It is not a reliable source of iodine and should not be used as the sole source of this essential nutrient in the diet. It is recommended to consume other iodine-rich foods, or use iodized salt for adequate iodine intake.


Do you add iodide when testing for starch?

Yes, iodine is added when testing for starch. Iodine will change color to blue-black in the presence of starch. This color change helps to indicate the presence of starch in the substance being tested.


What is the Conclusion of testing iodine and starch in expariment?

The conclusion of testing iodine and starch in an experiment is typically that a blue-black color change indicates the presence of starch in the solution. This is due to the formation of a complex between iodine and starch molecules. The test can be used as a qualitative test for detecting the presence of starch in a sample.
