Would a substance with an iodine number of zero be considered saturated or unsaturated?
A substance with an iodine number of zero would be considered saturated because it indicates that all the carbon-carbon bonds are single bonds without any double or triple bonds. Unsaturated substances have double or triple bonds that can react with iodine, yielding a non-zero iodine number.
Could the change in the pH paper itself be a reaction Support your answer?
The substances contained in the pH paper react with the substance to be tested; and this is a chemical reaction.
How does iodine react on starch?
Iodine reacts with starch to form a dark blue or purple complex. This reaction is used as a test to detect the presence of starch in a substance. The blue color is a result of iodine molecules getting trapped within the helical structure of starch molecules.
Do iodine and lithium bromide react?
