Title: Ms. K Cell Membrane and Homeostasis Experiment Objective(s): The reason for this experiment is to see how starch and iodine affect each other and how a plastic bag works similar to a membrane in certain situations. Introduction: I know prior to doing this experiment that iodine mixed with starch creates a dark color and that most objects‚ organic and inorganic‚ naturally experience isotonic reactions. Hypothesis: I think that the potato will absorb more starch than the sweet potato and

purple. D. What is the purpose of iodine in the Gram’s stain procedure? (What is a mordant?) The iodine helps set the stain by forming an insoluble crystal violet-iodine complex. Basically helps retain the crystal violet to the cell. E. What is the purpose of acetone-alcohol in the Gram’s stain procedure? It is a decolorizer that differentiates between gram-negative and gram-positive. Only the gram-positive bacteria will retain the crystal violet-iodine complex. Gram-negative bacteria will

Oils react with Iodine‚ chlorine in aqueous alcoholic solution to form iodo-chloro derivatives. Terms related Definitions: Iodine value: Iodine value may be defined as the number of gm of Iodine that will add across the Carboncarbon double bond in hundred (100) gm of the fats or oils. Or simply the amount of iodine (in gm) absorbed by 100gm of fat. Significance: Iodine value is a measure of the extent of un saturation in fats or oils. The greater the number of double bond more iodine is required to

drink healthy and clean water‚ many ways of purifying water have been invented. I am going to talk about two of the ways to cleanse water and the limitations of the methods in social and economic perspective. Iodine treatment is one of the easiest and cheapest ways to purify water. Iodine solution has been shown to be effective on killing the microorganisms like Giardia cysts
