What happens when you add iodine with water?
When iodine is added to water, it forms a solution where the iodine molecules dissociate, producing a characteristic brown color. This color is due to the interaction of iodine molecules with water molecules.
How do you extract benzoic acid from chloroform?
To extract benzoic acid from chloroform, first dissolve the benzoic acid in water. Then, add chloroform to the mixture and shake well to allow for the benzoic acid to transfer to the chloroform phase. Finally, separate the two phases and evaporate the chloroform to obtain the benzoic acid.
What happens if you add iodine to flour?
When iodine is added to flour, it forms a complex with the starch molecules in the flour, creating a blue-black color. This reaction is often used as a test to detect the presence of starch in a sample.
Could you determine the density of chloroform using water?
Yes, you can determine the density of chloroform by measuring its mass and volume using water displacement method. You'll need a known volume of water, measure its initial volume in a graduated cylinder, then add chloroform which will displace the water and measure the final volume. By knowing the mass of chloroform and the change in volume of water, you can calculate the density of chloroform.
How do you separate chloroform using the separating funnel?
A separating funnel is especially designed for separating liquids such as chloroform. So long as a person follows the instructions that came with it and does pour the liquid carefully then it will work.
What will happen when you add strong iodine solution to chloroform?
When strong iodine solution is added to chloroform, no immediate reaction will occur. However, if the mixture is exposed to light, chloroform may undergo photochemical decomposition to produce hydrogen chloride gas and elemental iodine. This reaction is not commonly used and caution should be taken due to the toxic nature of the resulting products.
What happens if you forget to add starch before putting the iodine in a beverage?
you will die
What happens if you add iodine 2 potato what do you observe?
The potato will turn blue, purple, or black as the iodine reacts to the starch in the potato.
What happens when you add iodine to water?
Nothing special happens and no reaction occurs. Iodine is hardly soluble in water.
What happens when you add iodine with water?
When iodine is added to water, it forms a solution where the iodine molecules dissociate, producing a characteristic brown color. This color is due to the interaction of iodine molecules with water molecules.
What happens if you add iodine to potato?
If you add iodine to a potato, the iodine will react with the starch present in the potato. This reaction will result in a color change, turning the potato a blue-black color where starch is present. This can be used as a test to detect the presence of starch in foods.
How do you get iodine in foods?
Iodine is found in foods with seaweed. To add iodine to your food, add kelp, wakame, or kombu to the food while cooking.
What happens if you add iodine drops to a non-starch?
If you add iodine drops to a non-starch substance, such as sugar or protein, there will be no color change. Iodine is used to detect the presence of starch by turning blue-black in the presence of starch molecules. Non-starch substances will not produce this color change.
How do you extract benzoic acid from chloroform?

What happens when you add iodine to orange juice?
When iodine is added to orange juice, a chemical reaction occurs between the iodine and the vitamin C present in the orange juice. This reaction causes the iodine to be reduced, changing its color from brown to blue-black. This color change is a result of the iodine molecules accepting electrons from the ascorbic acid (vitamin C) in the orange juice.
What happens if you add iodine to calcium carbonate?
When iodine is added to calcium carbonate, no significant reaction occurs between the two compounds. Iodine does not react with calcium carbonate because the two compounds have different chemical properties.
