When does iodine turn black when rice is added to iodine or iodine is added to rice?
When iodine is added to rice, it turns black when it comes in contact with starch. Starch is present in rice, so when iodine is added to rice, it reacts with the starch and forms a dark blue-black color. This reaction is often used to test for the presence of starch in foods.
What is the color of iodine when mixed in carbon tetrachloride?
depending on the amount of iodine or carbon tetrachloride, it will be eaith pink(more CCl4) or violet (otherwise) please correct me if i'm wrong
Will cooked rice turned dark blue with iodine solution?
No, cooked rice will not turn dark blue with iodine solution. Iodine solution is commonly used to test for the presence of starch in a substance, as it will turn blue-black in the presence of starch. However, rice primarily contains carbohydrates in the form of starch, which is broken down during the cooking process, so there is little to no starch left in cooked rice to react with the iodine solution.
What happens when sugar and iodine is mixed?
When sugar and iodine are mixed, the iodine will turn purple or black due to a reaction with the starch that is naturally present in sugar. This color change is commonly used as a simple test for the presence of starch.
What happens to iodine when you mix it with citric acid?
When iodine is mixed with citric acid, the iodine can be dissolved or react with the citric acid to form iodine citrate. This reaction can alter the properties of iodine, such as its solubility, color, or chemical behavior.
What color is iodine when mixed with dichloromethane?
When iodine is mixed with dichloromethane, the resulting color is purple or violet.
Why does petrol change color when mixed with iodine solution?
Petrol changes color when mixed with iodine solution due to covalent bonding.
What color does cooked rice have when added iodine?
When cooked rice is added to iodine, it typically turns a blue-black color. This reaction occurs because iodine binds to starch present in the rice, forming a complex that exhibits this distinct coloration. The intensity of the color can vary depending on the starch content in the rice.
What happens when Iodine is added to cooked rice?
When iodine is added to cooked rice, a color change will occur if starch is present in the rice. The iodine will turn from yellow-brown to blue-black if starch is detected, indicating the presence of carbohydrates in the rice. This is because iodine interacts with the starch molecules in the rice, causing the color change.
What will happen to boiled rice when you put iodine on it?
The color become blue.

What color does CaSO4 turn into with iodine?
When calcium sulfate (CaSO4) is mixed with iodine, it forms a yellowish-brown color due to the reaction between the calcium sulfate and iodine.
What color is iodine when mixed with decane?
When iodine is mixed with decane, it typically forms a purple or violet color. This color change is due to the reaction between iodine and the carbon-carbon double bonds in decane, resulting in the formation of an adduct that absorbs light in the visible spectrum, giving it a purple color.
Does sugar turn blue when mixed with iodine?
Yes, sugar does not turn blue when mixed with iodine. Iodine reacts with starch, turning it into a blue-black color. Sugar does not contain starch, so it will not have a reaction with iodine in this way.
