The rate of formation of iodine can be calculated by measuring the change in concentration of iodine over time. This can be determined using the equation Rate = Δ[I2]/Δt, where Δ[I2] is the change in concentration of iodine and Δt is the change in time. This rate can be expressed in units such as M/s.

Calculate the initial rate for the formation of rm C at 25 rm circ C if rm A0.50 M and rm B0.075 M?
To calculate the initial rate, you need to know the rate law for the reaction. From there, you can plug in the initial concentrations of A and B to determine the rate constant. Without the rate law, it's not possible to calculate the initial rate.
Iodine turns what colour when its positive for starch?
Iodine turns blue-black when it tests positive for starch due to the formation of a starch-iodine complex.
What happens when you mix citric acid and iodine?
When citric acid and iodine are mixed, they react to form iodine citrate. This reaction results in the formation of a pale yellow precipitate.
What is weight of 2 mole percent of molecular iodine?
The molar mass of iodine is approximately 253.8 g/mol. To calculate the weight of 2 mole percent of iodine, you can first find the weight of 2 moles of iodine, and then calculate 2% of that weight.
What does the iodine turns into when starch is present?
Iodine turns a blue-black color when starch is present. This is due to the formation of a starch-iodine complex, where the iodine molecules interact with the starch molecules causing the color change.
Iodine is required for the formation of the?
Thyroid hormone.

Why is the reaction between iodine and acetone catalysed?
The reaction between iodine and acetone is catalyzed by hydroxide ions present in the reaction mixture. The hydroxide ions help in the deprotonation of acetone, making it more reactive towards iodine. This catalysis increases the rate of reaction and allows for the formation of iodoform.
Iodine turns what colour when its positive for starch?
Iodine turns blue-black when it tests positive for starch due to the formation of a starch-iodine complex.

What color does iodine turn in the presence of startch?
Iodine turns blue-black in the presence of starch due to the formation of a complex between iodine and starch molecules.
What is the formula to calculate the rate of osmosis?
how do you calculate the rate of osmosis
Which white powder turns blue-black in iodine solution?
Starch powder turns blue-black in iodine solution due to the formation of a starch-iodine complex.
How you calculate the Safety Activity Rate?

Why does glycogen gives red colour with iodine?
Glycogen gives a red color with iodine due to the formation of a complex between iodine and the helical structure of glycogen. This complex results in a shift in the absorption spectrum of iodine, leading to the red color observed.
