What is the chemical reaction between lugols solution and a starch?
Iodine
What is the purpose of adding iodine solution to the onion cell?
to check the approximatedly amount of starch in it since starch in reaction with iodine a black purple colour is formed
Will whole milk expect to react with a color change if mixed with iodine potassium iodide solution?
Any reaction; iodine is used to test the contamination with starch.
HOW DO THE RESULTS OF THE IODINE TEST INDICATED THAT HYDROLYSIS OF STARCH OCCURRED?
An iodine solution turns a purplish-black if it comes into contact with the presence of a starch molecule. This reaction can take place at very minute concentrations of starch.
What is the difference between Iodine bought in a pharmacy and the Iodine stain solution?
The iodine stain solution you're referring to might be Lugol's iodine. This is iodine and potassium iodide in water. The product available in a pharmacy is tincture of iodine which is iodine and potassium iodide in ethanol and water. Please see the links.
What is the reaction between iodine solution and ccl4?

What is the chemical reaction between lugols solution and a starch?
Iodine
What will the result of ethanol plus iodine be?
Diatomic Iodine is non-polar, so the reaction will likely be a solution
Which color is given by glycogen on reaction with iodine?
reddish-brown * the color of glycogen solution with drops of NaCl and Iodine solution is Dark Orange. :) *NaCl will intensify the colour as it fulfills the optimum ionic requirement of the reaction
Why iodine kept in dark during titration?
iodine solution should be kept in dark because it is highly photosensetive.light accelerates a side reaction in which iodide ions are converted to iodine..
What is one of the possible products of a solution if CaI2 is mixed with a solution of NaNO3?
A reaction doesn't exist; the solution contain ions of calcium, iodine, sodium and nitrate.
Why iodine solution stored in coloured bottled?
Iodine solution reacts with light to undergo a photodecomposition reaction and therefore must be stored in amber bottles to minimise the amount of light that the solution is exposed to. If stored in a clear bottle it will gradually break down as the iodide ions are gradually converted to iodine and the solution turns a yellowish colour.
Can iodine solid react with potassium fluoride solution?
Any reaction would be too miniscule to notice.
What is the equation for the displacement reaction between potassium chloride an and iodine solution?
They don't displace each other.
What is the purpose of adding iodine solution to the onion cell?
to check the approximatedly amount of starch in it since starch in reaction with iodine a black purple colour is formed
Will whole milk expect to react with a color change if mixed with iodine potassium iodide solution?
Any reaction; iodine is used to test the contamination with starch.
Is iodine solution ionic?
A solution of iodine is covalent.
