To test for the presence of barium in an aqueous solution, you can add a sulfate solution, such as barium sulfate, which will form a white precipitate if barium is present. For iodine, you can add a few drops of starch solution; if iodine is present, it will produce a blue-black color due to the formation of the iodine-starch complex. Both tests should be conducted under controlled conditions to ensure accurate results.
What else can I help you with?
Why does on aqueous solution of iodine will not react with an aqueous solution of potassium bromide.?
An aqueous solution of iodine (I₂) will not react with an aqueous solution of potassium bromide (KBr) because iodine is less reactive than bromine in terms of oxidation potential. In this case, iodine cannot oxidize bromide ions (Br⁻) to bromine (Br₂), as bromide is a stronger reducing agent. Therefore, no reaction occurs between the two solutions.
What is the name of starch indicators solution?
It is the Iodine dissolved in aqueous Potassium(or Sodium) Iodide
What stain is used to test for plant starch in cells?
aqueous iodine in the form of potassium iodide turns purple in the presence of starches in water.
What is the chermical you test for starch?
Iodine solution is commonly used to test for the presence of starch. When iodine solution is added to a substance containing starch, the mixture turns blue-black in color, indicating the presence of starch.
A chemical solution used to test starch is?
the answer to tis would be iodine because it is uses in the method to test for presence of startch in a leaf
Does aqueous contain iodine or benzoin?
Aqueous solution typically refers to a solution where a substance is dissolved in water. Iodine can be dissolved in water to form an aqueous solution, known as iodine solution. Benzoin, on the other hand, is not typically soluble in water, so it is less common to find it in an aqueous solution.

What is the pH of iodine?
Iodine does not have a pH since it is not an aqueous solution. pH is a measure of the concentration of hydrogen ions in a solution.
What indicator substance is used to test a leaf for starch?
Iodine Solution is used to determine whether starch is present.
Why does an aqueous solution of iodine not react with potassium chloride?
Iodine is not reactive with potassium chloride in an aqueous solution because iodine is less reactive than chlorine. Chlorine is more likely to react with potassium to form potassium chloride, leaving the iodine unreacted.
What happens when you evaporate an aqueous iodine solution?
When you evaporate an aqueous iodine solution, the water will gradually evaporate and the iodine will be left behind as solid crystals. Iodine is not soluble in water, so it will separate out as it becomes less diluted with the evaporation of water.
When lead nitrate solution is added to sodium iodine solution solid lead iodide is formed word equation?
Aqueous lead nitrate plus aqueous sodium iodide produce solid lead iodide and aqueous sodium nitrate.
What is the procedure for the preparation of aqueous iodine solution?
To prepare an aqueous iodine solution, first dissolve iodine crystals in water until the desired concentration is reached. Iodine is sparingly soluble in water, so it may take some time and stirring for complete dissolution. Always handle iodine with care and ensure proper ventilation when working with it.
What is the name of starch indicators solution?
It is the Iodine dissolved in aqueous Potassium(or Sodium) Iodide
What substance does iodine solution test for?
Iodine solution tests for the presence of starch. It turns from brown to blue-black in the presence of starch.
What is the chemical used to test for the presence of starch?
The chemical used to test for the presence of starch is iodine.
Which indicator would you use to test starches?
