Why the starch solution should be added after the reaction mixture becomes pale yellow and 65311?
The starch solution should be added after the reaction mixture becomes pale yellow because it serves as an indicator for the presence of iodine, which forms a dark blue complex with starch. If added too early, the starch may interfere with the reaction or give misleading results. Waiting until the mixture is pale yellow ensures that the reaction is sufficiently progressed to accurately determine the endpoint of the reaction. This timing allows for precise observations and measurements in experiments involving iodine.

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.
Is Seltzer in water a heterogeneous mixture or homogeneous mixture?
In order for a liquid to be a solution all ingredients must be mixed thoroughly. Since it is impossible to equally diffuse Carbon Dioxide (the carbination) throughout the liquid - Soda Pop would be considered a mixture. If the carbonation were to be entirely removed - the remaining fluid - would be considered a solution.
What is a solution?
A liquid with something dissolved in it
What is the definition of a solute?
Don't really know.....you should ask someone
What is would make a solution?
A solution is typically defined as a homogeneous mixture composed of two or more substances, where one substance (the solute) is dissolved in another (the solvent). For a solution to be effective, it must achieve the desired concentration, stability, and compatibility of components. Additionally, the solution should meet the specific requirements of its intended application, whether in chemistry, pharmaceuticals, or everyday use.
Steam is a solution of liquid and gas so as solution is homogenous mixture so steam should also be homogenous mixture not a compound?
yes it is an homogeneous mixture because it has only one phase
What is a reaction called when it goes red?
A red colored reaction can mean the reaction is serious. When your skin becomes dark red you should seek medical help.
Is milk a mechanical mixture or a solution?
i dont really know but you should try to look it up on google

What happens when you add an alkali to an alkali?
A chemical reaction. Acid + alkali = salt + water eg H2SO4 + 2NaOH = Na2SO4 + 2H2O Sulfuric acid + Sodium Hydroxide = Sodium Sulfate + water Whan as acid meets an alkali they create a chemical reaction. If there is an acid and you add a weak alkali you should bring it down to neutral.
What type of mixture is silver nitrate in water?
silver nitrate dissolves in water. so it should form a homogeneous solution
Mixture in which a substance dissolves into another substance?
A solution is a mixture in which a substance dissolves into another substance at the molecular level. The substance that dissolves is called the solute, while the substance it dissolves into is called the solvent. The result is a homogenous mixture with uniform composition throughout.
Is a mixture of glycerin and potassium permanganate flammable?
A mixture of glycerin and potassium permanganate can be flammable. When glycerin comes in contact with potassium permanganate, a vigorous exothermic reaction can occur, producing intense heat and potentially igniting the surrounding materials. Extreme caution should be exercised when handling this mixture.

What is an incorrect description Question options A homogeneous mixture A heterogeneous compound A solid element A mixture of solids A solution of gases?
A solution of gases is not correct. it should be a mixture of gases
Is rum and Coke a homogeneous mixture?
Since rum is alcoholic, solution should be homogeneous.
Which solutions can be mixed with the pH value 2to yield a neutral mixture?
You can mix a basic solution with a pH higher than 7 with a pH 2 solution to yield a neutral mixture. The basic solution should be strong enough to neutralize the acidity of the pH 2 solution. Common bases like sodium hydroxide or potassium hydroxide can be used for this purpose.
