Is iodine and water heterogeneous mixture?
Iodine is much more soluble in ethanol than in water, so it will usually form a homogeneous mixture. Of course, if you add more solid iodine than will dissolve in your quantity of ethanol at the temperature at which you are working, the excess solid will sink to the bottom. In that case, you have a heterogeneous mixture.
Why methanol is added to ethanol?
To avoid misuse of ethanol for drinking purpose it is denatured with methanol.
What are the solvent and solute in a containing 100g of ethanol and 3g of sucrose?
solvent=ethanol solute=sucrose because sucrose is added to ethanol.
Is Ethanol an ingredient in Tide?
Yes, Ethanol is in Tide. Ethanol helps keep the other ingredients suspended in the solution. Read more at the related link.
Is water and ethanol a ideal solution?
No this is not an ideal solution, because water and alcohol (ethanol) molecules interact rather complex resulting in eg. an azeotropic boiling point at 96% mixture
Is salt and ethanol a heterogenous solution before mixing?
Almost no salt will dissolve in pure ethanol. If salt is added to a solution of ethanol and water, which are miscible, it may form a homogenous solution without being stirred.
What must be added to an aqueous solution of glucose to convert it into ethanol?
yeast
Why does the color of potassium permanganate not disappear when excess of ethanol is added to it?
KMnO4 is pink in a solution without oxidizing reagents. Adding ethanol should change it to a brown solution. If adding ethanol can not change the solution to brown, then its environment is already acidic and will not reduce.
Is the mixture of ethanol in water a heterogeneous or homogeneous mixture?
The mixture water-ethanol is homogeneous.
What solution is sucrose in ethanol?
This is a homogeneous solution.
What happen when ethanol is heated with alkaline kmno4 solution?
When ethanol is added to alkaline KMno4 solution, the ethanol gets oxidised to ethanoic acid due to nascent oxygen. KMno4 is an oxidising agent. thus when we first add alkaline Kmno4 to ethanol, the pink colour of the Kmno4 vanishes, as it is being used up for the oxidation process. however. when all of the ethanol has been oxidised into ethanoic acid, and we keep adding Kmno4, the colour returns, as there is no more ethanol left to oxidise.
What happens when ethanol is added to soap?
From the experiment, why is a mixture of ethanol and water instead of simply water itself used for saponification? ... Ethanol is the catalyst in saponification C. Ethanol would help the soaps obtained from saponification reaction become more soluble in water D.
A solution is 10 percent ethanol if you have 6L of solution how much ethanol is is the solution?
10% of 6L is 600 ml. 6000 / 100 * 10 = 600 ml.
Why does DNA appear as stringy threads when ethanol is added?
The the nitrogenous bases of the DNA double helix are held together by hydrogen bonding. When a polar, protic organic solvent such as ethanol is added to solution, the H-bonding of the bases pairs break and reform with the ethanol in certain areas. The "stringy threads" that you are seeing are most likely single stranded DNA.
Is iodine and water heterogeneous mixture?
Iodine is much more soluble in ethanol than in water, so it will usually form a homogeneous mixture. Of course, if you add more solid iodine than will dissolve in your quantity of ethanol at the temperature at which you are working, the excess solid will sink to the bottom.

How many distilled water will be added to prepare 1000 ml 95 percent ethanol from 1000 ml 99 percent ethanol?
1. Extract 959,6 mL from the 99 % solution. 2. Add 40,4 mL water.
When calcium acetate react with ethanol calciumacetate absorb ethanol how?
I think what happens is a simple precipitation. Calcium acetate isn't soluble in ethanol, and hence crashes out of solution when ethanol is added to a saturated solution of calcium acetate.The precipitation is quick, leading to small strands of solid Ca(OAc)2, forming a solid gel. A gel consists of a continuous open network and a solvent. The network can be either solid or soluble in the solvent.
