A solution is typically boiled just before reaching the second equivalence point to ensure that any remaining reactants are fully reacted and to eliminate excess solvent, which can influence the concentration of the reactants. Boiling helps in ensuring complete dissolution and reaction, thereby providing more accurate results in titration or chemical analysis. Additionally, this practice can help drive the reaction to completion and minimize any side reactions that may occur at higher concentrations.

How will you test for starch in a leaf and mention the precaution you will take?
To test for starch in a leaf, you can use iodine solution. The leaf needs to be boiled in alcohol to remove chlorophyll and then rinsed with water before adding iodine solution. Precaution: Alcohol is flammable, so ensure proper ventilation and avoid direct contact with open flames.
What happens when carrot is boiled and then placed in concentrated salt solution?
the cells are dead so the potato whould not perform any movement
What would be the result of Benedict's solution on boiled amylase?
Because amylase, being an enzyme, is a protein, these molecules will not give a positive result in testing with Benedict's solution. This reagent is devised for testing sugar solutions (like sucrose), which MAY be formed at the amylolytic breakdown of starch (amylose, amylopectin). This breakdown can NOT occur when boiled enzym molecules are used (because of inactivation by denaturation of the protein structures).
What happens to the weight of the tomato when boiled in a sugar solution?
Tomatoes will loss weight in due time when sugar concentration is high enough to exceed the osmotic value of solutes in tomato.
What type of mixture when you boiled salt and water?
Boiling salt and water together forms a homogeneous mixture called a solution. As the water evaporates, salt crystals will begin to form.
What happens to a sugar solution when boiled?
It evaporates.
Why is the glucose solution boiled first before adding the yeast suspension?
Boiling the glucose solution helps to sterilize it by killing any unwanted bacteria or other microorganisms that may be present. This ensures that only the yeast cells are introduced into the solution, creating a clean environment for fermentation to occur.
Why the solution is boiled before titration?
Boiling the solution before titration helps to remove any dissolved gases that may interfere with the titration process. Additionally, heating the solution can help to dissolve the solute more effectively and improve the accuracy of the titration results.
How long are unpeeled boiled eggs good for before they spoil?
Unpeeled boiled eggs are good for about one week in the refrigerator before they spoil.
How long can you refrigerate a boiled egg before it goes bad?
A boiled egg can be refrigerated for up to one week before it goes bad.
How long can you refrigerate hard boiled eggs before they spoil?
Hard boiled eggs can be refrigerated for up to one week before they spoil.
Why is the solution boiled after adding excess hydrochloric acid to the solid hydrate?
to remove carbondioxide from the solution and also to increase the rate of reaction
How long will a boiled egg last in the refrigerator before it goes bad?
A boiled egg can last for about one week in the refrigerator before it goes bad.
