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.
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.
the cells are dead so the potato whould not perform any movement
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).
Boiling salt and water together forms a homogeneous mixture called a solution. As the water evaporates, salt crystals will begin to form.
Tomatoes will loss weight in due time when sugar concentration is high enough to exceed the osmotic value of solutes in tomato.
It evaporates.
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.
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.
