Why you acidify the mixture before recrystallization?
Acidifying the mixture before recrystallization helps in converting any impurities that may be present in the mixture into their respective acid forms, which are typically more soluble in water. This makes it easier to remove the impurities during the recrystallization process, resulting in a purer final product.
Why light reaction first before dark reaction?
There must be a light reaction first before dark reaction. This is so that there is something to be compared.
Is Pancake batter before it's cooked a mixture or substance?
Mixture !!!
A solution in crystallizing rate of the solute equals the dissolving rate of the solute must be?
Maintain a constant temperature during the crystallization process, ensure that the solute is completely dissolved before beginning the crystallization, and provide a suitable environment for crystal formation such as a clean container with no impurities.
Do the compounds remain the same as before the reaction when a chemical reaction occurs?
true

How do the properties of the parts of a mixture compared to the properties of the parts before they become A mixture?
Because there is no chemical reaction, the properties of the elements and compounds do not change when they form a mixture.
Is SO4 a spectator ion?
Sulfate ion (SO4) is commonly considered a spectator ion in many chemical reactions because it remains unchanged and does not actively participate in the reaction. This means it is present in the reaction mixture both before and after the reaction occurs.
What happens before during and after reflux while preparing ester of isoamyl acetate?
Before refluxing, reagents such as isoamyl alcohol and acetic acid are mixed in a reaction flask. During reflux, the reaction mixture is heated under reflux conditions to allow the esterification reaction to occur. After reflux, the reaction mixture is cooled and the ester product, isoamyl acetate, is isolated using techniques such as extraction or distillation.
Why is nitric acid added before silver nitrate to test for bromine?
Nitric acid is added before silver nitrate in the bromine test to oxidize any interfering substances that could react with silver nitrate. This helps to prevent false positive results and ensures that the precipitation reaction with silver nitrate is due to the presence of bromide ions.
What does it mean chocolate seizes?
Chocolate seizes when it hardens and forms stiff crystallization before it is supposed to.
How do the properties of the parts of a mixture compare to the properties of the parts before they become a mixture?
The properties of the parts of a mixture remain the same before and after they become a mixture. Each component retains its individual characteristics such as melting point, boiling point, density, and chemical reactivity. Mixing simply combines the individual properties without altering them.
Is A before blending cake ingredients a solution or a mixture?
It is a mixture
Is pancake batter before its cooked a mixture or a substance?
Mixture !!!

Why reaction mixture added into ice cold water before titration in experiment of kinetics of ester hydrolysis?
Adding the reaction mixture into ice-cold water helps to quench the reaction and halt any further ester hydrolysis. This is important to obtain an accurate measurement during titration, as it ensures that the reaction has stopped and the initial conditions are preserved for analysis. Rapid cooling also helps to minimize the impact of any side reactions that may occur due to heat generated during the process.
