What is the reason of heating solution during redox titration?
This is far to be a rule for this titration.
Why you are adding marble chips during heating?
Marble chips are added during heating so that the solution or substance can boil evenly. Evenly boiling the solution will cause it not to have heating spots, which can cause an eruption of bubbles. Heating spots are caused when the heat being applied is only getting to the liquid at the bottom of the flask, causing the liquid down there to evaporate more quickly than the upper liquid. The liquid evaporating causes bubbles to shoot through the solution vigorously, disrupting the system. To avoid these heating spots, we add marble chips or boiling chips to induce a nice, even boil.
Why is there no chemical equation to describe what happens when water evaporates?
That's because there is no chemical change. In most cases, there is no chemical change when a substance evaporates. The exception is very long molecules, which may break apart during evaporation.
If the mass of the powder in the evaporating dish increases after heating this indicates that?
the copper must have combined with another substance.
When polystyrene dissolves in acetone what properties does the solution have and what gas is given off?
When polystyrene dissolves in acetone, the solution appears cloudy or milky due to the dispersed polymer chains. During the dissolution process, acetone evaporates, and the gas given off is acetone vapors.
What is the purple substance of the iodine after heating?
It is vapour formed during the process of sublimation.

How can evaporation be used to keep things cool?
Evaporation can be used to keep things cool by absorbing heat from the surroundings during the process. This can be achieved by exposing the object to be cooled to a substance that evaporates easily, such as water or alcohol. As the substance evaporates, it absorbs heat from the object, causing it to cool down.

Was there a new substance formed after heating the iron sulfur mixture?
Yes, a new substance, iron sulfide, was formed after heating the iron-sulfur mixture. Iron sulfide is a chemical compound that results from the combination of iron and sulfur atoms during the heating process.
What happens to the concentration of salt in a salt water solution as it is being boiled?
Salt does not boil away at approx. 100 Celsius. The water evaporates causing the concentration of salt to increase.

Why porcelain piece add in solution during heating?
to not to exceed high tepareture, so that the instrument cannot damage during process
What is titrant and analyte?
Titrant is the solution of known concentration that is added to the analyte during a titration to determine its concentration. The analyte is the substance being analyzed in the solution that reacts with the titrant.
If the mass of the powder in the evaporating dish increases after heating this indicates that?
the copper must have combined with another substance.
What is a titration-quenching?
Titration quenching is a process where a substance is added to a solution to stop a chemical reaction or change in pH during a titration experiment. This substance helps to stabilize the solution at the endpoint of the titration, ensuring accurate results.
What curve shows the relationship between temperature and time?
A temperature vs. time curve is often represented by a heating or cooling curve. During heating, temperature increases over time at a steady rate until reaching a plateau where a substance changes state. During cooling, temperature decreases over time at a steady rate until reaching another plateau at the substance's freezing or melting point.
