Why is it necessary to determine accurately the cell constant of the conductance cell before carrying out this experiment?
Determining the cell constant is crucial because it relates the conductance of a solution to the actual concentration of ions present. Without an accurate cell constant, the conductance measurements may not reflect the true concentration of ions in the solution. This could lead to incorrect conclusions and data in the experiment.

Why is it not necessary to dertemine accurately the cell constant of the conductance cell before carrying ou the experiment?
Although determining the cell constant accurately is ideal for precise measurements, it is not always necessary before conducting the experiment. As long as the conductance cell is properly calibrated, any variations in the cell constant can be accounted for in the calculations. The key is consistency in the calibration process to ensure reliable and reproducible results.
How does the concentration of electrolytes affect the conductivity of a solute?
The conductance of a given conductor, C = La/l ..(i)\ L = l/Ra ..(ii)The resistance is expressed in units of ohm, the conductance has units of ohm-1 or mho.The conductance of solutions is also governed by the same relations. From (i), if l = 1,a = 1, the specific conductance L = C. That is,the specific conductance (L) is the conductance of the solution enclosed between two electrodes of 1 sq. cm area and 1 cm apart. when you dilute the solution the concentration decrease and the specific conductance also decreaseThe conductance of a solution depends upon the number of ions present and hence on the concentration. To compare the conductivity of different solutions, it is necessary to take the concentration of the solutions into consideration. It is done by using equivalentconductance, l.
Why standardization of EDTA solution is necessary?
Standardization of EDTA solution is necessary to accurately determine its concentration, which ensures precise and consistent results in complexometric titrations. It allows for the calculation of the exact amount of analyte present in a sample. This process is essential in analytical chemistry to minimize errors and ensure the reliability of experimental data.
Why is it necessary to weigh the iron fillings accurately though the mass of copper sulfate taken was only approximate?
This is necessary in analytical chemistry, to obtain correct results.
Why is it necessary to use laboratory apparatuses in conducting an experiment?
Some experiments aren't possible without proper equipment. It is safer to use and accurate values can be calculated in laboratory activity. It is best to use aseptic techniques, so not to contaminate, by lighting a fire.

What are necessary precautions for safety purposes while conducting an experiment?
The necessary safety precautions when conducting an experiment depend on what is done during the experiment and where it is done.

When blood type is necessary when treating pregnant women and surgical patients, how long does it take to determine the type?
In a medical situation, technicians can determine your blood type in two minutes or less to accurately determine your ABO/Rh type crossmatch in order to give you the appropriate blood type.
Why was it necessary to degas the sodas prior to the experiment?
It was necessary to degas the sodas prior to the experiment to remove any dissolved gases, such as carbon dioxide, in order to prevent interference with the results of the experiment. Presence of dissolved gases can affect the accuracy of the measurements taken during the experiment.

Draw a valid conclusion for that experiment.
Is it necessary for a signature to be legible?
Yes, it is necessary for a signature to be legible in order to accurately identify the person who signed the document.
Why is it necessary to determine baseline for H2O2?
It is necessary to determine the baseline for H2O2 to establish a reference point for comparison in experiments. The baseline helps to identify any changes in the concentration or activity of H2O2 throughout the course of the experiment. This allows for more accurate and meaningful analysis of the data collected.
