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 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.
When an experiment is performed what are necessary parts to have an accurate study completed?
independent variable dependant variable constants
Why are models necessary in science?
so you can see a visual of the experiment your trying to figure out, but it's not going to be that precise (:
Why was it necessary to balance the frictional force acting on the system with a slight tilting of the track?
To simplify the experiment and the results

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.
Why is an experiment necessary?
An experiment gives us proof that we are right.

The analysis of a data gathered during a particular experiment is necessary in order to?
Draw a valid conclusion for that experiment.
Which condition is necessary for an experiment to yield useful data?
similar results should be obtained when the experiment is repeated .
Why is a skilled labor necessary for a business?
it is necessary because, it is use to show that the business will function accurately with highly educated persons
Why is control setup necessary in an experiment?
Without controlled setup in an experiment. How can the researcher know his data is comparable for study?
Why is necessary to use measuring tools in measuring length of an object?
It is necessary because measuring tools help you measure the length of an object accurately.
Why is it necessary to warm a reaction mixture in stoichiometry experiment?
to fast the reaction
Is it necessary to subtract the water vapor pressure of water in the butane experiment?
yes it is necessary to subtract the water pressure
Why is a control set in a experiment so important?
When performing an experiment it is very important to have a control set. It is important to have a control set because it ensures that the experiment can be repeated as many times as necessary.
