I would like to express my special thanks of gratitude to my teacher (Name of the teacher) as well as our principal (Name of the principal) who gave me the golden opportunity to do this wonderful project on the topic (Write the topic name), which also helped me in doing a lot of Research and i came to know aout so many new things I am really thankful to them! "econdly i would also like to thank my parents and friends who helped me a lot in finali#ing this project within the limited time frame!

TABLE OF CONTENT
ABSTRACT *+R$+"- are sustances which allow the passage of electricity through through their molten state or their a.ueous solution and allow the chemical decomposition at the same time e!g!-acids, ases and salts! *+R$+I* *N/0*+IN- there is flow of electric current through the electrolytes with the motion of ions which are formed due to the dissociation of some molecules of the electrolyte! '12" %W- it states that under constant physical conditions such as temperature, pressure etc!the current flowing through the conductor is directly proportional to the potential difference across the two ends of the conductor! 1athematically, 34IR Where, 34potential difference across the ends of the conductor, I4electric current through the conductor and, R4resistance offered to the path of the electric current y the conductor!
+'R$ 0sing the appropriate electrolyte and keeping the the other factor constant ,the concentration of a particular electrolyte(*u"o) was varied y intervals of 56!Readings of resistances corresponding to different concentrations ranging from 5-576 were taken!
xpected result-the resistance of the electrolyte solution is expected to decrease with increase in concentration!
With increase in concentration, the numer of ions due to to dissociation of electrolyte increases! "ince the rate of charge is directly proportional to the numer of ions, hence conductivity of the electrolyte increases and the resistance of the electrolyte decreases!
