167 PRELAB This prelab must be completed and handed in to your TA before you start the prelab lecture. Also complete a copy of this prelab so you will have a copy of your predictions as you perform the lab. Prel lab: What do you expect is the effect of concentration? Do you expect the conductivity to a) b) c) What is your reasoning? Go up with increasing concentration Go down with increasing concentration Stay the same even if concentration is increased. What do you expect is the effect of temperature on conductivity? Do you expect the conductivity to: a) Go up with increasing temperature b) Go down with increasing temperature c) Stay the same even if temperature is increased What is your reasoning? What do you expect is the effect of charge on conductivity? In going from NaCiO, to Mgso what are the charges on the ions? Do you expect the conductivity to: a) Go up with increasing charge b) Go down with increasing charge c) Stay the same even if charge is increased What is your reasoning?

Explanation / Answer

when the number of ions increases in the concentartion.As number of ions increases the conductivity increases as there are more number of ions to conduct electricity. A) therefore conductivity increases with increase in concentration.
