Explanation / Answer

0.1 M solution of a strong acid : very low pH and high conductivity

0.1M solution of a weak acid : pH less than 7 and conductivity is low

0.1 M solution of a strong base : very high pH and high conductivity

0.1 M solution of a salt of strong acid and strong base : pH is neutral and conductivity is high

0.1 M solution of a salt of strong acid and weak base : pH less than 7 and conductivity is high

0.1M solution of a weak base : pH greater than 7 and conductivity is low

0.1 M solution of a salt of weak acid and strong base : pH greater than 7 and conductivity is low

deionized water which is boiled and cooled : pH is neutral and conductivity is almost zero
