Question

Section: Post-lab Questions l. Did you observe a difference in conductivity of deionized water and tap water. If yes, ex is a difference. If yes, explain why there was the conductivity of solid sodium chloride?. What was the conductivity of the mixture when water was added to the salt? Explain your observations. 3. Indicate whether solutions of each of the following contain only ions, only molecules, or mostly molecules and a few ions. Type of particles in aqueous solution I. NaCI 2. NaOH 3. C2H OH (Ethanol) 4. HCI 5. CH,COOH (Acetic 6. NH

Explanation / Answer

Q no 1=
Yes, the conductivity of tap water is higher in comparison with deionized water this is because tap water contains ions. The tap water has higher conductivity due to the presence of the ions: Ca2+ and Mg2+.
