Answer 1

Here are the answers to your questions based on general chemistry principles:

Question 1 The conductivity meter conducts electricity when placed in water.
Response: True

Question 2 There is evidence that NaCl is an ionic substance.
Response: True

Question 3 Adding more NaCl to the solution increases the number of ions in the solution.
Response: True

Question 4 What is the visible evidence that sugar is not an ionic substance?
Response: The conductivity meter does not light up

Question 5 The properties of sugar in this experiment demonstrate it is most likely a/an:
Response: substance that does not conduct electricity
