POST-QUESTIONS 1. After a student dissolved 0.5 g of white solid in water, she tested the conductivity and determined that the solution did not conduct electricity. The student then concluded: "when the white solid dissolved it 'just disappeared' so some sort of error must have been made because all solids are ionic compounds and, therefore, are electrolytes." Comment on the student's conclusion. Is her statement a valid conclusion? If so, identify what is correct. If not, write a conclusion that would be correct.
