Please answer question 1 and 2
![Part B:
Properties such as melting point, boiling point, solubility, electrical conductivity, and colour, can help
you distinguish ionic from covalent compounds. As in many areas of chemistry, the distinctions are not
always clear, nor do the distinctions apply to all compounds.
The salt and sugar on your kitchen table both dissolve easily in water, but the solutions they form have
an important difference. One of those kinds of white crystals is an ionic compound, and when it
dissolves, it dissociates, or breaks up into ions. The ions are free to move in the solution, and that
solution, therefore, conducts electricity. The more ions in solution, the better it conducts electricity. The
other kind of crystal, however, is a molecular compound, and its molecules remain whole when they
dissolve. With no ions, that solution does not conduct electricity.
Use your knowledge of compounds to answer the following questions.
