E TEXT ANSWER Question 9 You observe two white granular solids in unmarked jars in your kitchen One of the substances is salt (NaCl), and the other is su (C_(12)H_(22)O_(11)) Explain how you could use the differences in properties between ionic and covalent compounds to determine whid salt and which one is sugar. You may choose different properties to contrast the compounds. You may start your response with: - To compare the two white granular solids, I will choose the properties of __

To compare the two white granular solids, I will choose the propertiesility in water and electrical conductivity.<br /><br />First, I will take a small amount of each solid and add it to a cup of water. I will observe which substance dissolves completely in the water. Salt (NaCl) is an ionic compound and will dissolve in water, while sugar (C_{12}H_{22}O_{11}) is a covalent compound and will also dissolve in water. However, salt will dissociate into its constituent ions (Na+ and Cl-) when dissolved, while sugar will remain as intact molecules.<br /><br />Next, I will take a small amount of each solid and rub it between my fingers. I will observe which substance feels smooth and slippery. Salt (NaCl) is an ionic compound and will feel rough and gritty, while sugar (C_{12}H_{22}O_{11}) is a covalent compound and will feel smooth and slippery.<br /><br />Finally, I will take a small amount of each solid and place it on a piece of paper. I will use a pencil to touch the solid and observe if it conducts electricity. Salt (NaCl) is an ionic compound and will conduct electricity, while sugar (C_{12}H_{22}O_{11}) is a covalent compound and will not conduct electricity.<br /><br />Based on these observations, conclude that the substance that dissolves completely in water, feels smooth and slippery, and conducts electricity is salt (NaCl), while the substance that does not dissolve completely in water, feels rough and gritty, and does not conduct electricity is sugar (C_{12}H_{22}O_{11}).
