| Did conduct | Did not conduct | Solid sodium chloride | | | Solid sucrose | | | Distilled water | | | Alcohol | | | Tap Water | | | Distilled water and sodium chloride | | | Distilled water and sucrose | | | Alcohol and sodium chloride | | | Alcohol and sucrose | | |

Questions:

2). Did any of the liquids conduct an electric current? If so, which one(s), and please explain why or why not thoroughly?
The tap water contains ions and minerals that conduct electricity due to the charges within the water. Distilled water is a liquid covalent compound where there are no charges or minerals and ions floating around and thus no electricity is conducted. The conductivity of either

Which of the two solids must be an ionic compound? Why?

Sodium chloride is an ionic compound because sodium donates an electron to chlorine. This causes sodium to have a positive charge making it cation. Also this causes chlorine to have a negative charge making it an anion. Also, when NaCl was place in the previously unconducting distilled water, it created an electrical current with it’s electrical charged from being separated by the water. Sucrose, although may have been broken, was not composed of ionic compounds and therefore did not create an electrical current.

b). What ions are found in this compound?
In sodium chloride there is Na+ which is a cation that donated an electrical to chlorine. Also there is Cl- which is an anion that received an electron from sodium.

c). Why do these ions conduct electricity when dissolved but not in the solid state? Explain thoroughly.
In the solid state, the compound is neutral. There is no electrical charge. The positive of Na and the negative of Cl cancel each other out to create a neutral compound. When separate though, both have charged that conduct an electrical current.

d). Write a chemical equation to show what happens when this solid is dissolved in

    Background: First, a double-replacement reaction is when two cations in different compound switch anions, AX + BZ → BY. If either compounds are insoluble a precipitate occurs, and if there is no precipitate formed there is no reaction. Also, not all ionic compounds are soluble in water, and there are a few solubility rules that need to be followed (see Chapter 8 in book). Second, there is also something known as a neutralization reaction, here the reaction is between…

    Because the sodium ion is positively charged, it attracts the negatively charged portion of the water molecule (the oxygen atom) and repels the positively charged portion of the water molecule (the hydrogen atoms). Because the chloride ion is negatively charged, it attracts the positively charged portion of the water molecule and repels the negatively charged portion.…

    The reason that Sodium gives electrons when reacting with a substance such as Chloride instead of sharing electron in a reaction such as the Hydrogen and Oxygen forming water molecules can be found in the type of bond in each example reaction. Before I can identify the contrasting characteristics of each reaction, I must first acknowledge the reason atoms react with one another in the first place. Each element has a certain number of valence electrons, an example being Sodium having one valence electron. When elements react they are trying to get a full shell of eight valence electrons by either giving away, taking in, or sharing valence electrons. The best way I can think to describe how atoms decide which method to do is that atoms have their…
