Question

1. based on the type of elements involved, predict whether each of the following compounds is primarily ionic or primarily not ionic. (hydrogen is usually considered a nonmetal).

• sodium chloride (nacl)
• copper (ii) sulfate (cuso₄)
• potassium chloride (kcl)
• magnesium sulfate (mgso₄)
• sucrose (aka sugar) c₆h₁₂o₆

1. in your own words, what is an ionic bond?

procedures:
station 1: internet lookup of melting points
materials: any ipad or chromebook

1. look up the melting points for each of the five solids and record the values in data table 1

data and observations:
data table 1: solubility and conductivity observations of ionic compounds

Explanation:

Ionic compounds are formed from the transfer of electrons between metals and non - metals. Sodium chloride (NaCl) has Na (metal) and Cl (non - metal), copper (II) sulfate ($CuSO_4$) has Cu (metal) and S, O (non - metals), potassium chloride (KCl) has K (metal) and Cl (non - metal), magnesium sulfate ($MgSO_4$) has Mg (metal) and S, O (non - metals), so they are ionic. Sucrose ($C_6H_{12}O_6$) has C, H, O (all non - metals) and forms covalent bonds (sharing of electrons), so it is not ionic.

Answer:

Sodium chloride (NaCl): ionic
Copper (II) sulfate ($CuSO_4$): ionic
Potassium chloride (KCl): ionic
Magnesium sulfate ($MgSO_4$): ionic
Sucrose ($C_6H_{12}O_6$): not ionic
