Question

Prior to attending the laboratory period, complete the following activities in an organized Hallel lll your laboratory notebook. This assignment is due at the beginning of A. Introductory Statement in one paragraph, summarize in your own words (not the lab manual's) the purpose, theory and procedure for this laboratory experiment. B. Pre-laboratory Questions/Activities 1. what are found in ionic compounds? From an electron configuration types of elements standpoint, explain which elements form cations and which form anions. 2. What types found in molecular compounds? What properties of these elements of elements are account for their ability to form covalent rather than ionic bonds? 3. List several distinguishing properties of ionic and molecular compounds. 4. What are the 5 reference compounds you will be using in this lab? Based on their composition alone, classify each reference compound as either an ionic or molecular substance. 5. One of the reference substances is labeled "glacial" acetic acid. What does this term mean? C. Prepare the Data Section Prepare the Data Section of your lab notebook, beginning with the next page after the Pre-lab Questions/Activities. Copy the table below into your notebook. You will not submit the empty data pages as part of the Pre-lab (Introductory Statement and Pre-lab Questions/Activities), but the Data Section must be formatted before coming to lab. II. Data In your laboratory notebook, copy the following table for recording your data and observations. Below the table, allow space to answer the seven questions from the Procedure Section. & #2 Unknown Compounds: #1

Explanation / Answer

1. Ionic Compounds have ionic bond. Ionic bond is strong electrostatic force of attraction between cation and Anion and involve complete electron transfer.

Ionic bonds are formed between metals and non-metals. Metals have tendency to lose electron to achieve stable octet and hence they form cation. On the other hand non metals achieve stable octet by gaining electron and hence they form anions.
