    Learning Objectives

    By the end of this lab, students should be able to:

    • Name mono- and polyatomic ions, according to IUPAC rules.
    • Differentiate between ionic and covalent compounds and their naming conventions, according to IUPAC rules.
    • Convert between the formula of a compound and its name, vice versa.
    • Identify and name weak and strong acids.

    Prior knowledge:

    Chemical Nomenclature is a set of rules that was developed to ensure generation of systematic names for chemical compounds. In other words, we need to follow nomenclature rules to make sure that we use the same name for the same compounds so other people can understand us. The nomenclature used most frequently worldwide is the one created and developed by the International Union of Pure and Applied Chemistry (IUPAC). 

    Deeper Look

    Ionic compounds consist of cation (positively charged) and anions (negatively charged) that are held together by electrostatic attraction. Most of the time in an ionic compound you will find a metal bonded to non-metal. These compounds can be made out of monoatomic or polyatomic ions. 

    Covalent compounds are two or more non-metals that are held together by covalent bonds. Acids are also covalent compounds.

    Molecular formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus and minus signs. When multiple atoms are held together by covalent bonds they form a single chemical entity, which we call a molecule. As postulated in Dalton's atomic theory, the ratio of the atoms of the different elements are whole numbers, and this can be described by the molecule's molecular formula.

    Pre-Lab Assignment

    This pre-lab assignment is an individual assignment to be completed on your own with the help of the "Prior Knowledge" links at the top of this page. All work must be in your own words. Do not copy and paste information from the internet. The assignment will be due 10 minutes before your lab begins. Late work will not be accepted.

    The document below is a preview only. You will be able to find your assignment to work on in your Google Classroom.

    In-Lab Assignment

    In this one week lab, you will be working on your own Individual Assignment while in Zoom Breakout Rooms with your group members. Each person must work on their own assignment, but your group members and your lab instructor will be available for help. You must use the correct formatting for writing formulas, names, and ions (i.e. use superscripts, subscripts, parentheses, and capital/lowercase letters when appropriate.) This assignment will be due by the end of your lab period. No late work is accepted.

    Post-Lab Problem Set

    After you have had a chance to complete your assignment during lab, you will be given the Nomenclature Post-Lab Problem Set. This is an individual assignment that must be completed on your own, and it is based on your Pre-Lab Primer and your In-Lab Assignment. This assignment will be due the day after your lab meets by 5 p.m. For example, if your lab is on Monday, the Post-Lab Problem Set will be due on Tuesday at 5 p.m. No late work is accepted.
