The Project Can Be Completed on Regular Paper Or Poster Paper

Unit 2 “ ANTACIDS” Project

The project can be completed on regular paper or poster paper.

DUE Date: Monday, 10/13, 2014

Part A

Find 10 ionic compounds on the ingredient’s labels for foods or other household goods. The ionic compounds must be binary or ternary (contain polyatomic ions from the list on your reference table). Write the correct name of each compound and its correct chemical formula according to the IUPAC convention (not all foods and household good use IUPAC convention on the labels!). Mark or highlight the chemicals you included on your list on each of your labels. You are likely to need several foods/household goods to complete this part.. Include the original label or a picture of the original label with the name of the item and the ingredients list. Your list of 10 compounds MUST be in alphabetical order by the name of the compound and recorded in the provided table.

Part B

Write one of each of the following types of chemical equations: synthesis, decomposition, single replacement and double replacement. Each of these equations MUST use a unique ionic compound from the list your list from part A (you can’t use the same one twice!).

·  Synthesis: you must use a binary ionic compound or a metal hydroxide from your Part A list as a product.

·  Decomposition, single replacement and double replacement, you must use one of your compounds from your list in Part A as the reactant.

You MUST use one of the models on your reference tables for each type of reaction. Your chemical equations must have all the correct formulas, must follow one of the models on your guidelines for predicting products of chemical reactions from your reference tables, and must be properly balanced with the lowest, simplest whole number coefficients.

Part C

Find a name-brand or store-brand antacid with an “antacid” active ingredient whose name is based on the IUPAC convention, and is either a binary ionic compound or ternary ionic compound (includes polyatomic ion(s) from the list on your reference tables). Write the correct name of the compound and its correct chemical formula according to the IUPAC convention. Include the original label or a picture of the original label with the name of the item and the ingredients list. Mark or highlight the active ingredient. If there is more than one active ingredient (whose purpose is “antacid”) use only one. Identify this active ingredient as an acid, a base, a salt, or “other”.

Part D

Write a chemical equation for the double replacement reaction with the active ingredient you used from Part C and any one of the 5 acids you are expected to know for this class. You must have all formulas correctly written, and you must correctly balance the equation with the simplest, lowest possible whole number coefficients.
