Chem 11 Demos.pdf
This document gives 85 demonstrations that fit into the Chemistry 11 curriculum and illustrate specific concepts.

Chem 11 Demos.Appendix.pdf
This document can be printed out on 81/2 x 14” paper to give a special periodic table for use with Chem 11 demonstration number 11.VIII.5.

Chem 11 Student Demographics.doc - NEW 2009
An information sheet that students fill in for the teacher (parent access, previous science and math marks, important health problems, timetable, future plans, etc.)

Extra Unit Conversions.doc - NEW 2009
A set of 15 extra unit conversion exercises for students requiring more help to “catch on” to working with unit conversions.

Answers to Extra Unit Conversions.doc - NEW 2009
Answers to the extra 15 unit conversion exercises.

General Info Chem 11.doc - NEW 2009
A student handout giving an overview of Chem 11 and its expectations, comments on tests, marks, work habits, letter grades, policy on missed tests, lab report policy, mathematics requirements, availability of extra help and policy on cheating. This document must be modified to conform to individual teacher, school and district policies.

Multiple Solubility.doc - NEW 2009
Instructions for creating a solution that is simultaneously saturated with 4 different substances: sucrose, ammonium nitrate, sodium acetate and potassium bromide. The resulting solution is stable for years and quite viscous.

Wordsearch Chemical Elements.doc - NEW 2009
Word search puzzle containing the names of the first 103 elements.

Analysis of Limestone.doc
Students analyze a sample of limestone to find how much calcium it contains. Mole calculations and gravimetric methods are used.

Analysis of Zinc Tablets.doc
Students use titration techniques to analyze a commercial tablet of a zinc supplement. They have to decide which of several reaction equations is correct and calculate the mass of zinc in the tablet.

Antacid Titration.doc - NEW 2009

Cu-Al Stoichiometry.doc
The object of this experiment is to find experimentally the mole ratio existing in the reaction between aluminum metal and copper (II) sulphate. Uses titration and stoichiometry calculations.

Density of CLPA Crystals.doc
An introductory lab for Chem 11. Students determine the mass, volume (and density) of a small pellet of cross-linked polyacrylamide (also known as superabsorbent polyacrylamide or “water gel crystals” from Educational Innovations) before and after the pellet swells hundreds of times larger in water.

Density of Water-Alcohol.doc
Students determine the mass and volume of different mixtures of water and alcohol. Gives practice in hypothesizing, accurate measurements; find a volume contraction of the mixture.

H2SO4-NaOH Titration.doc
Students titrate a solution of sulphuric acid having an unknown molarity with a solution of sodium hydroxide having a known molarity.

Isolation of Caffeine.doc
Students practice numerous separation procedures as they obtain pure caffeine from tea leaves. Does not use chloroform.

Percentage Composition.doc
The object of this experiment is to find the actual chemical equation which governs the manner in which baking soda (sodium hydrogen carbonate, NaHCO3) decomposes. Students must devise a method of their own and decide what calculations will be needed. They are given a few guidelines to help them.

Prep’n of NiSO4.doc
Students prepare crystals of nickel(II) sulphate in a series of reactions, starting from “nickel tokens”. Involves stoichiometry calculations.

Spectrophotometry of Cu2+.doc
The purpose of this experiment is to use a spectrophotometer to prepare a graph of light absorbance versus concentration and use it to estimate the unknown concentration of copper(II) ions in a solution.

Synthesis of Cu(II) Benzoate.doc
Students gain practice in mole calculations as they prepare a sky blue compound.

Synthesis of Orange II.doc - NEW 2009

TLC of Dyes.doc - NEW 2009
