Whether in the UK or in the US, the mass of the copper in a copper alloy penny can be determined. If you are in the US, just note that on the lab sheet, a penny is identified as a "1p piece." The penny is dissolved by young chemists in nitric acid. They treat the resulting solution in order to form an iodide precipitatet. Finally, they titrate the solid with sodium thiosulphate and then use the amount to calculate the mass of copper. This is a top-notch lab to challenge your chemists with!
In this titrimetric analysis worksheet, high schoolers determine how much copper is actually in a copper coin. They titrate an iodine solution make from the coin with sodium thiosulphate to determine the mass of the copper present. Students solve 10 post lab questions and write an evaluation of the lab.
For this chemistry worksheet, students complete 10 short answer review questions about pH, molarity of solutions, acid/base indicators, and titration.
Students write and balance five chemcial equations which have been observed throughout the process of completing the experiment. They use vacuum filtration to recover suspeneded particals from a colloidal suspension. Students correctly identify the copper or copper minerals in a recoverd sample of copper material
Future scientists are introduced to the chemical consequences of burning fossil fuels, learning that fossil fuel combustion leads to the formation of oxides of three nonmetals: carbon, nitrogen, and sulfur, all of which end up in the atmosphere and water. They explore how when each of these oxides are added to water, an acid forms, in addition to threatning wildlife in our streams, lakes, and rivers, acids react with building materials as carbonate containing rocks and some metals.
Students perform experiments to determine how different acids cause acid rain. They measure the pH of the water to calculate the water's acidity. They discover how acid rain dissolves rock materials.
In this chemical equations worksheet, students are given 37 word equations and they complete each by filling in the product or reactant that is missing using words.
In this acids, bases and salts activity, learners answer sixty three questions about ionization, pH, pOH, strong acids and bases, equilibrium and salts. They write formulas for acids and bases, they identify conjugate acids and bases and they find pH and pOH of solutions.
In this chemical detectives worksheet, students perform 6 tests on various unknown solutions including a test for chloride ion, sulphate ions, carbonate ions, iron (III) ions, iron (II) ions and copper (II) ions. Students record their tests, take down observations and make an inference about each result.
Learners examine the properties of solids, liquids, and gasses. For this states of matter lesson, the teacher guides students through a series of experiments to illustrate each state of matter and how matter changes from one state to another.
The pH, concentrations, and formulas are needed to complete this worksheet. Pupils should be able to list physical and chemical properties and then provide definitions and equations for common bases and their reactions. Space is provided for equations of dissociation and for the graphs for the titrations given. This is a very complete set of problems and could be used for a review packet, or even as a test set.
Learners observe examples of physical changes that can take place between the three states of matter and develop common sense and intuition in distinguishing between chemical and physical changes. They observe diagrams on the board from which they identify the one that is not a physical change and explain the difference between a physical and chemical change.
Students perform a series of experiments on copper to produce a variety of copper compounds. In this chemical reactions of copper lesson plan, students use copper wire and nitric acid to produce copper nitrate. They then form a hydroxide followed by an oxide and they regenerate the initial copper. They answer 3 questions about the experiment.
For this chemistry worksheet, students identify and solve for the pH in each of the acidic solutions listed. There are twenty different combinations to solve.
In this salts worksheet, students read how salts are created and how different acids make different salts. This worksheet has 1 graphic organizer and 7 short answer questions.
In this chemistry activity, students practice creating chemical equations given the names of the compounds. The answers are included in the set of sheets.
Students identify the physical and chemical properties and explore the differences. In physical and chemical property lesson students test polymers for the differences between the physical and chemical properties, record their observations and orally, and in writing communicate their results.
Students explore the difference between physical and chemical change.
Young scholars study acid rain and complete several activities that show how it affects the environment. They role play members of the community involved in a major decision involving the protection of the environment.
Students work together to research water quantity, quality and safety standards. They complete a lab to discover how to use the water from an air conditioner. They write a paper to show their findings.
