Overview

The development and use of materials for specific purposes is an important human endeavour. In this unit you will investigate the chemical structures and properties of a range of materials, including covalent compounds, metals, ionic compounds and polymers. They are introduced to ways that chemical quantities are measured. They consider how manufacturing innovations lead to more sustainable products being produced for society through the use of renewable raw materials and a transition from a linear economy towards a circular economy.

You will conduct practical investigations involving the reactivity series of metals, separation of mixtures by chromatography, use of precipitation reactions to identify ionic compounds, determination of empirical formulas, and synthesis of polymers.

Throughout this unit you will use chemistry terminology including symbols, formulas, chemical nomenclature and equations to represent and explain observations and data from their own investigations and to evaluate the chemistry-based claims of others.

A student-directed research investigation into the sustainable production or use of a selected material is to be undertaken in Area of Study 3. The investigation explores how sustainability factors such as green chemistry principles and the transition to a circular economy are considered in the production of materials to ensure minimum toxicity and impacts on human health and the environment. The investigation draws on key knowledge and key science skills from Area of Study 1 and/or Area of Study 2.

Overview

Society is dependent on the work of chemists to analyse the materials and products in everyday use. In this unit you will analyse and compare different substances dissolved in water and the gases that may be produced in chemical reactions. You will explore applications of acid-base and redox reactions in society.

You will conduct practical investigations involving the specific heat capacity of water, acid-base and redox reactions, solubility, molar volume of a gas, volumetric analysis, and the use of a calibration curve.

Throughout the unit you will use chemistry terminology, including symbols, formulas, chemical nomenclature and equations, to represent and explain observations and data from their own investigations and to evaluate the chemistry-based claims of others. 

A student-adapted or student-designed scientific investigation is undertaken in Area of Study 3. The investigation involves the generation of primary data and is related to the production of gases, acid-base or redox reactions, or the analysis of substances in water. It draws on the key science skills and key knowledge from Unit 2 Area of Study 1 and/or Area of Study 2.

Prerequisites

It is expected that students undertaking Units 1 & 2 Chemistry will have studied either Chemistry or Environmental Science at Year 10. Competency in Chemistry topics at the Year 10 level is presumed for Units 1 & 2.

Areas of Study

• How do chemicals interact with water?
• How are chemicals measured and analysed?
• How do quantitative scientific investigations develop our understanding of chemical reactions?

In the first area of study you will focus on understanding the properties of water and investigating acid-base and redox reactions. You explore water’s properties, including its density, specific heat capacity and latent heat of vaporisation. You write equations for acid-base and redox reactions, and apply concepts including pH as a measure of acidity. They explore applications of acid-base reactions and redox reactions in society.

In the second area of study you will focus on the analysis and quantification of chemical reactions involving acids, bases, salts and gases. You will measure the solubility of substances in water, explore the relationship between solubility and temperature using solubility curves, and learn to predict when a solute will dissolve or crystallise out of solution. You will quantify amounts in chemistry using volumetric analysis, application of the ideal gas equation, stoichiometry and calibration curves. 

The selection of learning contexts should allow you to develop practical techniques to investigate substances that may be dissolved in water or found in soils, particularly salts, acids and bases, as well as gases. You will develop your skills in the use of scientific equipment and apparatus. You will use precipitation reactions to purify water: for example, by using iron or aluminium compounds to precipitate and remove phosphorus from wastewater. You will perform acid-base titrations, such as comparing the ethanoic acid concentrations of vinegar, mayonnaise and tomato sauce. You will construct calibration curves to analyse unknown concentrations of substances, such as the amount of nitrates or phosphates in water or soil samples. You will respond to challenges such as determining the set of standards required in setting up a calibration curve in colorimetry.

Many of the 17 goals in the United Nations’ 2030 Agenda for Sustainable Development relate to ensuring that people have access to potable water, clean air and good quality soil to meet their basic needs. The quality of water, air and soil must be monitored closely to ensure that human health and the environment are not compromised.

In this area of study you will adapt or design and then conduct a scientific investigation related to chemical equations and/or analysis, which must include the generation of primary data. You will develop a research question related to the production of gases, acid-base or redox reactions or the analysis of substances in water, and adapt or design and then conduct a scientific investigation to generate appropriate quantitative data. You will organise and interpret the data and reach a conclusion in response to your research question.

Assessment

Assessment for Outcomes 1 and 2 may include: annotations of a practical work folio; a report of a practical activity; media response; problem-solving; data analysis; or a test.

Outcome 3 will be assessed by a report of a student-designed quantitative laboratory investigation using a scientific poster.
