This product is used in teaching these Australian Curriculum codes:
ACSCH066 - Molecular interactions and reactions - Aqueous solutions and acidity - The pH scale is used to compare the levels of acidity or alkalinity of aqueous solutions; the pH is dependent on the concentration of hydrogen ions in the solution
ACSCH064 - Molecular interactions and reactions - Aqueous solutions and acidity - The presence of specific ions in solutions can be identified using analytical techniques based on chemical reactions, including precipitation and acidbase reactions
ACSCH097 - Equilibrium acids and redox reactions - Chemical equilibrium systems - Acids are substances that can act as proton (hydrogen ion) donors and can be classified as monoprotic or polyprotic depending on the number of protons donated by each molecule of the acid
ACSCH101 - Equilibrium acids and redox reactions - Chemical equilibrium systems - Acidbase indicators are weak acids or bases where the acidic form is of a different colour to the basic form
ACSCH091 - Equilibrium acids and redox reactions - Chemical equilibrium systems - Over time, physical changes and reversible chemical reactions reach a state of dynamic equilibrium in a closed system, with the relative concentrations of products and reactants defining the position of equilibrium
ACSCH100 - Equilibrium acids and redox reactions - Chemical equilibrium systems - The pH scale is a logarithmic scale and the pH of a solution can be calculated from the concentration of hydrogen ions; Kw can be used to calculate the concentration of hydrogen ions from the concentration of hydroxide ions in a solution
ACSCH098 - Equilibrium acids and redox reactions - Chemical equilibrium systems - The strength of acids is explained by the degree of ionisation at equilibrium in aqueous solution, which can be represented with chemical equations and equilibrium constants (Ka)
ACSCH102 - Equilibrium acids and redox reactions - Chemical equilibrium systems - Volumetric analysis methods involving acidbase reactions rely on the identification of an equivalence point by measuring the associated change in pH, using chemical indicators or pH meters, to reveal an observable end point
