Vernier's general purpose pH Sensor can be used across disciplines including chemistry, biology, middle school science and environmental science.

Use the pH Sensor just as you would a traditional pH meter with the additional advantages of automated data collection, graphing and data analysis.

Typical activities using the Vernier pH sensor include:
• Acid-base titrations
• Studies of household acids and bases
• Monitoring pH change during chemical reactions or in an aquarium as a result of photosynthesis
• Investigations of acid rain and buffering
• Analysis of water quality in streams and lakes

Consider the FPH-BTA Vernier Tris-Compatible Flat pH Sensor if you are studying Tris buffers or semisolids such a soil slurry.

    This product is used in teaching these Australian Curriculum codes:
    ACSSU187 - Chemical Sciences - Chemical Reactions - Different types of chemical reactions are used to produce a range of products and can occur at different rates
    ACSBL019 - Biodiversity and the interconnec - Describing biodiversity - Ecosystems are diverse, composed of varied habitats and can be described in terms of their component species, species interactions and the abiotic factors that make up the environment
    ACSBL021 - Biodiversity and the interconnec - Describing biodiversity - In addition to biotic factors, abiotic factors including climate and substrate can be used to and classify environments
    ACSBL029 - Biodiversity and the interconnec - Ecosystem dynamics - Models of ecosystem interactions (for example, food webs, successional models) can be used to predict the impact of change and are based on interpretation of and extrapolation from sample data (for example, data derived from ecosystem surveying techniques
    ACSCH063 - Molecular interactions and react - Aqueous solutions and acidity - The concentration of a solution is defined as the amount of solute divided by the amount of solution; this can be represented in a variety of ways including by the number of moles of the solute per litre of solution (mol L­1) and the mass of the solute pe
    ACSCH066 - Molecular interactions and react - 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 react - 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 reac - 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 reac - Chemical equilibrium systems - Acid­base indicators are weak acids or bases where the acidic form is of a different colour to the basic form
    ACSCH096 - Equilibrium acids and redox reac - Chemical equilibrium systems - Equilibrium position can be predicted qualitatively using equilibrium constants
    ACSCH091 - Equilibrium acids and redox reac - 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 reac - 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 reac - 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 reac - 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
    ACSSU176 - Biological Sciences - Ecology - Ecosystems consist of communities of interdependent organisms and abiotic components of the environment; matter and energy flow through these systems
    ACSSU179 - Chemical Sciences - Chemical Reactions - Chemical reactions, including combustion and the reactions of acids, are important in both non-living and living systems and involve energy transfer
