WebNov 29, 2016 · Posted on the 29th of Nov 2016 by Westlab. Temperature plays a significant role in pH measurements. As the temperature rises, molecular vibrations increase which results in the ability of water to ionise and form more hydrogen ions. As a result, the pH will drop. The dissociation of water into hydrogen and hydroxide ion can be represented as: The chart above is for solution temperature compensation. It’s the calibration solutions pH value at X temperature. This chart should only be used during calibration. It can not be used to validate your temperature compensated readings.

WebFor those growing in soil, your root zone should be measuring within the 6.5-7 pH range. That said, certain plant crops may thrive in more acidic or alkaline environments, so always look up the preferred pH range for the plants you're planning to grow. See the chart below for our recommended pH ranges for some of the most commonly grown crops: WebThe pH electrode behaviour follows the Nernst equation: E = E0 + 2.303 (RT/nF) log aH+ where slope, also called sensitivity, is denoted by -2.303 RT/nF and pH is equal to -log aH+. Since R, F, and n are constants, the slope changes with temperature and this effect can be compensated by a pH meter with ATC capability. Click image to enlarge.
