Use the passage below to answer the question. To test soil pH, take a colorimetric test kit and place a half teaspoon soil on the plate. Then, add dye to the soil until it is saturated, and mix it well. Subsequently, add barium sulphate and wait for a change in color. Finally, compare the soil color with the pH color chart and record the result. Alternatively, measure soil pH using a pH meter. Firstly, fill the jar with soil without compressing it. Pour five lids of distilled water, screw the lid tight, and shake it well. Then, wash and wipe the pH meter electrode before opening the jar gently. Subsequently, immerse the electrodes in water without touching the settled sediment; then stir the solution gently and wait for the reading to stabilize before recording it. Stimulus: 1 of 2 Which of the following step sequences should be taken to measure soil pH using a colorimetric test kit? Put barium sulphate on the plate, add dye, mix them well, add the soil sample, observe the change in color, compare the color w
