Answer 1

pH is determined by measuring the hydrogen ion activity in an aqueous solution. A glass electrode, calibrated against a pH standard is used to do this. A sub-sample of soil is mixed with water or CaCl2 at a ratio of 1 part soil to 5 parts liquid and the pH of the suspension is measured after 1 hours shaking.
