Abstract

A comparison was made of glass and quinhydrone electrodes for determining the pH of some Iowa soils. Particular attention was given to the "QH error" and the "QH electrode error," and also to any changes in the hydrogen-ion concentration of the soil as it is permitted to stand in contact with water. The modified bulb, silver-silver chloride type of glass electrode and the ordinary type of platinum electrode with quinhydrone were employed in making the determinations.
