#1. 10th Mar 14, 1:38 PM. Is it possible to suffocate in your sleep? 10th Mar 14 at 1:38 PM. #1. I've got a bad cold at the moment, and yesterday morning I was in 1 of those states where you're asleep but you know you're asleep and you know what's going on, and you can feel what's going on.
The role of soil pH in the health of the lawn, and how MAG-I-CAL works to rapidly adjust the pH of the lawnâs soil. The pH level of the soil is an important consideration in growing lawns. Most of us have a basic understanding of pH as a way of measuring how acidic or alkaline a soil may be. If you own a swimming pool, you know that correcting and balancing the pH of the water you swim in is important.
The dissociation of water into hydrogen and hydroxide ions is the basis for the pH scale. The pH is related to the concentration of hydrogen ions by the formula, pH = -log[H + ]. It is a logarithmic relationship. When the concentration of hydrogen ion changes by a factor of 10, the pH changes by a factor of 1. Many chemical processes are pH dependent and careful control of pH is important consideration. Solution pH is an important property that is measured by means of a pH meter. A pH meter and its electrodes form a sensitive electrochemical device that will allow an accurate, reproducible, and reliable measurement of the pH of a solution (see Figure 1).
