Thus the alkalinity serves as an index of the admixture of river water with sea-water.
Iron and quinine citrate is used as a bitter stomachic and tonic. In the blood citrates are oxidized into carbonates; they therefore act as remote alkalis, increasing the alkalinity of the blood and thereby the general rate of chemical change within the body.
The result of this is that the alkalinity of the sea-water increases and the hydrogen-ion concentration decreases.
The increasing temperature raises the rate of animal metabolism, while the higher alkalinity is a stimulus to cell-division.
He also traced a connexion between alkalinity, temperature and current-density, and showed that these conditions should be mutually adjusted.
