Sobre la utilización directa de un agua de mar cualquiera como agua patrón auxiliar para la determinación de la clorinidad de las aguas marinas

Abstract

[ES] Precisándose conocer periódicamente en este Laboratorio de Biología Marina la salinidad y densidad de ls aguas de la región pesquera que es objeto de nuestras investigaciones, hemos tratado de hallar un método que nos permitiera determinarlas aplicando el de Mohr-Knudsen sin hacer uso de agual normal internaciona, de la cual carecemos. [...] Después de hacer una somera crítica de los métodos hasta la actualidad propuestos para determinar la clorinidad de las aguas marinas y en especial las del Mediterráneo, se propone el uso de un agua de mar cualquiera de clorinidad conocida como agua auxiliar patrón para ser utilizada en el método de Mohr-Knudsen, indicando el modo especial con que deben utilizarse las Tablas Hidrográficas, y conseguir un ahorro de agua normal de Copenhague. Para determinar la clorinidad de esta agua auxiliar se ha utilizado a i7°5 C. una disolución de CINa de 32'7443 g,/litro (volumen medido a I7°5 C.) en sustitución del agua normal internacional. Se indican algunas modificaciones en la práctica de las valoraciones para hacer más aparente y preciso el punto final

[EN] After a brief criticism of the methods just now proposed to determine the chlorinity of sea waters, specially those of Mediterranean, the use of any sea water the chlorinity of which is known, as an auxiliary standard water to be used in Mohr-Knudsen’s method is proposed, giving also the special form of using Hydrographical Tables and to attain an economy of standard water from Copenhague. To determine the chlorinity of this auxiliary water use is made (at 17’5° C) of a sodium chloride solution, containing 32’7443 g. NaCl per liter (volume measured at 17’5° C), instead of the International standard sea water. It is also given some amendments in the practice of the valuations to malve its end point more apparent and exact
