They occur <a href=\"http:\/\/www.experimentoscientificos.es\/en\/reacciones-acido-base-teoria\/\">acid-base reactions<\/a>, <a href=\"http:\/\/www.experimentoscientificos.es\/en\/reacciones-quimicas-redox\/\">oxidation-reduction reactions<\/a>\u00a0and solubility. All these reactions are essential to maintain the marine ecosystem. They are also essential to maintain the <a href=\"http:\/\/www.experimentoscientificos.es\/en\/corriente-del-golfo\/\">regulatory functions of the ocean on the planet's climate<\/a>. A variation in either the chemistry of the ocean or the ecosystem can affect the entire behaviour of the ocean.  The ocean (or sea) is a large ecosystem in equilibrium between the marine ecosystem, the atmosphere and the chemical reactions that occur in it.  It will remain so as long as it is able to absorb all deviations and maintain equilibrium.<\/p>\n<p>Let's see how this great equilibrator of marine life, temperature, CO2 and marine components works.<\/p>\n<h2>HOW MUCH IS THE PH OF SEAWATER<\/h2>\n<p><strong>The pH of seawater is a fairly constant value between pH 7.4 and 8.5. Here we explain how it remains constant.<\/strong><\/p>\n<p>One of the first values to be affected, and which measures the tendency of water to become unbalanced, is pH. If you are not familiar with the term pH, here is all the information you need to know about it. <a href=\"http:\/\/www.experimentoscientificos.es\/en\/ph\/\">pH<\/a>and here about the <a href=\"http:\/\/www.experimentoscientificos.es\/en\/ph-del-agua\/\">Water pH<\/a>.<\/p>\n<p>The sea water is slightly <strong>alkaline<\/strong>The values of these values are between a value of <strong>pH 7.4 and 8.5<\/strong>. An acidification (below 7.4) or alkalinisation (above 8.5) of the ocean would mean a change in the conditions of life in the sea as we know it today.<\/p>\n<h3>HOW THE PH VALUE IS KEPT IN EQUILIBRIUM<\/h3>\n<p>The pH of seawater is constantly being altered. From the absorption of CO2 by the sea, the emission of gases from marine plants, to all the waste from fish and of course from human waste.<\/p>\n<p>All this would upset the balance in the ocean were it not for the great pH balancer that exists. <strong>Thanks to the ocean's ability to balance, life in the ocean and on the planet as we know it is maintained.<\/strong>. This is how this great balancer or <strong>pH buffer:<\/strong><\/p>\n<ul>\n<li>The ocean absorbs much of the CO2 emitted (helping to eliminate greenhouse gases, or make their effect less pronounced).<\/li>\n<li>Part of the absorbed CO2 is transformed into carbonic acid HCO3.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2>MEASURING THE PH OF SEAWATER<\/h2>\n<p>In the section on pH of water, you can see how to measure the pH of water.
