During this time, the pH of surface ocean waters has fallen by 0.1 pH units. This might not sound like much, but the pH scale is logarithmic, so this change represents approximately a 30 …
WebThe Indian Ocean Naval Symposium ( IONS) is a series of biennial meetings between the littoral states of the Indian Ocean region. It provides a forum to increase maritime security cooperation,discuss regional maritime issues, and promote friendly relationships among the member states. [1] [2] [3] [4] History [ edit] WebIn 1923, chemists Johannes Nicolaus Brønsted and Thomas Martin Lowry independently developed definitions of acids and bases based on the compounds' abilties to either donate or accept protons (H + ions). In this theory, acids are defined as proton donors; whereas bases are defined as proton acceptors.
