The term “ تداول اسهم سمنت ام القر pH” was first described by Danish biochemist Søren Peter Lauritz Sørensen in 1909. The H is capitalized because it is standard to capitalize element symbols

الخيارات الثنائية استراتيجية ساعة واحدة وظيفة كبيرة للقراءة pH is a quantitative measure of the acidity or basicity of aqueous or other liquid solutions. The measurement of السمعة وسطاء الخيارات الثنائية pH is widely used in chemistry, biology, and agronomy, translates the values of the concentration of the hydrogen ion. A solution with a pH less than 7 is considered acidic; a solution with a pH greater than 7 is considered basic, or alkaline and a pH of 7 is considered neutral.
