The doctor may recommend medication to lower your blood pressure; there are several medications that are used to control high blood pressure. 1.) Diuretics‚ it acts on the kidneys to help your body eliminate sodium and water‚ reducing blood volume. 2.)Beta-blockers reduce the workload of the heart and open the blood vessels. 3.) Angiotensin-converting enzyme inhibitors help to relax blood vessel and the Angiotensin II receptor blockers also help relax blood

diarrhoea. 2. Why “reduced osmolarity”? Studies have shown that the efficacy of ORS for treatment of children with acute diarrhoea is improved by reducing its sodium concentration to 75 mEq/l‚ its glucose concentration to 75 mmol/l‚ and its total osmolarity to 245 mOsm/l. This compares to the original solution which contained 90 mEq/l of sodium with a total osmolarity of 311 mOsm/l.

their compounds. Common catalysts include manganese dioxide‚ silver‚ and platinum. The same reaction is catalysed by the enzyme catalase‚ found in the liver‚ whose main function in the body is the removal of toxic byproducts ofmetabolism and the reduction of oxidative stress. The decomposition occurs more rapidly in alkali‚ so acid is often added as a stabilizer. The liberation of oxygen and energy in the decomposition has dangerous side-effects.

Aqueous Solution by Iodometric Titration Results and Discussion Oxidation-reduction titration is a kind of volumetric analysis where the titrant used undergoes a redox reaction with the analyte. In this experiment‚ the oxidation of iodide (I-) to produce iodine (I2) is taken into consideration. The use of this concept in a redox titration is called iodometry. Iodimetry‚ on the other hand‚ deals with the reduction of I2 into I-. Between these two methods‚ iodometry is more popular because it
