    difference between potassium and sodium was not discovered until the 18th century. "Vegetable alkali" also known as potassium carbonate came from the earth. "Mineral alkali" also known as sodium carbonate came from wood ashes. Early chemists did not recognise that these were two different chemical compounds. Sir Humphry Davy discovered potassium in 1807 in England, by isolating it using electrolysis. Potassium was the first metal to be isolated by using electrolysis. The name potassium originated from

    Potassium Potassium is a vital element in the human body. Potassium had never been distinguished between sodium until the eighteenth century. Before potassium was recognized as an element, potassium carbonate was mixed with animal fat to make soap. It was discovered by Sir Humphrey Davy in England, in 1807. Sir Davy was able to isolate potassium using electrolysis. Potassium was the first metal isolated by this procedure. Today, it is still not found free in nature. It is obtained by electrolysis

    Potassium is freely filtered in the glomerulus. Two thirds of the potassium is reabsorbed along the proximal tubule. The potassium concentration in the proximal tubule is roughly equal to that of plasma. In the descending limb of Henle a small amount of potassium is secreted into the luminal fluid and is reabsorbed by the ascending limb of Henle. The concentration of potassium is the distal convoluted tubule is now lower than the concentration in the plasma. The connecting tubule and cortical connecting

    1. Purpose of potassium within the plant To begin the process, potassium is a vital nutrient to productively grow many plants, although potassium isn’t an active ingredient of the chemical structure it still plays several significantly high roles in the development. There are several roles potassium does such as enzyme activation, photosynthesis, stomatal activity, transportation of sugars, water and nutrient transportation, starch synthesis, and improving the quality of the desired crop. 2. How

    placed accordingly on the table. Potassium is in the alkali metals which is placed in group 1 of the table, alkali metals are among the most active metals. This element was found in 1801 by a man named Humphry Davy. Although the element does not have many uses in pure form as a compound it has many important purposes. Potassium is naturally in the human body if levels become too low or too high then it could cause problems for the individual. Low levels of potassium could cause muscle problems such

    This investigation sought to determine the effect of changes in extracellular potassium concentration [K+] on resting membrane potential in the muscle cells of the adult crayfish Orconectes rusticus. Due to the knowledge of the highly negative equilibrium potential of K+, which, in normal, biological conditions, causes the ion to be transported toward more negative regions, it was hypothesized that as the extracellular [K+] increased, [K+] inside the cell would also increase. This would cause intracellular

    Potassium is an element on the periodic table that is symbolized by the letter K. The atomic number of this element is 19. At room temperature this element is a solid. Potassium can be found in two forms: either pure or compounds. Pure potassium is described as a soft silvery-white alkali metal that oxidizes rapidly in air and is very reactive in water However, Potassium forms many compounds such as Potassium chloride, which is the most common potassium compound (Gagnon, 1). This form of Potassium

    What is Potassium? Potassium (K+) is an important mineral the body needs to maintain and regulate many functions in the body. It is essential to life because it helps balance body water, regulate blood pressure, maintain heart function, and facilitate various cellular and tissue functions. Its function inside the cells is influenced by it positive electrical charge, which makes it a cation and an electrolyte, or a substance that regulates the flow of molecules, particularly water, across cell membranes

    Solubility of Potassium Chlorate Solubility is the maximum amount of solid that will dissolve in 100g of solvent. The solubility of a substance depends on the type of ionic particles in it. So the solubility of each substance is different. The formula of solubility is: SOLUBILITY(g/100g)= (SOLUTE / SOLVENT) * 100 I did an experiment to prove this and find the solubility of potassium chlorate, an ionic solid. Apparatus: 2g potassium chlorates, some distilled water, a stand, a

    The Solubility of Potassium Nitrate Aim To investigate how the solubility of Potassium Nitrate is affected by Temperature. Background Knowledge Potassium Nitrate (KNO3) is an ionic compound. The strong ionic bonds hold the compound in an ionic lattice which gives KNO3 its crystalline structure. These ionic bonds also have other properties which will affect my investigation, I must be aware of these properties for greater accuracy in my method. The ionic bonds give KNO3 high melting
