The question isn't very specific (preferred for what?!), but sodium metal is less reactive than potassium. It is also slightly more abundant than potassium on Earth.
i think it is because sodium is produced more economically.
$$$$$$ Sodium is cheaper!!!!$$$$$$ They both work great for the same purposes and are very often interchangeable. (But potassium hydroxide makes much softer and, to me, more pleasant feeling soap than sodium hydroxide)
Sodium is produced more economically and thus is much lower cost than potassium. Sodium is also slightly easier to handle. Both are used extensively in industry but sodium metal is less reactive than potassium metal.
Nebraskans use a variety of minerals including sodium, potassium, and calcium. They are used directly by the body and in many industrial applications like chemical plants.
Potassium hydroxide can be used as a substitute for sodium hydroxide in a number of applications. It can be used in the manufacture of soap and biodiesel, as an electrolyte in batteries, and as a precursor to other potassium compounds.
At home sodium chloride is the essential condiment and preservative for foods. NaCl has also many industrial applications.
Sodium-Potassium pump uses ATP (energy) to pump sodium out of cells and potassium back in.
Potassium metabisulfite, K2S2O5, also known as potassium pyrosulfite, is a white crystalline powder with a pungent sulfur odour. The main use for the chemical is as an antioxidant or chemical sterilant. It is a disulfite and is chemically very similar to sodium metabisulfite, with which it is sometimes used interchangeably. Potassium metabisulfite is generally preferred out of the two as it does not contribute sodium to the diet.
Sodium is Na Potassium is K
Sodium - Na Potassium - K
K; Potassium
Sodium Potassium
No. The reaction of sodium hydroxide with sulfuric is more exothermic. And hence it is preferred to pour a solution of sodium bicarbonate or potassium bicarbonate in the case of spills.
