Molar mass calculator computes molar mass, molecular weight and elemental composition of any given compound.
Production[ edit ] Approximately 1. It does not form a hydrate, unlike sodium sulfate. The salt crystallizes as double six-sided pyramids, classified as rhombic. They are transparent, very hard and have a bitter, salty taste. The salt is soluble in water, but insoluble in solutions of potassium hydroxide sp.
When potassium sulfate is heated in water and subject to swirling in a beaker, the crystals form a multi-arm spiral structure when allowed to settle. K2SO4 does not contain chloride, which can be harmful to some crops. Potassium sulfate is preferred for these crops, which include tobacco and some fruits and vegetables. Crops that are less sensitive may still require potassium sulfate for optimal growth if the soil accumulates chloride from irrigation water.
Potassium sulfate is also used as a flash reducer in artillery propellant charges. It reduces muzzle flash , flareback and blast overpressure. It is sometimes used as an alternative blast media similar to soda in soda blasting as it is harder and similarly water-soluble.
The solution behaves much as if its two congeners , K2SO4 and H2SO4, were present side by side of each other uncombined; an excess of ethanol the precipitates normal sulfate with little bisulfate with excess acid remaining.
The behavior of the fused dry salt is similar when heated to several hundred degrees; it acts on silicates , titanates , etc. Hence it is frequently used in analytical chemistry as a disintegrating agent. For information about other salts that contain sulfate, see sulfate.
This program was created with a lot of help from: The book "Parsing Techniques – A Practical Guide" (IMHO, one of the best computer science books ever written.); The Gold Parsing System (Hats off! What a great software product!) The Calitha – GOLD engine (c#) (Made it …
Oct 20, 2009 · Thats close however, since the copper sulfate has a charge of +2 ( this is known due to the anion sulfate having a -2 charge and the molecule being neutral) the …
A grower should select a low salt form of K and avoid anything with KCl or KSO4 for foliar applications. A better and safer means is to address the situation by applying potassium before planting 2013. Walk your fields now and note where you’re seeing signs of potassium deficiency, so you can be sure to test and possible treat those areas …
硫酸カリウム（りゅうさんカリウム、potassium sulfate）は化学式 K 2 SO 4 の無機化合物である。 硫酸カリ、硫加（リュウカ）とも呼ばれる。不燃性の白色結晶塩で、水には溶けるがアルコールには溶けない。 天然にはアルカナイトとして存在するが、これは存在度の低い鉱物である。
May 28, 2020 · There are three main steps for writing the net ionic equation for KI + CuSO4 = K2SO4 + CuI2 (Potassium iodide + Copper (II) sulfate). First, we balance the m…Author: Wayne Breslyn
Nov 01, 2010 · p. 3 may produce explosion. Crystals of potassium permanganate explode vigorously when ground with phosphorous. A mixture of .5% potassium permanganate + ammonium nitrate explosive caused an explosion 7 hrs. later.
General description Potassium tellurite is a hygroscopic granular white powder. It decomposes at 460-470 o C. . Application Potassium tellurite along with agar may be used as a component of a selective medium for growth of bacteria.
Potassium hydrogen sulfate is a colorless crystalline solid with a sulfur odor. It may cause illness from ingestion. If heated to high temperatures it may emit toxic fumes. It is used to make fertilizers and wine.
