What products will be formed in the reaction between potassium hydroxide and nitric acid?
Products are potassium nitrate and water. Here is the Word Equation Potassium hydrtoxide + nitric Acid = potassium nitrate and water. Here is the BALANCED reaction eq'n KOH(aq) + HNO3(aq) = KNO3(aq) + H2O(l) NB THere will be no precipitate. To isolate the product you need to evaporate the solution. NNB All Group (1) metal cations (K^+) and nitrate anions(NO3^-) are soluble.
What is the balanced equation for lead acetate and potassium iodide producing potassium acetate and lead iodide?
Pb2+ + I- --> PbI2(s)potassium and acetate ions are left out of the equation, because they don't react (stay unchanged in solution)
Can potassium cyanide kill when placed on wounds?
...from ashigakari.com ...no, because potassium cyanide can only kill when it is mixed with acid, producing hydrogen cyanide. in case of poisoning, the reaction occurs on digestion.
When a small piece of potassium is dropped into a beaker of water the potassium moves about rapidly and then ignites within secounds the metal is gone and all activity ceases Is that chemical change?
Yes, according to wikipedia: Potassium reacts very violently with water producing potassium hydroxide (KOH) and hydrogen gas.2 K (s) + 2 H2O (l) → 2 KOH (aq) + H2 (g) This is a chemical change.
Does barium nitrate and sodium chloride for a precipitate?
It depends on the solution in which the reaction producing it occurs. A precipitate is formed when a product of a reaction in an aqueous solution is not soluble. Instead of being dissolved in the solution, it 'precipitates' into a solid, which often is suspended in the solution and may cause a color change. Ba(OH)2 is soluble in water, and therefore will not produce a precipitate in water unless the water is over-saturated or at low temperatures.
What is nauru famous for producing?
Phosphate.
What are the materials of producing iodized salt?
Iodized salt contain potassium iodide (KI) or potassium iodate (KIO3).
What is the formula for perchloric acid plus potassium hydroxide producing water and potassium perchlorate?
HClO4 + KOH ----> KClO4 + H2O
What is formed when the product of a chemical reaction is insoluble?
Solutions producing an insoluble product during a reaction becomes a precipitant. It enables scientists to calculate the ions present in the solution.Ê
Identify the type of reaction and net ionic equations of the following:a.Zinc sulfide ore is heated in air producing zinc oxide and sulfur dioxide gas?
b. Calcium phosphate is heated with silicon dioxide and carbon, producing calcium silicate, phosphorus and carbon monoxide. c. Calcium dihydrogen phosphate reacts with sodium hydrogen carbonate producing calcium phosphate, carbon dioxide, water, and sodium hydrogen phosphate. d. Sulfur dioxide reacts with water to form sulfurous acid. e. (NH4)2SO4 (aq) + ZnCl2 (aq) →

Will calcium chloride and potassium react?
Yes. The potassium will replace the calcium in the calcium chloride, producing potassium chloride and calcium. This is an example of a single replacement/displacement reaction. CaCl2 + 2K --> 2KCl + Ca
What is the balanced equation for lead acetate and potassium iodide producing potassium acetate and lead iodide?
Pb2+ + I- --> PbI2(s)potassium and acetate ions are left out of the equation, because they don't react (stay unchanged in solution)
Is potassium intake dangerous?
Elemental potassium reacts violently with water producing potassium hydroxide, which is caustic. Potassium ions (from potassium compounds, which are more common than elemental potassium) can be toxic and are in fact used in lethal injections in the form of potassium chloride. However, we need a certain amount of potassium ions in order to survive at all.
Can potassium cyanide kill when placed on wounds?
...from ashigakari.com ...no, because potassium cyanide can only kill when it is mixed with acid, producing hydrogen cyanide. in case of poisoning, the reaction occurs on digestion.
Signs of chemical change?
Some signs are: change of the color, change in odor, release of a gas, change of the temperature, formation of a precipitate, pH modification, viscosity variation, etc.
What happens if K keep in air?
Potassium oxidizes immediately when exposed to air. It also reacts violently in water, producing potassium hydroxide and hydrogen gas. The hydrogen gas produced will burn spontaneously, so potassium is always stored in a liquid with which it does not react, such as kerosene.
