What chemical is used to make purple fireworks?
I would say Potassium is the closest chemical to a purple as it is a lilac/purplish colour.
What is the reaction of potassium chromate with strontium nitrate?
When potassium chromate (K₂CrO₄) reacts with strontium nitrate (Sr(NO₃)₂), a double displacement reaction occurs, resulting in the formation of strontium chromate (SrCrO₄) and potassium nitrate (KNO₃). The balanced chemical equation for this reaction is: [ K_2CrO_4 + Sr(NO_3)_2 \rightarrow SrCrO_4 + 2 KNO_3 ] Strontium chromate is a yellow precipitate, indicating the occurrence of the reaction.
What type of chemical reaction occurs when a disposable lighter is used?
What is the chemical reaction of a dispoiable lighter
Do the compounds remain the same as before the reaction when a chemical reaction occurs?
true
What chemical reaction occurs when gasoline and air are ignited?
Combustion is an oxidation reaction.
What happens when potassium nitrate is added with citric acid what reaction is it?
When potassium nitrate is added with citric acid, a chemical reaction occurs that results in the formation of carbon dioxide gas, water, and potassium citrate. This reaction is an acid-base reaction between citric acid and potassium nitrate.
What reaction happen between iron and potassium chloride?
When iron reacts with potassium chloride, a single displacement reaction occurs. The iron displaces potassium in the compound, forming iron chloride and potassium metal. The balanced chemical equation for this reaction is 2Fe + 2KCl -> 2K + 2FeCl3.
What will happen when potassium and water together what kind of changes?
When potassium metal and water are mixed, a chemical reaction occurs. This exothermic reaction produces hydrogen gas and potassium hydroxide, which dissolves in the remaining water. This reaction can be vigorous and produce light, heat and sound.
What happens when Solid potassium oxide is added to a container of carbon dioxide gas?
When solid potassium oxide (K2O) is added to a container of carbon dioxide (CO2) gas, a chemical reaction occurs. Potassium oxide reacts with carbon dioxide to form potassium carbonate (K2CO3). This reaction is a double displacement reaction, where the potassium from potassium oxide replaces the carbon in carbon dioxide, resulting in the formation of potassium carbonate. The balanced chemical equation for this reaction is: K2O + CO2 → K2CO3.
What occurs when potassium reacts with chlorine to form potassium chloride?
When potassium reacts with chlorine to form potassium chloride, a chemical reaction occurs in which potassium atoms lose an electron to form potassium ions, and chlorine atoms gain an electron to form chloride ions. These ions then combine to form a crystal lattice structure of potassium chloride, which is a white, crystalline salt. The reaction is exothermic, releasing energy in the form of heat.
What is the reaction of acetone sodium hydroxide and potassium iodide?
When acetone is mixed with sodium hydroxide and potassium iodide, no significant chemical reaction occurs due to the absence of a strong oxidizing or reducing agent in the combination. The reaction is non-redox and no new compounds are formed.
What happens when mix potassium to hydrochloric acid?
When potassium is mixed with hydrochloric acid, a chemical reaction occurs producing potassium chloride and hydrogen gas. The reaction is exothermic, meaning it releases heat and potentially sparks or flames. It is important to handle this reaction carefully in a controlled environment due to the potential hazards.
What is the reaction between potassium bicarbonate and magnesium chloride?
When potassium bicarbonate reacts with magnesium chloride, a double displacement reaction occurs. The products of this reaction are potassium chloride and magnesium bicarbonate.
What is reaction between aluminum and potassium nitrate?
When aluminum is mixed with potassium nitrate, a reaction occurs where aluminum displaces potassium to form aluminum nitrate and potassium nitride. The reaction is exothermic, producing heat and light.
What happens when potassium react with gold?
When potassium reacts with gold, a violent chemical reaction occurs that releases a significant amount of heat and can result in an explosion due to the extreme reactivity of potassium. This reaction is not commonly performed due to the dangerous and explosive nature of the reaction.
What happens when potassium hydroxide mixed with lithium?
When potassium hydroxide is mixed with lithium, a single displacement reaction occurs. Lithium will replace potassium in the potassium hydroxide solution, resulting in the formation of lithium hydroxide and potassium metal as products. The reaction is represented by the following chemical equation: 2Li(s) + 2KOH(aq) -> 2LiOH(aq) + 2K(s).
A solution of potassium iodide is treated with iron III nitrate solution?
A chemical reaction occurs where iron III iodide is formed and potassium nitrate is produced as a byproduct. The balanced chemical equation for this reaction is 2KI + Fe(NO3)3 -> 2KNO3 + FeI3. Iron III iodide is a dark brown solid, whereas potassium nitrate remains in solution.
