What is the difference between hot acidified potassium manganate 7 and potassium manganate 7?
The term "hot acidified potassium manganate 7" typically refers to a solution of potassium permanganate (KMnO4) in acid, while "potassium manganate 7" refers to the solid compound potassium permanganate itself. The acid in the hot solution helps to increase the reactivity of the potassium permanganate.
What happens when zinc is added to the acidified potassium permanganate?
When zinc is added to acidified potassium permanganate solution, zinc displaces manganese from permanganate ions. This reduction reaction causes the purple color of the potassium permanganate solution to fade as the manganese ions are formed. The resulting solution may turn colorless or pink, depending on the concentration of the reactants.
How many atoms in K2SO4?
THe correct chemical formula of potassium sulfate is K2SO4; this molecule contain 7 atoms.
Why does acidified potassium permanganate turn from purple to colorless when added to an alkene?
When acidified potassium permanganate is added to an alkene, the purple color disappears due to the reduction of permanganate ions to colorless manganese dioxide. The alkene oxidizes the permanganate ions, causing them to be reduced and lose their color. This reaction is used to test for the presence of carbon-carbon double bonds in organic compounds.
What element forms a compound having the formula KXO4?
The element that forms a compound with the formula KXO4 is potassium. So, if you're looking for some potassium action, there you have it! Just remember, K is the symbol for potassium on the periodic table. Now go impress your friends with your newfound potassium knowledge!

What is the product of the reaction between cyclohexane and acidified potassium manganate VII?
The product of the reaction between cyclohexane and acidified potassium manganate VII (KMnO4) is cyclohexanol. This reaction involves the oxidation of cyclohexane to form cyclohexanol, facilitated by the oxidizing properties of potassium manganate VII in the presence of acid.
Is potassium manganate and potassium permanganate the same?
Potassium manganate = K2MnO4 Potassium permanganate = KMnO4 It is important to quote the oxidation state of the compound. Potassium manganate could easily be potassium manganate (VI) as opposed to potassium manganate (VII) KMnO4 Potassium manganate (VI) K2MnO4 is a dark green compound made by fusing manganese (IV) oxide with potassium hydroxide. It is stable in basic solution In aqueous acidic solution it disproportionates to the manganate (VII) ion and manganese (IV) oxide.
Why is potassium manganate 7 more soluble in hexane than water?
Potassium manganate 7 is more soluble in hexane than in water because it is a nonpolar solvent like hexane. Nonpolar solutes tend to dissolve better in nonpolar solvents, while water is a polar solvent. Therefore, the solubility of potassium manganate 7 is higher in hexane than in water.
What is the product of the reaction between ethene and acidified potassium manganate 7?
Here is the half equation for this reaction between sodium ethandioate and potassium manganate: 2MnO4- + 5C2O42- + 16H+ = 2Mn2+ + 10CO2 + 8H2O Carbon dioxide gas, water and sodium permanganate (a manganese (II) salt) is produced.
What is the formula for acidified potassium dichromate?
This is a mixture of 2K+ and Cr2O72- ions in strong sulfuric acid, made from potassium chromate.2CrO4- + 2H+ ----> Cr2O72- + H2Ochromate-yellow -> dichromate-orangeNote:Potassium ions do NOT react, they are tribune-ions
What is the chemical equation for the reaction between methanoic acid and acidified potassium permanganate?
The chemical equation for the reaction between methanoic acid (HCOOH) and acidified potassium permanganate (KMnO4) is: 2KMnO4 + 5HCOOH + 3H2SO4 → 2MnSO4 + K2SO4 + 5CO2 + 8H2O This reaction is a redox reaction where potassium permanganate is reduced from +7 to +2 oxidation state and methanoic acid is oxidized to carbon dioxide.
What colour change will occur when potassium manganate VII reacts with iron II sulphate?
When potassium manganate VII reacts with iron II sulfate, the purple color of potassium manganate VII will change to a pale pink or colorless solution due to the reduction of MnO4- to Mn2+. The iron II sulfate solution will become a pale green color due to the formation of Fe2+ ions.
What is the formular of zinc manganate?
Zn(Mno4)7
What happens when zinc is added to the acidified potassium permanganate?
When zinc is added to acidified potassium permanganate solution, zinc displaces manganese from permanganate ions. This reduction reaction causes the purple color of the potassium permanganate solution to fade as the manganese ions are formed. The resulting solution may turn colorless or pink, depending on the concentration of the reactants.
