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?
There are 7 atoms in K2SO4: 2 potassium atoms (K), 1 sulfur atom (S), and 4 oxygen atoms (O).
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 (K). In this compound, the potassium ion (K+) has a charge of +1, and the X element has a charge of +7 to balance the overall charge of the compound. The compound is likely potassium perchlorate, where the X element is chlorine (Cl), which has a charge of -1 in this compound.

The acid in the hot solution helps to increase the reactivity of the potassium permanganate.
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?
No, potassium manganate (K2MnO4) and potassium permanganate (KMnO4) are not the same compound. Potassium manganate has a +6 oxidation state for manganese, while potassium permanganate has a +7 oxidation state. Additionally, they have different chemical properties and uses.
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?
The product of the reaction between ethene and acidified potassium manganate VII is ethane-1,2-diol (ethylene glycol). This reaction is a syn-diol formation where two hydroxyl groups are attached to the same carbon atom in the ethene molecule.
What is the formula for acidified potassium dichromate?
The formula for acidified potassium dichromate is K2Cr2O7. It is a chemical compound consisting of potassium ions and dichromate ions which is commonly used as an oxidizing agent in organic chemistry reactions.
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.
Chemical formula for potassium and chlorine?
The chemical formula for potassium is K and for chlorine is Cl. When combined, they form potassium chloride with the formula KCl.
How many atoms in K2SO4?
There are 7 atoms in K2SO4: 2 potassium atoms (K), 1 sulfur atom (S), and 4 oxygen atoms (O).
