What is the difference between hot acidified potassium manganate 7 and potassium manganate 7?
acidified means that its chemical properties may be acidic in nature and since it is heated, it is more reactive..!
What happens when zinc is added to the acidified potassium permanganate?
3 Zn + Cr2O72- + 14 H+ → 3 Zn2+ + 2 Cr3+ + 7 H2O
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?
The purple colour is the Manganese in oxidation state '+7'. This oxidation state is reduced to '+2' ,which is pale green/colourless, when reacted with the alkene. Hence the change of colour.
What is the oxidation number assigned to manganese in KMnO4?
Manganese oxidation state = +7 So, it is also called Manganate(VII)
What is the difference between hot acidified potassium manganate 7 and potassium manganate 7?
acidified means that its chemical properties may be acidic in nature and since it is heated, it is more reactive..!
What is the product of the reaction between cyclohexane and acidified potassium manganate VII?
The product of the reaction between cyclohexene and hot acidified potassium manganate 7 will be cyclohexan-1,2-diol. Two hydroxy groups will bond at the site of the double bond.
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?
it is more soluble as hexane is non polar and potassium manganate is also non polar substances with like polarities mix so potassium manganate is more soluble in hexane
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 happens when zinc is added to the acidified potassium permanganate?
3 Zn + Cr2O72- + 14 H+ → 3 Zn2+ + 2 Cr3+ + 7 H2O
What is the formular of zinc manganate?
Zn(Mno4)7

He formula for potassium dichromate is KËÃCrËÃOËÈ How many grams of oxygen will be in 2 moles of potassium dichromate?
224 grams of Oxygen will be in 2 moles of Potassium dichromate.
What colour change will occur when potassium manganate VII reacts with iron II sulphate?
Mn(7+) is reduced to Mn(2+) going from purple to colourless/pale pink. The Fe(2+) ions are oxidised to Fe(3+) ions to complete the redox reaction.
