Are the twelve waters of hydration used to calculate the theoretical yield of the alum?
Yes, the twelve waters of hydration in the formula of alum, KAl(SO4)2·12H2O, are used to calculate the theoretical yield of alum. Each mole of alum contains twelve moles of water molecules, which must be accounted for when determining the expected mass of alum produced in a chemical reaction.
Does potash Alum Show sublimation or not?
Potash alum does not exhibit sublimation. Sublimation is the process where a substance transitions directly from a solid to a gas without passing through a liquid state. Potash alum undergoes decomposition when heated instead of sublimating.
What is the oxidation state of aluminium in potash alum.?
The oxidation state of aluminium in potash alum is 3
Why water's colour is green when use potash alum?
When potash alum is dissolved in water, it forms a complex with water molecules which can give a greenish tint to the water. This color is due to the interaction between the chemicals in potash alum and the light passing through the water, resulting in a green color being perceived.
What is the oxidation number of sulferin potash alum?
The sulfur in potash alum occurs in sulfate ions, which have the formula SO4-2. Since sulfur is less electronegative than oxygen, the oxygen has an oxidation number of -2; 4 atoms of oxygen give a total negative charge of -8, and the sulfur atom must have an oxidation number of +6 to match the -2 charge of the sulfate ion as a whole.
What is the common name for potash alum?
It's commonly called Alum

Project on preparation of potash alum from aluminium scrap observation table?
PREPARATION OF POTASH ALUM [(K2SO4.Al2(SO4)3.24(H2O)Aim:To prepare a pure sample of potash alum. [K2SO4.Al2(SO4)3.24H2O]Principle:Potash alum is prepared by dissolving an equi molar mixtureof aluminum sulphate and potassium sulphate in minimumamount of water containing a little amount of sulphuric acidand then subjecting the solution to crystallisation; octahedralcrystals of potash alum separate out.Apparatus required:Beaker (100 ml)TroughFunnelWire gauzeConical flask (100mL)Glass rodTripod standChemicals required:Aluminium sulphate: 10 gEthanol : 20 mLPotassium sulphate : 2.5 gDilute sulphuric acid : 1 mLProcedure:a.Take 20 ml of distilled water in a 100 ml beaker and heat itto about 40°c. Add about 1 ml of dilute sulphuric acid ,warm this and dissolve 10 g of aluminum sulphate addingsmall amounts at a time.b.Weigh 2.5 g of powdered potassium sulphate (given in thepacket) and add it to the above solution stir well.c. Heat the solution with constant stirring till potassiumsulphate dissolves completely on a water bath. Test thesolution at regular intervals of time far crystallisation point.d.Allow the solution to cool to room temperature.e.On cooling, white crystals of potash alum separate out.f. Decant the mother liquor carefully and shake gently with amixture of (1 cc alcohol + 1 cc water) to thecrystals mixture.g. Filter the crystals, dry these between the folds of a filterpaper and note the yield.Results:Weight of crystals obtained = ..................... gColour of the crystals = ......................The crystals of potash alum are octahedral in shape.Precautions:a. Cool the solution slowly to get good crystals. Avoid rapid cooling.b. Do not disturb the solution while cooling.

What is an alum stone?
An alum stone is a subsulphate of alumina and potash - also known as alunite.
Is alum the same thing as aluminum chlorohydrate?
Potash alum is another name for potassium alum. Alum is a class of molecular compounds, and included in the class is potassium alum. So, they are not the same thing, but yet very similar in that potash alum is a member of the alum class.
What are the effects of potash alum on human body?
Potash alum has the effect of a poison on the body. It has been linked to the incidence of Alzheimer's disease in people who have used it as a deodorant.
What is the pH potash alum?
A pH over 7.
How many ions present in potash alum?
6
Why do you take equimolar quantities of reacting compounds in the preparation of potash Alum?
Taking equimolar quantities ensures that all the reactants are used up completely in the reaction, leading to maximum yield of the desired product. It also helps in stoichiometric balance of the reaction and avoids wastage of any excess reactants.
What is the oxidation state of aluminium in potash alum.?
The oxidation state of aluminium in potash alum is 3
