What else can I help you with?
Is powder alum soluble in kerosene?
No, powder alum is not soluble in kerosene. Alum, which is typically a hydrated double sulfate of aluminum and another metal, is soluble in water but does not dissolve in non-polar solvents like kerosene. Kerosene is a hydrocarbon solvent, and since alum is ionic, it does not interact favorably with kerosene.
Is alkali colourless?
yes i belive so best to double check!!
What happen if you add the copper sulphate to sodium hydroxide?
If you add copper sulfate to sodium hydroxide, a double displacement reaction will occur. The copper sulfate will react with the sodium hydroxide to form copper hydroxide, which is a blue solid, and sodium sulfate, which is a soluble compound. This reaction is often used in qualitative analysis to test for the presence of copper ions.
What is alumn?
An alumn is another name for an alum, a kind of salt used in the dyeing and tanning trade and in medicines, understood to be a double sulphate of potassium and aluminium, or any similar double sulphate.

Does ethene change from orange to colourless when it reacts with bromine water?
Yes, ethene reacts with bromine water to form a colourless solution. In the presence of ethene, the orange-brown color of bromine water disappears as bromine is consumed in the addition reaction with ethene to form a colourless compound.
What happens if you mix cooking oil with bromine water?
The bromine water turns from orange to colourless, as it is breaking the double bonds. When the oil becomes saturated, any more bromine water that is added will not turn colourless.
Barium chloride and sodium sulphate in water react to give insoluble barium sulphate and the solution of sodium chloride?
Yes, it is true. The equation of reaction is :- BaCl2 + Na2SO4 --------> 2NaCl(aq.) + BaSO4 where solution is of sodium chloride and Barium sulphate settles down at the bottom as precipitate
Why is the reaction between barium chloride and sodium sulphate also called presipitation reaction?
It is because the white precipitate of barium sulphate by the reaction of SO4(VALENCY -2) AND BA2.THE OTHER PRODUCTS FORMED IS SODIUM CHLORIDE WHICH remains in the solution. This is an example of double displacement reaction. NA2SO4(aq)+BACl2(aq) -- BASO4(S)+2NACl(aq)
Barium sulfate plus calcium chloride?
When barium sulfate is mixed with calcium chloride, a double displacement reaction occurs where barium chloride and calcium sulfate are formed. Barium chloride is soluble in water, while calcium sulfate is not, so a solid precipitate of calcium sulfate will form.
Who proposed double sulphate theory of lead acid accumulators?
The double sulfate theory of lead-acid batteries was proposed by Wilhelm Ostwald in the late 19th century. He proposed that during the discharge of lead-acid batteries, lead sulfate is converted into lead dioxide and sulfuric acid, while during charging, the reverse reaction occurs.
What happens when potassium iodide is mixed with copper sulphate?
In the laboratory, copper(I) Iodide is prepared by simply mixing an aqueous solutions of potassium iodide and a soluble copper(II) salt such copper sulphate. : :: Cu2+ + 2I− → CuI2 The CuI2 immediately decomposes to iodine and insoluble copper(I) iodide, releasing I2. : :: 2 CuI2 → 2 CuI + I2
