Alum (Aluminum Sulfate) is/was used to cause particles in water (mud) to coagulate and settle to the bottom to obtain clear water off the top. That is, it is used to make muddy or cloudy water clear as a first step in turning river water into drinking water. Nowadays, polymers are used instead. Some say that Alum causes alzeimers (1970's) but if that is true, the information was successfully hushed while most of America drank water treated with alum for decades.
Lime is used to adjust the ph that is lowered by the alum. There is also a process using lime that actually removes hardness (calcium and magnesium) from drinking water obtained from limestone aquifers. This process is called Lime Soda Softening.

What is difference between feeric alum and non ferric alum?
Ferric alum contains iron, which gives it a yellow color, while non-ferric alum does not contain iron and is typically colorless. Ferric alum is commonly used in water purification and wastewater treatment processes, while non-ferric alum is used in industries like paper manufacturing and tanning.
Can you use calcium chloride in place of alum?
No, calcium chloride cannot be used in place of alum. They have different chemical properties and functions. Alum is commonly used in water treatment and as a mordant in dyeing, while calcium chloride is used for de-icing roads, in food preservation, and as a drying agent.
How can you separate a mixture of sand and alum?
If the mixture is passed quickly through a magnetic field, eddy currents are formed in the moving metal and cause a small electric field that pulls the aluminum into the magnet. The problem is that once the metal stops moving, it ceases being attracted and then falls down.
How would you test for potassium and sulfate ions in the alum?
To test for potassium ions, you can use a flame test by heating a sample of the alum on a looped wire in a Bunsen burner flame; potassium ions produce a lilac flame color. For sulfate ions, you can add a few drops of barium chloride solution to a solution of the alum; a white precipitate (barium sulfate) forms if sulfate ions are present.
Making of ferric alum?
Ferric alum is made by dissolving bauxite in sulfuric acid to obtain aluminum sulfate. Ferric oxide is then added to this solution to form ferric alum. The solution is then set aside for the crystals of ferric alum to form through a process called crystallization.
What is the process of adding alum to water called?
alum water (AlH20)
How much alum do you use in swimming pool water?
Alum in a swimming pool clarifies the water. Alum is used in water treatment plants for this purpose and is in the drinking water suply in trace amounts. Alum in a swimming pool clarifies the water. Alum is used in water treatment plants for this purpose and is in the drinking water suply in trace amounts. Alum is a floculant it is cast over the surface of water, as it sinks to the bottom it attaches its self to impurity's in the water eventualy one will note that all of the water has cleared up except for a layer at the bottom, this is normally disposed of leaving clean uncontaminated water.
What can stop the effect of sodium fluoride poisoning?
Alum treatment of water
What alum is used to treat water?
Aluminum Sulphate acts as a coagulate in water treatment
What alum are used for?
it is used for water treatment in industries and water cleanong in domestic uses
What is alum used for?
Alum is used in vaccines as an adjuvant. Alum is commonly used as a coagulant in water treatment. And its used for domestics water.
What is difference between feeric alum and non ferric alum?
Ferric alum contains iron, which gives it a yellow color, while non-ferric alum does not contain iron and is typically colorless. Ferric alum is commonly used in water purification and wastewater treatment processes, while non-ferric alum is used in industries like paper manufacturing and tanning.
Why is coagulation important in water treatment processes?
Coagulation is important in water treatment processes because it helps to remove impurities and particles from the water. By adding coagulants, such as alum or ferric chloride, to the water, these substances bind together with the impurities, forming larger particles that can be easily removed through filtration. This process helps to improve water quality and make it safe for consumption.
What is the function of alum in the treatment of water?
Solutions containing alum may be used to treatcloth, wood and paper ... Alum is used to clarify water by neutralizing the electrical double layer .... the calculated quantity of potassium sulfate, well agitated, and the alum is thrown
Does alum react with crude oil?
Alum typically does not react with crude oil. Alum is commonly used as a coagulant in water treatment processes to remove impurities, but it is not designed to react with petroleum-based substances like crude oil.
How is shaving alum made?
Shaving alum, also known as potassium alum, is typically made by dissolving aluminum sulfate in water and adding potassium sulfate to form double salts. The solution is then cooled and the resulting crystals are harvested and purified to produce shaving alum in its solid form.
What do you think was the purpose of putting alum into tha plant indicator?
Indicators can also be prepared from plants. The red, purple, and blue colors of most plants indicate the presence of an organic substance called anthocyanins. The purpose of putting alum is to retrieve the anthocyanins present in plants.
