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.
No. Potash alum is specifically KAl(SO4)2 * 12H2O. Alum is any 1A metal with the Al(SO4)2 * 12H2O...so you can have Na, Rb and others.
True "alum" is considered the hydrated aluminium potassium sulfate.
Yes
Alum is the common name for aluminum potassium sulfate or aluminum sulfate.
Not at all. They are three completely different substances.
There is no difference in the meaning. The spelling aluminium is the international chemical term recommended by IUPAC (International Union of Pure and Applied Chemistry), in line with other names of elements (such as sodium, chromium, cadmium). In the US it is specifically spelled as aluminum. The pronunciation also varies. When it is spelled 'aluminium' it usually ends with the sounds 'nee-um'. When it is spelled 'aluminum' it is ends with the sound 'num'.
No, Al2O3 is aluminum oxide, it occurs naturally as the mineral corundum. Silica is silicon dioxide or SiO2, it occurs naturally as the mineral quartz.
No they are quite different Diamond - is a crystallized form of carbon Hardness 10 Topaz is a silicate mineral of aluminum and fluorine Hardness 8
yes. some people spell aluminium, other aluminum.
Alum is the common name for aluminum potassium sulfate or aluminum sulfate.
Sodium chloride is not alum salt.
Pretty much the same thing as happens when you tap aluminum with a hammer.
No. Ruby is the red variety of the mineral corundum or aluminum oxide (Al2O3). Beryl is a beryllium aluminum sillicate (Be3Al2Si3O18) and forms gemstones such as emerald and aquamarine.
No. They may be similar in some ways, but they definitely aren't the same thing. Among other differences, sodium silicate is soluble in water and aluminum silicate is not. (Both of them are actually metasilicates, not true silicates.)
No. Powdered aluminum has an ASBO.
Not at all. They are three completely different substances.
No. Potassium silicate is not the same as potassium aluminum silicate.
the answer is that you would need 1,000,000 to make it into the same amount of recycled aluminum.
"Made of" and "Made from" can mean the same thing. "That can is made from aluminum." "That can is made of aluminum." However, they can't be used the same in every situation. You can say: "That house is made of wood and made from workers." But you can't say: "That house is made of workers and made from wood."
aluminum. It is the same word for both English and french
