Kaolin is a white clay. It is used as pigment for coating paper and as a filler in the body of the paper, in the manufacture of porcelain and other fine china.It is also used paints, refractories, plastics, sanitary wares, fiberglass, adhesives, ceramics, and rubber products.

CLAY- Earth material, chiefly made up of Al2 O3.2SiO2.2H2O,(Aluminium oxide/silicon dioxide/hydrogen oxide ?) forming a paste when wet but turning very hard under the operation of heat.\nSAND- Loose material formed of small but clearly separate round grains, chiefly of QUARTZ, from about 0.1 to 1 mm, across, produced by the rubbing away of solid stone, and put down in stretches by water or formed into masses by wind.

Bentonite is a type of clay that has some specific features that make it useful in many different industries.  Its structure is such that it forms "platelets" of a very small particle size, which provide an enormous amount of surface area.  This surface is very chemically active and highly receptive to water.  When water permeates a Bentonite clay, the individual platelets chemically bond to one another and swell as a mass, forming a virtually water-tight seal.  This is why Bentonite clays are often used to waterproof foundation walls, and also as a sort of grout that can be pumped or sprayed into/around structures that will be exposed to water (i.e. pilings, pond linings, retention basins, etc) in order to prevent water intrusion.  It can also be mixed with soil to create a harder, more impervious compacted soil which provides a better base for construction. Bentonite clays are also widely used in paints and other coatings as viscosity modifiers, since the chemical/mechanical activity of wetted and dispersed Bentonites is to "swell" and thereby provide a thicker viscosity to otherwise "thin" materials.  It's frequently a component of fingernail lacquers, which require a fairly high viscosity for ease of application.

Potassium permanganate is used as an oxidizing agent in many different kinds of chemical reactions in a laboratory and in industry.[1] It is also used as a disinfectant and in deodorizers. It is used to treat some parasitic diseases of fish, and used in treatment of drinking water, as well as an antidote in phosphorus poisoning. In Africa many people have used it to soak vegetables and lettuce to neutralize any bacteria that may be present. It can be used as a reagent for the synthesis of many different kinds of chemical compounds. For example, a dilute solution of KMnO4 can convert an organic compound with a carbon-carbon double bond into a diol (glycol) compound. Stronger permanganate solutions can oxidize a methyl group on an aromatic ring to a carboxyl group. In analytical chemistry, a standardized aqueous solution of KMnO4 is sometimes used as an oxidizing titrant for redox titrations due to its deep purple color.\n\nDeep purple-colored permanganate can be reduced to the faintly pink Mn+2 cation in an acidic solution, where Mn is in a +2 oxidation state. In an neutral solution, permanganate is only reduced to MnO2, a brown precipitate in which Mn is in a +4 oxidation state. In an alkaline solution, it is reduced to +6 oxidation state, giving K2MnO4.\n\nKMnO4 can be used in an oxidative reaction with pseudoephedrine hydrochloride to produce methcathinone, a Schedule I drug in the United States. Consequently the DEA has restricted its use and sale by classifying it as a List I controlled precursor. Potassium permanganate is listed as a Table I precursor under the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances(Red list).\n\nDilute solutions are used as a mouthwash (0.25%), disinfectant for the hands (about 1%) and treatment for mild pompholyx dermatitis or fungal infections of the hands or feet.\n\nIn aqueous solution was used as together with T-Stoff (i.e. 80 % hydrogen peroxide) as propellant for the rocket plane Messerschmitt Me 163. In this usage, it is known as Z-Stoff. This combination of propellants is still used in torpedoes.\n\nIt is used as a reagent to determine the Kappa number of wood pulp

The last answer is correct.\n\nLimestone acts to raise the pH of the soil. It is basic which means it is on the base end of the pH scale.\n\nThe reason limestone is a base is b/c of its composition. Limestone is calcium carbonate or CaCO3. The calcium is the base.\n\nIf you are interested in learning more about soil pH & other factors affecting soil, check out the link to the US Dept. of Agriculture.

ashes are basic. they can be helpful in reducing acidity levels in soil they are added to.

it is used to expell worms.\nbe careful not do use for long periods.

It is also found in the nut shell of cashew fruit. The Japanese have found a purpose for it.The oxidation and polymerization of urushiol in the tree's sap in the prescence of moisture allows it to form a hard lacquer, which is used to produce traditional Chinese and Japanese lacquerwares.

Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is non-reactive and non-irritating to body tissues. \n\nNotable Occurrences include Newry, Maine; San Diego Co., California; Colorado and Amelia, Virginia, USA; Renfrow County, Ontario, Canada; Madagascar; Sweden; Norway and Finland

Potassium - Nutritionists use this along with other vitamins and minerals to restore electrolyte balance in anorexic and bulimic patients.  (Just one example)\n\nPotassium chloride - Used by executioners who administer the death penalty by lethal injection.  A massive dose of this stops the heart.\n\nPotassium bicarbonate - Used to retard or put out oil well fires.\n\nPotassium hydroxide - Used as an ingredient in soap by soap manufacturers.\n\nPotassium nitrate - Used in the manufacture of fertilizer, matches (along with sulphur), and pyrotechnics.

There are many things that can be used including alum and ferric salts.  The best thing and the first thing I fix at a plant is to make sure the rest of the treatment system is working properly.  90% of the time, that alone will cause a decrease in the use of polymer and allows the use of a mineral salt treatment.  I do this work around the world.  The main use of the organic polymers for coagulation is simplicity of operation, cost, but mostly good salemanship.  You can cover up many bad operations by adding more polymer.\n\nGum will probably not work.  There are many things tried, but most of them do not overcome the good operations and cost issues.

Chalk sticks are manufactered from ground talc. Soapstone is the mined type of talc stone. Chalk is made to come apart easier on chalkboard so that the writing is much bolder. Soapstone is used for metal marking because it does not have that tendancy to mark as heavily and you can sharpen it to a point. Not to be confused with soapstone that is used for countertops which is acually related to granite and limestone

Hardness- materials such as a fingernail, penny, and ceramic tile can be used to determine the hardness of a mineral on the Mohs scale.

Potassium is a mineral that is found naturally in foods and is necessary for many normal functions of the body, especially beating of the heart. Potassium chloride is used to prevent or to treat a potassium deficiency.

Salt water. We use to clean rust off metal using kool-aid type mix because of the acid in it. Eats the rust away.
