How do you prepare standard solution of potassium dichromate to compare icteric index of serum?
for preparing 0.1 normal solution of potassium permanganate you have to disssolve 3.16 g potssium permangnate in 1L water bt in alkaline or neutral medium reactions of potassium permanganate is different and Mn gains 3 electrons in redox reaction,so far alkaline medium redox titration equivalent wt of KMnO4 will be 158\3=52.6.so far,0.1 N KMnO4 in alkaline medium redox titration dissolve 5.26 g in 1L sol.
Uses of potassium permanganate?
Potassium metal is used in photoelectric cells. Potassium forms many compounds resembling corresponding sodium compounds, based on a valence of 1. A few of the element's most important compounds follow. Potassium bromide (KBr), a white solid formed by the reaction of potassium hydroxide and bromine, is used in photography, engraving, and lithography, and in medicine as a sedative. Potassium chromate (K2CrO4), a yellow crystalline solid, and potassium bichromate, or potassium dichromate (K2Cr2O7), a red crystalline solid, are powerful oxidizing agents used in matches and fireworks, in textile dyeing, and in leather tanning. Potassium iodide (KI), a white crystalline compound that is very soluble in water, is used in photography for preparing gelatin emulsions and in medicine for the treatment of rheumatism and overactivity of the thyroid gland. Potassium nitrate (KNO3), a white solid prepared by fractional crystallization of sodium nitrate and potassium chloride solutions, is used in matches, explosives, and fireworks, and in pickling meat. It occurs naturally as saltpeter. Potassium permanganate (KMnO4), a purple crystalline solid, is used as a disinfectant and germicide and as an oxidizing agent in many important chemical reactions. Potassium sulfate (K2SO4), a white crystalline solid, is an important potassium fertilizer and is also used in the preparation of potassium alum. Potassium hydrogen tartrate (KHC4H4O6), commonly known as cream of tartar, is a white solid used in baking powder and in medicine.
Why 85ml of HCl is taken for preparing normal solution?
85 mL of (concentrated, 38%) HCl solution contains 36.5 gram HCl, which dissolved and diluted in up to 1.0 Liter gives you an 1.0 molar solution.

What are the uses of concentrated sulphuric acid?
Concentrated sulphuric acid is a cheaper chemical reagent when compared to many others. Although there are many uses of this acid in various industries. Some of them are shown below.Manufacturing of superphosphate fertilizers and other types. (This is the most important usage of concentrated sulphuric acid).Paint industry - In preparing pigments , as an example titanium dioxide can be taken.Industry of artificial fibre - Some of the example materials are rayon and plastic.Detergent industry - Alkyl or aryl sulphonates are often used as the active ingredient of detergent powder.Petroleum industry - Extracting alkenes.Steel industry - When preparing steel, sulphuric acid is used to remove the oxide layer which lies on the iron metal surface.Manufacture of various organic and inorganic compounds such as drugs, paints, metallic sulphates etc.

What major mistake did the Allies make in preparing to defend against Germany's attack on France?
The major mistake that the Allies made in preparing for Germany's attack in 1940 was their assumption that the Ardennes Forest was impassable. They concentrated their forces to the north and south of it. When Germany attacked through the Ardennes, they encountered weak resistance, which allowed them to complete their plan of encircling the allied armies.
How is hypokalemia diagnosed?
Potassium ion levels are measured in the blood serum. If the levels fall below the normal range, the patient is diagonised with hypokalemia.
Which nutrient ingredients are required when preparing a culture medium for bacteria growth?
The key nutrient ingredients required when preparing a culture medium for bacteria growth are a carbon source (like glucose), a nitrogen source (like peptone or ammonium salts), minerals (such as magnesium and potassium), vitamins, and water. Additional ingredients, such as agar for solidification and pH indicators, may also be included depending on the specific needs of the bacteria being cultured.
How many parsnips for 100 people?
You would need approximately 25 pounds of parsnips to serve 100 people assuming each person is served a 4oz portion. It's advisable to account for variations in serving sizes and preferences when preparing the parsnips.
