How many grams of crystals will b formed if a saturdayed potassium nitrate solution is cooled from 60 to 30?
The amount of crystals formed will depend on how much potassium nitrate was dissolved in the solution to begin with. As the solution cools from 60°C to 30°C, potassium nitrate will begin to crystallize out of the solution. The exact amount of crystals can be determined by calculating the solubility of potassium nitrate at 30°C and comparing it to the initial concentration in the solution.
Explain the functions of solution A and solution B?
The function of solution A and B is to have a color change to cherry red if nitrites are present in the product.
What is the chemical composition of Dragendorff's reagent?
Dragendorff's reagent typically consists of a mixture of potassium bismuth iodide (KBl3) and bismuth triiodide (BiI3) dissolved in a solution of acetic acid. This reagent is commonly used in chemistry for detecting alkaloids and alkaline earth metals.
Why does magnesium ribbon not react with sodium sulphate solution?
as a displacement reaction has to occur when the metal is higher in the reactivity series thatn the metal in the salt. With your question this is not the case as sodium is higher than magnesium and so nothing will take effect.
Two solutions A and B have a pH of 6 and 8 what is their nature?
Solution A is weekly acid Solution B is weekly basic

How do you prepare Dragendorff?
Solution A: Bismuth nitrate (0.17g) in AcOH (2mL) and H2O (8mL) Solution B: KI (4g) in AcOH (10mL) and H2O (20mL) Mix Solns. A and B and dilute to 100mL with H2O.
Explain the functions of solution A and solution B?
The function of solution A and B is to have a color change to cherry red if nitrites are present in the product.
If solution A has more solute and less water than solution B then solution A is what to solution B?
Solution A is highly concentrated than solution B.
