How do you we prepare cresol with soap solution?
cresol is prepared with soap solution as it is more soluble in the soap solution than water . moreover soap solution enhances its detergent and disinfectant properties.
Is the parent isotope always radioactive In a nuclear equation?
No, the parent in the nuclear equation is not always radioactive. For example, the following reaction shows a neutron capture by 23Na, which is not radioactive. 1123Na + 01n --> 1124Na where 01n is a neutron.
Prepare a working solution from a stock solution?
it is very easy to prepare working solution from a stock solution we use the formula for this purpose which is: C1V1 = C2V2 C1 is the concentration of the stock solution V1 required volume from the stock solution C2 concentration of the working solution V2 volume of the working solution
How do you prepare polyethylene glycol solution?
PEG
How would you prepare tetracycline stock solution?
10 mg/ml stock solution
What mass of na2s2o3 5h2o is needed to prepare 500.00 ml of 0.1000 m na2s2o3?
Mol.Wt =248.17Molarity =( Wt/ Mol.Wt ) /No:of litres of solution0.1 =( Wt / 248.17) / 0.5Wt =0.1 *0.5*248.17Wt = 12.4085g in 500ml of solution.
What is a hypo solution?
A Hypo Solution is used in iodometric titrations, its is basically sodiumthiosulphate (Na2S2O3)
How would you prepare 1L of 000100 M Na2S2O3 starting with solid Na2S2O3 The numbers in Na2S2O3 are subscripts.?
first we calculate the molecular weight M.W=158.11 mass of Na2S2O3=M.W*concentration*volume(in litter) for a concentration of 0.001 mass of Na2S2O3=158.11*0.001*1=0.15811 g so we use this mass and continue the volume to be 1 L
Why do you use 25 grams to prepare 0.1N sodium thiosulfate solution?
You do not need especially 25 grams to prepare 1.0 Liter 0.1N Na2S2O3-solution.It depends what substance is used: Na2S2O3 orNa2S2O3•5H2O (more common, called hypo).Molar masses are different, 158.11 g/mol for Na2S2O3 or(158.1 g/mol + 5*18.02 = ) 248.2 g/mol for Na2S2O3•5H2O respectively.To get the 0.10 N solution you'll need 15.8 gram or 24.8 gram respectively, dissolve it togather with 1 gram of disodium carbonate, and add up to 1.0 Liter (freshly boiled) water, let stand overnight and filter on fine grade paper.
How would the appearance of the solution change for each kinetic trial if the Na2S2O3 solution were omitted from the experiment?
It would change the Voltage.
What is the structure of NA2S2O3?
stanaderised of Na2S2O3 .
What is hypo solution used in chemistry for iodometric titration?
hypo solution used in iodometric titration is sodiumthiosulphate. Its N\10 normality of Na2S2O3.
Why water cannot be used to prepare sodium thiosulphate solution?
One should use freshly boiled pure water to prevent oxidation by otherwise present oxygen. After complete solvation of the 'hypo' (more familiar known as the pentahydrate, Na2S2O3•5H2O) the solution should be filtered to after standing overnight to remove sparse sulfur sedimentation.
How do you prepare 05M glutaraldehyde?
how to prepare .05M glutaraldhyde solution molecular weight is 100.12
How can a solution of ammonia be used to prepare ammonia sulphate?
A solution of ammonia can be used to prepare ammoniumsulfate by reacting it with a solution of sulfuric acid to produce a solution of ammonium sulfate, which can be dried if desired to prepare solid ammonium sulfate.
How do you prepare 2 ppm solution of nickel nitrate?
how to prepare 1000 ppm solution of nickel carbonate
What are the oxidation numbers for the elements in Na2S2O3?
