Volumetric Flask
The volumetric flask is the best.
To prepare a 50mm glucose solution, you would need to dissolve 9g of glucose in enough water to make 100mL of solution. This would give you a solution with a concentration of 50mm (millimolar).
it is device that used to measurethe strength of brine solution
To prepare a chitosan solution, dissolve chitosan powder in an acidic solution (such as acetic acid or hydrochloric acid) with stirring. Adjust the pH as needed and filter the solution to remove any undissolved particles. The concentration of the chitosan solution can be adjusted by varying the amount of chitosan powder used.
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
The best instrument to use to prepare a solution depends on the accuracy and volume of the solution needed. Common instruments include pipettes for precise measurements and volumetric flasks for accurate volume measurements. Additionally, a balance may be used to weigh out solid solutes for solution preparation.
The volumetric flask is the best.
To prepare a 0.01N KBr solution, dissolve 0.74g of KBr in 1 liter of water. This will give you a solution with a molarity of 0.01N for KBr.
See the two Related Questions to the left for the answer.The first is how to prepare a solution starting with a solid substance (and dissolving it). The second question is how to prepare a solution by diluting another solution.
To prepare a buffer solution which may be acidic. Titrate ethanoic acid (weak acid) with sodium ethanoate(salt).
To prepare a 0.5M glutaraldehyde solution, you would need to dilute a concentrated glutaraldehyde stock solution with the appropriate volume of water or buffer solution. Calculate the volume of stock solution needed based on the desired final volume and concentration, then dilute with the solvent. Finally, mix the solution thoroughly to ensure uniform distribution. Remember to follow safety protocols when working with glutaraldehyde, as it is a hazardous chemical.
There are a few different ways to do this. However, it doesn't mean that it is the best way for you either.
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.
Yes, by décreasing the volume tenfold.
To prepare a 50mm glucose solution, you would need to dissolve 9g of glucose in enough water to make 100mL of solution. This would give you a solution with a concentration of 50mm (millimolar).
To prepare a 2 ppm solution of nickel nitrate, you would dissolve 2 grams of nickel nitrate in enough water to make 1 liter of solution. This will result in a solution where there are 2 parts of nickel nitrate for every 1 million parts of water.
To prepare a 0.2 ppm solution from a 1000 ppm solution, you would need to dilute the 1000 ppm solution by adding 5000 parts of solvent for every 1 part of the 1000 ppm solution. This means mixing 1 part of the 1000 ppm solution with 5000 parts of solvent to achieve a 0.2 ppm concentration.
