To prepare an ethanolic solution, simply mix ethanol (commonly known as alcohol) with a solvent such as water. The ratio of ethanol to water will determine the concentration of the solution. Be sure to measure the quantities accurately and mix well to ensure homogeneity.
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 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
You could titrate equal volumes of 1M solution of NaOH and 1M solution of HCl to obtain 1M solution of NaCl.
To prepare cresol with soap solution, add cresol to a container of water, then add soap and mix gently. The soap will help to solubilize the cresol in water, forming a soap solution with cresol dissolved in it. It is important to follow proper safety precautions when handling cresol, as it can be irritating to the skin and eyes.
A perfume is a homogeneous mixture, generally an ethanolic solution.
Ethanolic KOH (potassium hydroxide dissolved in ethanol) is commonly used in organic chemistry for reactions such as deprotonation or elimination. The use of ethanol as a solvent can help improve the solubility of the potassium hydroxide and increase reaction rates. Additionally, the ethanolic solution can be easier to handle and work with compared to solid KOH.
Ethanolic NaOH is used instead of aqueous NaOH in titration to avoid side reactions with water and reduce error in the titration process. The absence of water in ethanolic NaOH helps maintain the concentration and stability of the solution, resulting in more accurate and precise titration results.
To prepare ethanolic KOH, you can dissolve potassium hydroxide (KOH) pellets in ethanol (ethyl alcohol). This process should be done slowly and carefully as it generates heat. It is important to wear appropriate safety gear, work in a fume hood, and follow proper lab protocols when handling these chemicals due to their caustic nature.
the conductance of ethanolic solutions depends upon the electrolyte(solute) present in it,but ethanol itself does not conduct any electricity.
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.
Ethanolic extraction will give 4hydroxyisoleucine.......
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.
