To prepare 0.01 M sodium phosphate solution, dissolve the calculated amount of sodium phosphate dibasic (Na2HPO4) in distilled water. Use a balance to measure the required mass based on the molecular weight of Na2HPO4 and make up the volume to the desired concentration of 0.01 M. Always wear appropriate safety gear and handle chemicals carefully.

How do you make a sodium phosphate buffer solution of pH 6.8?
To prepare a sodium phosphate buffer solution of pH 6.8, mix the appropriate amounts of monosodium phosphate (NaH2PO4) and disodium phosphate (Na2HPO4) in water. Adjust the ratio of the two components to achieve the desired pH using a pH meter or a buffer calculator.
0.2 M sodium phosphate buffer pH 7.0?
A 0.2 M sodium phosphate buffer at pH 7.0 contains a mixture of sodium dihydrogen phosphate (monobasic) and disodium hydrogen phosphate (dibasic) dissolved in water. This buffer system can help in maintaining a stable pH around 7.0 when small amounts of acids or bases are added to the solution.
How do you prepare 0.02 m phosphate buffer?
To prepare a 0.02 M phosphate buffer, you would need to mix suitable amounts of a monobasic potassium phosphate and a dibasic potassium phosphate solution with water to achieve the desired concentration. Calculate the required volumes of each solution based on their respective concentrations and molar masses. Finally, adjust the pH as needed with the addition of acid or base.
How you prepare 10 mM phosphate buffer from 0.5 M phosphate buffer?
To prepare a 10 mM phosphate buffer from a 0.5 M phosphate buffer, you would need to dilute the 0.5 M buffer by a factor of 50. Calculate the volume of the 0.5 M buffer needed and add water to make up the total volume needed. For example, to make 100 mL of 0.5 M phosphate buffer into 10 mM, you would take 2 mL of the 0.5 M buffer and dilute it to 100 mL with water.
What is sodium phosphate's pH level?
Sodium phosphate solutions can have varying pH levels depending on their concentration. Generally, sodium phosphates are basic in nature and tend to raise the pH of a solution. For example, sodium phosphate dibasic has a pH of around 9-9.5 in a 0.1 M solution.

How do you prepare sodium citrate 1.25 m?
To prepare a 1.25 M solution of sodium citrate, dissolve 294.1 grams of sodium citrate dihydrate powder in 1 liter of water. Mix well until the powder is completely dissolved. Adjust the volume if necessary to reach exactly 1 liter.
How do you prepare 0.1 M sodium acetate?
To prepare 0.1 M sodium acetate, you will need to weigh out the appropriate amount of sodium acetate trihydrate or anhydrous sodium acetate based on the molarity you desire. Dissolve this in a specific volume of water, typically in a volumetric flask, and then make up the final volume to the desired concentration. Stir well to ensure complete dissolution.
How do you prepare 0.5 M phosphate buffer pH 7.0?
To prepare 0.5 M phosphate buffer pH 7.0, dissolve the appropriate amounts of monobasic potassium phosphate and dibasic potassium phosphate in water. Adjust the pH using either dilute HCl or NaOH, while continuously checking with a pH meter until pH 7.0 is reached. Dilute to the desired final volume with water if needed and ensure that the final pH is within the acceptable range.
