Potassium dihydrogen phosphate is used in Drabkin's solution to act as a buffer, maintaining the pH of the solution around 7.4. This helps stabilize the hemoglobin and prevent its oxidation during the hemoglobin assay or blood cell counts.
To prepare 20 mM potassium dihydrogen phosphate buffer with only dihydrogen phosphate, you can dissolve an appropriate amount of potassium dihydrogen phosphate in water to achieve the desired concentration of 20 mM. Since you are starting with only dihydrogen phosphate, you would need to adjust the pH of the solution by adding a strong base like sodium hydroxide until the desired pH (usually around 6.8) is reached.
Dibasic potassium phosphate buffer is a solution commonly used in laboratories to control the pH of a reaction or a sample. It consists of a mixture of potassium dihydrogen phosphate (KH2PO4) and dipotassium hydrogen phosphate (K2HPO4) in specific ratios to maintain a stable pH. This buffer is especially useful in biochemical and molecular biology experiments.
Yes, KH2PO4 (potassium dihydrogen phosphate) is an acid because it can donate a hydrogen ion in solution. K2HPO4 (potassium hydrogen phosphate) is a salt formed by the partial neutralization of an acid and a base, making it neutral.
The amount of potassium phosphate in the solution is 1.27 M * 0.343 L = 0.43561 moles.The chemical formula of potassium phosphate is K3PO4, so there is three times as many moles of potassium as there are moles of potassium phoshate in the molecule:0.43561 * 3 = 1.30683Answer: 1.31 moles
To prepare a 0.01M solution of sodium dihydrogen phosphate monobasic, you would first need to calculate the amount of the chemical needed based on its molar mass. Then, dissolve this amount of sodium dihydrogen phosphate monobasic in a specific volume of water to achieve a final concentration of 0.01M. Finally, make up the volume with water and ensure complete dissolution to obtain the desired solution.

Potassium Dihydrogen Phosphate has a molecular formula of KH2PO4, while Dipotassium hydrogen phosphate has a molecular formula of K2HPO4. The addition hydrogen makes the potassium DIhydrogen more acidic, as pH is a measure of the H+ ions dissolved in a solution.
The dihydrogen phosphate ion - (H2PO4)-is an anion.
For the preparation of a solution with the pH=7,00:Add 29,1 mL sodium hydroxide solution 0,1 M to 50 mL potassium dihydrogen phosphate solution 0,1 M.

The reaction between barium nitrate (Ba(NO3)2) and potassium phosphate (K3PO4) will form barium phosphate (Ba3(PO4)2) and potassium nitrate (KNO3). The ions left in solution will be potassium (K+) and nitrate (NO3-) ions from the potassium nitrate. The barium phosphate will precipitate out of solution.

Yes, potassium phosphate is water soluble. It dissolves readily in water, forming an aqueous solution.
When ammonium nitrate solution is mixed with aqueous potassium phosphate, a precipitate of ammonium phosphate forms due to a double displacement reaction. Ammonium phosphate is insoluble in water and therefore will appear as a solid precipitate in the solution.
