Dipotassium phosphate (K2HPO4) - also phosphoric acid, dipotassium salt; dipotassium hydrogen orthophosphate; potassium phosphate, dibasic - is a highly water-soluble salt which is often used as a fertilizer, food additive and buffering agent. It is a common source of phosphorus and potassium. The pH of a dipotassium phosphate solution is almost neutral. It is formed by the stoichiometric neutralization of phosphoric acid with potassium hydroxide: H3PO4 + 2 KOH → K2HPO4 + 2 H2O It reacts with phosphoric acid to generate monopotassium phosphate: K2HPO4 + H3PO4 → 2 KH2PO4
One common acid used in fertilizers is sulfuric acid. It is used to lower the pH of the soil and make certain nutrients more available to plants.
To make a 1M KH2PO4 buffer solution, dissolve 136.09 grams of KH2PO4 in enough water to make a final volume of 1 liter. Always ensure that the pH of the solution is adjusted to your desired value using an appropriate acid or base, such as NaOH or HCl.
KH2PO4, also known as potassium dihydrogen phosphate, can act as both an acid and a base depending on the circumstances. It can donate a proton (H+) and act as an acid in a reaction, or it can accept a proton and behave as a base.
The pH of a KH2PO4 solution will depend on its concentration. However, since KH2PO4 is a weak acid, a typical solution will have a slightly acidic pH, around 5.5 to 6.5.

The chemical formula for potassium hydrogen phosphate isK2HPO4(Another salt is potassium dihydrogen phosphate: KH2PO4)

No, potassium dihydrogen phosphate and potassium phosphate monobasic are not the same compound. They have different chemical formulas and structures. Potassium dihydrogen phosphate has the chemical formula KH2PO4, while potassium phosphate monobasic has the formula K2HPO4.
The pH of a KH2PO4 solution will depend on its concentration. However, since KH2PO4 is a weak acid, a typical solution will have a slightly acidic pH, around 5.5 to 6.5.
KH2PO4 is slightly acidic in solution. It is a salt of a weak acid (phosphoric acid) and a strong base (potassium hydroxide), which means that it will slightly increase the acidity of a solution when dissolved in water.
The chemical equation for the reaction between sulfuric acid (H2SO4) and potassium dihydrogen phosphate (KH2PO4) is: H2SO4 + KH2PO4 -> K2SO4 + H3PO4
K2HPO4 is a salt derived from a weak acid (H3PO4) and a strong base (KOH). It behaves as a basic salt because the conjugate base of the weak acid (HPO4^2-) can accept protons in a reaction.
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.
