What is the basicity of H3PO4

The Role of Sodium Hexametaphosphate in Coatings

Due to the addition of sodium silicate and other alkaline substances the alkaline environment with PH value of 10-10 5 was prepared that is the concentration of OH-ion in the coating is high and the reaction proceeds to the right which is helpful for the further decomposition of H3PO4 and the conversion of sodium hexametaphosphate to orthophosphate At this time the phosphate will

Introduction to Inorganic Chemistry/Acid

The acidity and basicity of non-aqueous solvents is difficult to quantify precisely but one good relative measure is the Hammett acidity function H o H o is defined analogously to pH according to the Henderson-Hasselbach equation: H o = pK a + log([base]/[conjugate acid]) For non-aqueous solvents or for acidic or basic compounds in dissolved in solvents that do not themselves dissociate H

Classification of Acids

Hello students we've already learned about acids in our previous lessons In this lesson we shall see how acids are classified We know that acids are substances which are sour to taste and you also know that acids are called acids because they produce H+ ions in

STRENGTH OF NUCLEOPHILES (NUCLEOPHILICITY)

Basicity deals with interaction with H+ while nucleophilicity is broader and also deals with interaction with other atoms especially but not only C atom Polarizability of Nucleophiles: A polarizable nucleophile e g I- is large and soft ('teddy bear-like') because its valence (donor) electrons are far from the nucleus (in the 5th period) The electron cloud is readily distorted

Strength of Bases

The base dissociation constant K bE measures a base's basicity or strength K b is related to the acid dissociation constant K a by the simple relationship pK a + pK b = 14 where pK b and pK a are the negative logarithms of K b and K a respectively K b and K a are also related through the ion constant for water K w by the relationship [latex]text{K}_text{W}=text{K}_text{a}times
