How to determine i value chemistry

WebFrom the Henderson equation of acidic buffer, we can quickly determine the value of pKa from the pH. pH = pKa + log { [salt] / [Acid]} Let [salt] / [Acid] be equal to 10 then, pH = pKa + log 10 pH = pKa + 1 Let [salt] / [Acid] be equal to 1 / 10 then, pH = pKa + log 1 / 10 pH = pKa + log 1 – log 10 pH = pKa – 1 WebSep 15, 2024 · Subtract the smaller electronegativity from the larger one to find the difference. For example, if we're looking at the molecule HF, we would subtract the electronegativity of hydrogen (2.1) from fluorine (4.0). 4.0 - 2.1 = 1.9 2 If the difference is below about 0.5, the bond is nonpolar covalent. Here, the electrons are shared almost …

WebMar 13, 2024 · Working with such numbers is inconvenient, so to makes things easier, chemists have defined the pKa number as: pKa = -log Ka. According to this definition, the pKa value for hydrochloric acid is -log 10 7 = -7, while the pKa for ascorbic acid is -log (1.6 x 10 -12) = 11.80. As is evident, the smaller the pKa number, the stronger the acid. WebWe can use pKa to determine the Ka value. We know that pKa is equivalent to the negative logarithm of Ka. pKa = – logarithm [Ka] – pKa = logarithm [Ka] We can rewrite it as 10 – …

There are a few different ways of writing the formula to calculate the van’t Hoff factor. The most common equation is: i = moles of particles in solution / moles dissolved solute Because solutes don’t always fully dissociate in solution, there is another relation that is often used: i = 1 + α(n – 1) Here, α is the fraction of … See more For solutes that dissolve in water, the van’t Hoff factor is 1.
