29 de mai. de 2024 · Complete answer: The Henderson–Hasselbalch equation is generally used to determine the pH of a buffer solution and finding out the equilibrium pH in the acid-base reaction. According to the Henderson-Hasselbach equation, pH of buffer solution is calculated using the following formula: pH = pKa + log [salt] [acid]

Há 5 dias · Step by step answer: Let us first look at the buffer solution. Buffer Solution: So buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Its pH changes very little when a small amount of strong base or acid is added to it. So according to the above definition analyzing all the options.
20 de mai. de 2024 · Hence with increasing dilution of the solution, solute j is increasingly stabilised, μj(aq; T; p) decreasing to ‘ − ∞ ’ in an infinite amount of solvent Using the Gibbs-Helmholtz Equation, equation (a) yields equation (f). − Hj(aq; T; p) / T2 = − H0 j(aq; T; p) / T2 + R (∂ln(γj) / ∂T)p. Hj(aq; T; p) is the partial molar ...
Há 4 dias · Approach Solution - 1. The limiting molar conductivity that is denoted by Λ°. It is the measure of the conductivity of the solution that contains one mole of an electrolyte that is dissolved in the solution. For the question, the limiting molar conductivity of NH4OH is given by: Λ° (NH4Cl) +Λ° ( NaOH) - Λ° (NaCl)
