The half-equivalence point of a titration occurs half way to the end point, where half of the analyte has reacted to form its conjugate, and the other half still remains unreacted. If 0.260 moles of a monoprotic weak acid (Ka = 6.2 × 10-5) is titrated with NaOH, what is the pH of the solution at the half-equivalence point?
a sample of Ringer's solution contains the following concentractions (mEq/L) of cations: Na 147, K 4 and Ca2 4. If CI- is the only anion in the solution,
An acid, HA, has the following thermodynamic values for its dissociation in water at 27 degrees celcius: ΔH=-8.0 kJ mol-1; ΔS=-70 J K -1 mol -1
what would be the chemical equation to this problem? In an investigation of the reaction between copper(II) ions, Cu2+, and hydrazine, N2H4, in alkaline conditions the following observations were made: 25 mL of a solution containing 25 g/L CuSO4.5..
