WebWhat’s the PH of this question. Transcribed Image Text: 1) Calculate the pH of a solution prepared by dissolving 2.05 g of sodium acetate, CH3COONa, in 85.0 mL of 0.10 Macetic acid, CH3COOH (aq). Assume the volume change upon dissolving the sodium acetate is negligible. K₂ of CH3COOH is 1.75 x 10-5. pH =. WebThe net energy is calculated by taking the difference between the lattice energy and the heat of hydration (the energy required to hydrate the solution). This difference indicates whether or not the reaction is exothermic (of it is negative) or endothermic (if it is positive). Sodium acetate is not hydrated at all, so more energy is required to hydrate it. cheap conchos
