Calculate the standard enthalpy change for the reaction between 50.0 mL of 0.200 M HCl(aq) and 50.0 mL of 0.300 M NaOH(aq) at 25°C. The heat capacity of the calorimeter is 9.60 J/°C and the temperature change observed is 4.00°C. Also, assume that the density of both solutions is 1.00 g/mL and that the heat capacity and density of the final solution are the same as that of water.

A student has a solution of acetic acid (CH3COOH) with a concentration of 0.1 M and wants to calculate the effect of adding sodium acetate (NaCH3COO) with a concentration of 0.05 M on the equilibrium position of the reaction CH3COOH + H2O ↔ CH3COO- + H3O+. Calculate the new equilibrium concentrations of all species and explain the effect of the added common ion on the equilibrium position.
