Using the equations (discussed above) showing the relationship between [acid], [conjugate base] and [buffer concentration], mathematically show the negligible change in pH even when 2µL of 10M HCl is added to 100 ml of 50 mM Phosphate buffer at pH 6.9. To address this problem, the following steps will be needed: (i) You will have to calculate the pH of the buffer after adding the 2µL of 10M HCl (ii) To do this, calculate the new concentration of [acid] and...

70.0 mL base with 2.00 M molarity is added to 80.0 mL Oxalic acid with 1.80 M molarity. The initial temperature is 20.0 °C and specific heat capacity is assumed to be the same as water (4.184 J/ g °C). Once the reaction reached thermal equilibrium, the temperature became 32.72°C. Find the enthalpy of neutralization for base.
