2. Write the chemical equations for the neutralization reactions that occurred when HCL and NaOH were added to the buffer solution.

HCI(aq)+CH3COONa(s) > CH3COOH(aq)+NaCl(s)

NaOH(aq)+CH3COOH(aq) > CH3COONa(s)+H2O(l)

Explanation:

A buffer is a solution that resists changes in acidity or alkalinity. A buffer is able to neutralize a little amount of acid or base thereby maintaining the pH of the system at a steady value.

A buffer may be an aqueous solution of a weak acid and its conjugate base or a weak base and its conjugate acid.

The equations for the neutralizations that occurred upon addition of HCl or NaOH are;

HCI(aq)+CH3COONa(s) > CH3COOH(aq)+NaCl(s)

NaOH(aq)+CH3COOH(aq) > CH3COONa(s)+H2O(l)

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
