Question
1. a) Write a net ionic equation for the neutralization of NaOH by a component of a buffer buffer = .5M HC2H3O2 / .5M NaC2H3O2 (mixture of both) b) [then] Write a net ionic equaiton for the neutralization of HCL by a component of the buffer (addition of 3M HCl) c) compare your results in 2. and 3. Are the base-neutralizing capacity and the acid-neutralizing capacity of the buffer similar? Explain why or why not.
2. a) Write a net ionic equation for the neutralization of NaOH (3M) buffer = .5M HC2H3O2 b) compare your results in 2 (above). and 5. Are the base-neutralizing capacities of bufer and acid comparable? Explain why or why not
3. a)Write a net ionic equation for the neutralization of HCL (3M) buffer = .5M NaC2H3O2 b) compare your results in 3. and 6. Are the acid-neutralizing capacities of buffer and salt comparable? Explain why or why not.
Explanation / Answer
1) The net ionic equation will be
NaOH + CH3COOH ---> CH3COO-Na+ + H2O
Net ionic equation
H+ + OH- --> H2O
For HCl
Net ionic equation will be
CH3COO-Na+ + HCl ---> CH3COOH + Na+ + Cl-
CH3COO- + H+ ---> CH3COOH
In all the cases the the base or acid neutralizing capacities of buffer will be same.
