Problem- Consider the acetic acid buffer system with acetic acid, CH3COOH, and its salt sodium acetate, NaCH3COOCH3COOH(aq) + H2O(l) ---- H3O+ (aq) + NaCH3COO (aq)
1. What is the purpose of NaCH3COO in the buffer?
2. How does the buffer react when acid is added?
3. How does the buffer react when base is added?
I am not able to get the correct answer please help me
