Can someone explain the buffer system and neutralization reactions for me? I'm really struggling since our teacher just brushed through everything. I understand the basic concepts of acids and bases, but this just isn't clicking. Here are 2 example questions for reference of the particular concept: 1. Write the overall molecular equation for the reaction of hydroiodic acid (HI) and potassium hydroxide. Include physical states. Enter the formula for water as H2O 2. Consider the carbonic acid (H2CO3)/hydrogen carbonate (HCO3−) blood buffer equilibrium. H2CO3+H2O↽−−⇀H3O++HCO−3H2⁢CO3+H2O↽−−⇀⁢H3⁢O++HCO3− Does the concentration of H2⁢CO3 increase or decrease when HCl is added? Does the concentration of HCO3− increase or decrease when CH3COO− is added?

Can someone explain the buffer system and neutralization reactions for me? I'm really struggling since our teacher just brushed through everything. I understand the basic concepts of acids and bases, but this just isn't clicking. Here are 2 example questions for reference of the particular concept:

1. Write the overall molecular equation for the reaction of hydroiodic acid (HI) and potassium hydroxide. Include physical states. Enter the formula for water as H2O

2. Consider the carbonic acid (H2CO3)/hydrogen carbonate (HCO3−) blood buffer equilibrium.

H2CO3+H2O↽−−⇀H3O++HCO−3H2⁢CO3+H2O↽−−⇀⁢H3⁢O++HCO3−
Does the concentration of H2⁢CO3 increase or decrease when HCl is added?
Does the concentration of HCO3− increase or decrease when CH3COO− is added?
Expert Solution
Step 1

In neutralization reaction, an acid and a base react with each other to form H2O(l) and a salt. H2O(l) may or may not be formed, but a salt is always formed.

A buffer system either contains a weak acid and its conjugate base or a weak base and its conjugate acid.
