Part 2 
 
Write the reversible reaction for Part 2 (include colors) 
 
 
 
For this reaction you need to know a few more pieces of information. 
 
1)<nowiki>HCl</nowiki> --> H+ (or H3O+) + Cl1- 
So, in a bucket of <nowiki>HCl</nowiki> solution, there is no <nowiki>HCl</nowiki> but only H+ and Cl1- ions. 
Therefore, adding <nowiki>HCl</nowiki> really means adding H+ (or H3O+) 
 
2) <nowiki>NaOH</nowiki> ---> Na1+ + OH1- 
Then the OH1- + H+ ---> H2O

Looking at the above two equation, one needs to realize that you can explain lab observations in two different ways with respect to <nowiki>LeChatlier's Principle</nowiki>.

2a) OH1- from the <nowiki>NaOH</nowiki> consumes H+ as in the above reaction so adding the chemical is actually a decrease in [H+] or

2b)OH1- from the <nowiki>NaOH</nowiki> reacts with H+ to form H2O so adding the chemical is actually increase [H2O]. 
 
 
So, for the reactions with <nowiki>NaOH</nowiki> below, please alternate explanation (once using 2a & another times using 2b).
