Which of the following salts forms an aqueous solution with pH < 7?
Please list each reaction and why it's wrong or correct.
Also please write neatly, I've had a difficult time understanding the writing in some of the written solutions. I would prefer if this is typed up.
1. Na2S
2. NaCl
3. NaOH
4. NH4Cl
5. NH4OH
Homework Answers
NH4+ is conjugate acid of weak base NH4OH so acts as acid.Where as Cl- is conjugate ion of strong acid and doesn’t undergo any hydrolysis with water .So Cl- acts as neutral .So NH4Cl solution has pH less than 7.
