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.

Order these chemical species by increasing pH of an 0.1M aqueous solution of each. That is, imagine making an 0.1M solution of each species. Select 1 next to the species that makes the solution with the lowest pH. Select 2 next to the species that makes the solution with the next higher pH, and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular...

LAB DESCRIPTION: In aqueous solutions the Ni2+ cation forms a complex ion with 6 H2O ligands. The formula of this complex ion is: Ni(H2O)62+. When this complex ion is mixed with aqueous NH3 a reaction occurs where some of the H2O ligands are displaced with NH3 ligands. But how many of the H2O are displaced by NH3? In this experiment you will mix nickel(II) sulfate and aqueous ammonia to synthesize a compound containing a complex ion whose formula is Ni(H2O)6-x(NH3)x2+,...
