Question

Chemistry lab questions ;
1) does the addition of concentrated HCl to saturated sodium chloride shift the equilibrium toward the reactant or product. How do you know?
2) HCl and HNO3 are both strong acids. There is a difference in the effect of these acids on the saturated sodium chloride equilibrium system. Explain the difference?
3) NaOH and KOH are both strong bases. There is a difference in the effect of these bases on the saturated sodium chloride equilibrium system. Explain the difference?
4) it is a fact that when acetone is added to saturated sodium chloride, the equilibrium shifts towards the right. What observation supports this fact. What is the role of acetone in shifting the equilibrium toward the right side?
5) what reaction conditions appear to shift the position of equilibrium to favor the formation of solid sodium chloride?

Explanation / Answer

NaCl --> Na+ + Cl-

1. On adding HCl, Cl- will be generated thus more Cl- will shift equilibrium towards left.

2. As HCl contains a common ion to NaCl

3. NaOH will affect the equilibrium due to generation of common cation of NaCl and it will shift the equilibrium towards left.

4. The addition of acetone precipitates NaCl (Due to formation of hydrogen bond between acetone and water), so equilibrium shifts towards right

5. addition of Na+ and Cl- will shift the equilibrium to form solid sodium chloride.
