What will happen if we add some concentrated sodium hydroxide to a saturated solution of sodium chloride?
A) NaCl will precipitate.
B) NaOH will precipitate.
C) We’ll get a salty solution that has a kick.
D) Nothing will happen.
Homework Answers
answer : A) NaCl will precipitate
explanation:
NaCl (s) <---------------------> Na+(aq) + Cl-(aq)
NaOH (aq) --------------------> Na+(aq) + OH-(aq)
due to common ion Na+ the equilibrium of NaCl will shift towards backward direction . so more NaCl will be formed. that means it will be supersaturated and NaCl will be precipitate out. this is the priniciple used in salting out
