What is the pH of 0.0086M LiOH solution

The strong base will be dissociated completely into the aqueous solution. The pOH of the solution can be determined by the concentration of the hydroxide ion. The strong bases have lower pOH value.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.
