$($b$)$ Does the sentence shown in the box below provide a valid explanation for the fact that the

value of $H$ associated with the dissolution of KOH$(s)$ has a negative sign? Justify your answer

in terms of changes in attractive forces between particles that occur during the dissolution of

KOH$(s)$ in water.

Strong attractive forces exist between the $K^{+}$ions

and the $O{H}^{-}$ions in the crystal lattice of KOH$(s).$
