  We re-examine the self-phoresis of a particle that releases(removes) pairs of
ions into(from) the electrolyte solution. We show analytically that in the
linear regime the mathematical description of this system maps onto that of the
correlation-induced (self-)chemophoresis (CICP). This connection provides a
unifying perspective of the two phenomena, within which one recovers and
extends recent predictions as particular instances of CICP. Conversely,
ion-phoretic particles are identified as candidates for experimental
investigations into the rich variety of motility patterns predicted by CICP.
