Define a new exchanger with a new name and it should work. X has too much
baggage in the databases. Example uses Z; any unique alphabetic string can
be used; first letter must be capital.
EXCHANGE_MASTER_SPECIES
Z Z+
EXCHANGE_SPECIES
Z+ = Z+
log_k = 0.0
HCO3- + Z+ = HCO3Z
log_k = 0.9
TcO4- + Z+ = TcO4Z
log_k = 0.9
EXCHANGE 1 Hypothetical ion exchanger
HCO3Z 0.24
