Temp.:
25 °C

Any other information on results incl. tables

The Henri's law of MITC is measured at 25°C in dezionised water, in 0.1 M NaCl and 0.20 M NaCl, and in pH 4.0 and 83.0 buffered solution. The Henri's law of MITC did show dependance of ionic strength, increasing to 0.15 +/- 0.05 atm.M-1 at 0.2 M, but did not appeared to be pH-dependant.

Applicant's summary and conclusion

Conclusions:
Henri's law coefficients of MITC is 0.06+/- 0.05 atm.M-1 with a dependance with ionic strength, but not pH dependant.
