Variables:
Room Temp: 283 - 313 $\pu{K}$
Prepared by:
Method/Apparatus/Procedure:
In a 175-mL milk dilution bottle fitted with a Bakelite screw cap and a Teflon insert and rotated end-over-end, (1) was equilibrated with an excess of (2), sampled with Hamilton syringes and titrated in an Aquatest II automatic Karl Fischer Titrator.
Source and Purity of Materials:
- Certified grade; washed successively with conc. $\ce{H2SO4}$, $\ce{H2O}$, $\pu{1 N}$ $\ce{NaOH}$, again $\ce{H2O}$, dried with silica gel, and distilled; $d^{25}$ = 0.87365.
- Obtained from the manufacturer; minimum isotopic purity of 99.7 atom % D.
Estimated Errors:
Ambient temperature: ±0.01 K
Std. dev. of soly calcd from 25-36 determinations reported above.
Components:
- Benzene, $\ce{ C6H6 }$; [71-43-2] NIST WebBook
- Water-d2, $\ce{ D2O }$; [7789-20-0] NIST WebBook
