Colorimetric determination of carbon monoxide in air by an improved palladium chloride method.
The decrease in palladium chloride can be determined calorimetrically (2) and by means of iodometric titration (3). Christman, Block, and Schultz (4) determined CO in air by transferring gas mixtures to flasks at pressures of about 0.5 atmosphere, containing known quantities of PdC12. After 6 to 24 hours the PdClz which remained was converted to PdIz by the addition of excess KI, the pinkish re...

15 صفحه اولA Mechanistic Approach on the Solvolysis of Cinnamoyl Chloride in the Presence and Absence of Mercuric Chloride Catalyst
The order with respect to water in the solvolysis of cinnamoyl chloride in aqueous acetone and aqueous acetonitrile of lesser water content is H”2.6, favours an addion-elimination mechanism , S N 2 mechanism or a competition between them. Higher enthalpy and lower negative entropy of activation favours S N 2 mechanism. Order with respect to mercuric chloride in the concentration range of 0.001M...
متن کاملA Colorimetric Method for Determination of Serum Chloride.
HAVE INSTITUTED a colorimetric chloride procedure which has been in use for 3 years in our laboratory and has met with great success. This colorimetric method is based on a procedure used in automated syStems* (2, 3). It is extremely simple, quite accurate, and gives highly reproducible results even in the hands of student technicians. Those laboratories not having access to a chloridometer or ...
