19.8 REDUCTION OF ALDEHYDES AND KETONES TO …
www.saplinglearning.comCatalytic hydrogenation is less important for the reduction of carbonyl groups than it once was because of the modern use of hydride reagents. It is usually possible to use catalytic hydrogenation for the selective reduction of an alkene double bond in the presence of a carbonyl group. Palladium catalysts are particularly effective for this ...

Principle of ion-selective electrode (I.S.E.)
www.sfu.caPrinciple of ion-selective electrode (I.S.E.) An ideal I.S.E. consists of a thin membrane across which only the intended ion can be transported. The transport of ions from a high conc . to a low one through a selective binding with some sites within the membrane creates a potential difference. See Fig. 15-8 for the development of a potential
