surface chemistry and solution chemistry


Surface Chemistry
We begin with some inportant definations in surface chemistry..
Preparation of sols
Some of the lyophobic sols are prepared as follows: 1) Bredig's Electric Arc method: This method is suitable for the preparation of metallic sols such as gold sol or silver sol. Water containing a little of alkali like KOH (in orde..
