Why a little pack of Silica Gel (granular beads of Silica made from Sodium Silicate) is packaged with many new items to control humidity and avoid spoilage or degradation?
The silica gel molecules have a large surface area because of the pores of around 2.4 nm. So, it absorbs the moisture. Hydrophilic products are polarized and Hydrophobic molecules which generally don’t catch water are NON polar.
