1.	The reactioin of sodium and potassium with humid air is violent and explosive. However, when these metals are kept in an air tight container having silica gel, no reaction has been observed. Give reason.
Answer» Solution :Silica GEL can absorb the moisture present in the air tightcontainer and thus air present in the container is FREE from the moisture . Metals Na, K can REACT with air only when the reaction is initiated with moisture . Therefore, when metals are kept in an air TIGHT container having silica gel, no reaction takes place since the air is ABSOLUTELY dry.
