1) 2Na + 2h20 --> 2NaoH + H2
pure sodium metal dropped into 1.2L of water...
Gas collected occuped a volume of 4.68L at 25degrees caculate the final PH of the water NOTE: this is a 2002 paper so u have to use 1mole at 25degrees is 24.47L
2) In a titration the electrical conductivity of the reaction starts at a maximum then decreases to a minimum why does it NOT reach zero
3) Sorry one more.... how do you ensure Anhydroud NaCO3 remains anhydrous![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
THANKSSS IN ADVANCE
