Because of the way it dissociates

Answer 12

xplain

Answer 13

Think about electron pair availability. The more available the electrons, the more readily they can to donated to form a new bond to the proton and therefore the stronger base.

Answer 16

aravind in H3PO3 basicity is 2 becoz in this compound only 2 hydrogen can be given only not more than it as there is only 2 hydrogen it only seems there is 3 hydrogen
remeber all the H3PO4 or H3PO2 H3PO3 they are xception the way to solve these compound is u have to just subtract the oxygen molecule by 1
coming to ur ques in H3PO3 here oxygen have 3 molecules by subtracting it by 1 u get 2
NOTE: this trick is applicable on these xcption only ok
rest of the compound u have to just see the number of hydrogen molecules it will be its basicity..
