pH of 
is more than 7 as it is a basic salt. It forms NaOH as a base on hydrolysing. Hence , its pH is around 11.
but i had not ever heard about salt of ph is 14
IN SOME BOOKS PH SODIUM BICARBONATE IS CALLED IS MILD BASE
but in ncert it is said a basic salt
ya i know i saw it in some guides
and i was hella confused that what should i write
Look CBSE and Indian Education System is cr*p
here people are made to memorise wrong things first then they do the oxymoron thing.
No salt can be of 0 pH or 14 pH EVER because they are atlast made up after neutralisation or adding of metal.
ya u r right and then we get hella confused with whatever we learnt and its harder than other syllabus
hm.
