3 Grace marks in SCIENCE class 10 BOARDS
0 have signed. Let’s get to 100!
The question 7(set-1) in science class 10 boards(2018) says that the salt is used in making pakoras and has pH 14.
Baking soda(nahco3) is used in making pakoras but it has pH 9.
On the other hand ph14 ,as the question says, is of sodium hydroxide(naoh).
So there is a misprint in the question and it has 2 answers-- nahco3 or naoh
We should get 3 Grace marks on this question.
