Central Board Of Secondary Education [CBSE] — science exam 10th grade

Q.14. The ph of the salt was given 14, but none of the edible salt can have 14 ph as it is highly alkaline and poisonous if consumed. If a different question was provided, the students might have answered it. But since the question was wrong many students have not answered it as they couldn't answer either of the question asked. I request that 3 grace marks be given to every student.
