Central Board Of Secondary Education [CBSE] — irrelevant question in science paper of class 10

Address: 411048

This is regarding the question no.10 of science paper code no.31/1 series tym.
The question was to answer a salt which is used in making pakoras with only hint given was that it has ph 14. There is no salt that has very high ph like 14 which is used in making pakoras and also such salt is very alkaline and unsuitable for consumption. The only salt that was given in ncert textbook was sodium hydrogen carbonate with ph between 8-9 and sodium chloride with ph of 7. Even sodium chloride can be used in making pakoras as the question does not states that the salt is basic or neutral only ph value is given which is wrong. Kindly take appropriate action at the earliest providing full marks for that question.
