Question

Are pH scale numericals important from the examination point of view ?

Answer 1

yes ! this is important because after chemical reactions how we find the acids and bases during production so pH paper is useful for view

Answer 2

If you are in the tenth standard u dnt really need it... because ncert doesnt prescribes it... although if you are in the situation of formatives...u should take care of it...as the question would be asked by your own teachers who taught you...while in summatives..the qstn are based on ncert pattern...so u dont need to take it too seriously
