Question

If ionic product of water is Kw = 10-6 at 4°C, then a solution with pH = 7.5 at 4°C will

(i) turns blue litmus red 

(ii) turns red litmus blue

(ii) Be neutral to litmus

Joshi sir comment

question is not appropriate because for given Kw , [H+] will be 10-3 and max. pH will be 6 and the question is asking about a solution of pH 7.5 which is out of limit 

but if it is considered as a correct question then answer will be (ii)

Read 1 Solution.

at 4 C temp for water ie neutral , pH is 6  thus if pH is greater than 6 will be basic  ans will be 2 optn
