Options:

A) $ 100,mL $ of $ 1\times {10^{-2}}M,H_2SO_4 $

$ +,100,mL $ of $ 1\times {10^{-2}}M,Ca{{( OH )}_2} $

B) $ 100,mL $ of $ 1\times {10^{-2}}M,HCl $ + $ 100,mL $ of $ 1\times {10^{-2}}M,Ba{{( OH )}_2} $

C) $ 100,mL $ of $ 1\times {10^{-2}}M,H_2SO_4 $

$ +,10,mL $ of $ 1\times {10^{-2}}M,NaOH $

D) $ 100,mL $ of $ 1\times {10^{-2}}M,HCl $

$ +,100,mL $ of $ 1\times {10^{-2}}M,NaOH $

Show Answer

Answer:

Correct Answer: C

Solution:

Blue litmus turns red if mixture is acidic, i.e., in which $ N_1V_1(acid)>N_2V_2(base) $

$ N_1V_1(acid),N_2V_2(base) $
