1 с.c of 0.1 N HCl is added to 1 litre solution ofsodium chloride. The pH of the resulting solution willbe(2) 0(4) 4(3) 10

Answer»

Volume of HCl = 1 cm3​ or 0.001 LNormality of HCl = 0.1 NNumber of gram-equivalents of HCl= Normality×Volume= 0.1×0.001= 0.0001Volume of solution = Volume of NaCl + Volume of HCl= 1 + 0.001= 1.001 LAs NaCl is salt it will not contribute towards the pH of the solution.Normality of HClin resulting solution = 0.0001 / 1.001= 0.0001 NpH = -log[H+]= - log(0.0001)= 4
