Question

1 cc of 0.1 n hcl is added to 1 litre solution of sodium chloride

Answer 1

Answer:

Explanation:

Volume of HCl = 1 cm3​ or 0.001 L

Normality of HCl = 0.1 N

Number of gram-equivalents of HCl = Normality × Volume

= 0.1 × 0.001

= 0.0001

Volume of solution = Volume of NaCl + Volume of HCl

= 1 + 0.001

= 1.001 L

As NaCl is salt it will not contribute towards the pH of the solution.

Normality of HCl in resulting solution = 0.0001 / 1.001

= 0.0001 N

pH = -log[H+]

= - log(0.0001)

= 4
