10 ~cm ³ of 0.1 ~N monobasic acid requires 15 ~cm ³ of sodium hydroxide solution whose normality is
Options
- A1.5 ~N
- B0.15 ~N
- C0.066 ~N
- D0.66 ~N
Correct answer
C. 0.066 ~N
Step-by-step solution
Volume of monobasic acid =10 ~cm ³ Normality of monobasic acid =0.1 ~N Volume of NaOH solution =15 ~cm ³ Normality of NaOH solution = ? gathered N ₁ ~V ₁= N ₂ ~V ₂ (for monobasic acid) aligned 10 0.1 ~N &=15 N ₂ ~N ₂= 1 ~N 15 &=0.066 ~N aligned gathered
