The volume of 10 ~N and 4 ~N HCl required to make 1 litre of 7 ~N HCl are
Options
- A0.75 litre of 10 ~N HCl and 0.25 litre of 4 ~N HCl
- B0.80 litre of 10 ~N HCl and 0.20 litre of 4 ~N HCl
- C0.60 litre of 10 ~N HCl and 0.40 litre of 4 ~N HCl
- D0.50 litre of 10 ~N HCl and 0.50 litre of 4 ~N HCl
Correct answer
D. 0.50 litre of 10 ~N HCl and 0.50 litre of 4 ~N HCl
Step-by-step solution
I et the volume of 10 ~N HCl used is x litre.- The volume of 4 ~N HCl used is (1-x) litre. aligned & 7= 10 x+4 (10-x) 1 & x=05 ~L aligned Volume of 10 ~N HCl and 4 ~N HCl used is 0.5 ~L , each.
