Question

Two monobasic acids A and B are titrated separately aganist 1 N
Na2CO3 solution. 10ml of A requires 25 ml of Na2CO3 Solution,
whereas 40 ml of B requires 250ml of Na2CO3 solution.
What volume of A and B should be mixed together to
produce one litre of 1 N acid solution?​

Answer 1

Answer:

Explanation:

equivalent of a = 25

normality*v=25

normlity*10=25

normality = 25/10

equivalent of b = 250

normality*40=250

normality = 25/4

n1v1+n2v2 = 1

n1(1-v2)+n2v2 = 1

n1-n1v2+n2v2 = 1

v2(n2-n1) = 1-n1

v2 = 1-25/10 / 25/4 - 25 / 10

v2 = -15/10 / 15/4

v2 = 4/10=400 ml

v1 = 6/10 =600 ml
